For the first time you realy need a baseline to work with to compare with,so a manual gauge would be the way to go just to get that,but since you have both installed, swap your plugs around and see what the coolant/fuel do then far as pressures.

 

I also have the eas and 100psi sensor and also watched the same you tube video, but haven't got around to installing it on my truck yet, but I think if I was in your position I would try to get a mechanical fuel pressure gauge to compare with your eas set up.

 

Switched up the plugs on the EAS, still around 22psi fuel pressure.

I’m thinking the fuel pump is weak. I also don’t know if the blue spring upgrade has been done in this truck.

What psi did these things run factory and what psi should they run after blue spring upgrade?

I’ll call Edge Monday to see if tech folks can advise if I have something set wrong.

You need to go into Mystyle and change the sensor range to tell it that it's a 0-100psi sensor - otherwise it doesn't read correctly.

jokester, here is a pic of how it’s setup in MyStyle.

Are you saying to change it to 0-100psi sensor, in the Mapping Dropdown, here? That’s the only 0-100psi and as you can see, it says 0-100psig-gauge. I thought that meant for a mechanical gauge.

Thanks,

TXPower

 

Yes, that's what i'm saying.

Yes, that's what i'm saying.

Ok, I did that while I was waiting for your response, still just 22psi max.

Testing it KOEO cycling the key to start the fuel pump up each time it built a max of 23psi one time.

I’m going to physically switch the sensors today between the coolant line and fuel bowl and see if that changes anything. But I really think the readings I’m getting are correct.

Otherwise, I’m leaning toward ordering a new Ford Fuel Pump and Blue Spring Kit tomorrow. I’d appreciate thoughts on this plan. Also, it seems the best price I’ve found on the fuel pump is on Amazon at $297. What do y’all think?

Thanks,

TXPower

 

When I did mine, I had the EAS pressure sensor, so it wasn't an aftermarket part, and I don't remember having to set voltage ranges.

If you wait for awhile after turning key on, it should go to 0psig when the fuel pump shuts off...does yours? That will let you know if you're getting the right reading or coming from a bad input.

-jokester

 

After the fuel pump shuts off the reading on the monitor drops 0psi, sometimes it reads 1psi but it drops rapidly to 0 or 1psi real quick once the pump shuts off.

TXPower

 

Hmmmm...

If you really had only 23psi of fuel going to the injectors, I would expect your injectors to be making quite a bit of racket from lack of fuel, especially under load. I will check my directions when I get home from when I programmed mine in Mystyle and post on here.

Thank you sir,

Did you ever get this figured out? I want to use the same sensor since its a lot cheaper than going through edge.

 

I haven’t yet. I went ahead and bought Edge’s Sensor, it arrives tomorrow. Once I get it installed it will tell the story. Either the sensor I had was right and I have low fuel pressure or the sensor was wrong and not compatible with the Edge System.

I called Edge first thing Monday morning, they were no help, just kept suggesting I buy their sensor. I did because it’s cheaper than buying a manual fuel pressure gauge setup to check against the sensor I have.

If the sensor I have was right, I still have it as a spare down the road. And if it was right, I needed a new fuel pump anyway most likely.

I’ll post back when I get it sorted.

TXPower

 

U can. Get a fuel pressure gage at harbor freight for 20 bucks it even has the right fitting to go into the fuel bowl

 

Well... :grin:

Well... :grin:

I broke down and bought Edge’s pressure sensor, it comes with the wire and connector. I paid for 2 day shipping. It arrived on Thursday evening. They sent a dry only pressure sensor. I called their customer service and told the dude the problem and suggested that they amend their online ordering to include a box the purchaser can pick to indicate whether they need a dry or wet sensor. The guy didn’t even respond to the suggestion. The dude tells me the correct sensor will be sent and I should return the wrong one they sent in the packaging the correct arrives in, which will have return shipping label. I said, that’s coming second day right, because that’s what I paid for to get this wrong one. The guy hesitated and acted like I was being unreasonable. Then finally said he would second day it.

On the heels of my phone call a few days before asking for assistance with mapping the sensors I had bought and their refusal to help, uh, yeah, I won’t be doing business with them in the future and wont recommend their products.

As an aside, looking at the wire they sent I believe I had the Pigtail that came with the other sensor I bought online, wired up right. So either that sensor isn’t compatible or there is some trade secret Edge doesn’t want to share concerning mapping it correctly, so your forced to buy theirs. Or, it was working and I truly only had 22/23psi on fuel pressure.

We’ll see.

Anyway Jokester, I’ll post up and let everyone know the outcome once I get the correct sensor.

TXPower

 

Any new results? I ordered a sensor off ebay cause it was $18 vs the edge one at $125. Hopefully it works.

 

TX, if it's any consolation

A) your setup looks right
B) your values are correct for the sensor in the MyStyle program

I know you went right to the expensive Edge sensor, but just keep in mind that sometimes these cheap little pressure transducers can be wrong too. I have a $20 amazon special transducer for my FP (might even be the same one just sold under a different name) and it works great. But if there were issues, I'd be verifying against a mechanical gauge before shelling out for an Edge special.

No one has asked yet....where do you have your sensor mounted? If it's in the cap, there could be an air bubble contributing to your low reading too.

FP should be around 50psi +/-5psi at an idle, the blue spring kit will bump that up to around 60psi +/-5psi.

 

Got a lot me to your $20 amazon special?

 

I sure don't. Bought it through my now ex-wifes account so i don't have any historical info. It looks exactly like the one the OP posted though, the name just doesn't look the same

 

Oh yeah forgot he posted the link. Here’s the one I bought. Looks to be similar.

https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/261260635816

 

Yeah I'll bet they're all the same imported generic sensor, just sold over different companies

 

So the correct sensor came in the mail on Wednesday finally. Should have been here Tuesday at the latest.

I’ve been working and haven’t had a chance to put the Edge sensor in yet. I’ll post up with results once that’s done.

I have to disclose that when I called Edge on Tuesday of this week to find out why my sensor hadn’t arrived yet I got another Tech/Sales Rep who really didn’t care that my sensor was late. I didn’t waste much time with him. Told him I wanted to talk to a supervisor. 1/2hr later a manager with Edge called me back. He listened to me and asked me what he needed to do to make it right? I was like I don’t know but my time is money just like yours. He made an offer to send me an additional sensor after he asked me what my needs might be in terms of additional monitoring. Long and short of it is, Edge went the distance to satisfy the customer. That’s big with me.

Oh, someone asked where I put the fuel sensor, whether it was in the cap. No, it was in the extra port on the bowl.

I should know tomorrow what my fuel psi truly is. I’ll ring back in then.

Thanks,

TXPower

 

hopefully it’s just that faulty sensor. Hoping for the best for you!

On a side not, can you post where you tied the coolant sensor in or pm me a couple pics. I’m about to add a coolant pressure sensor as well and just looking for a few ideas.

 

Yeah I second pics on the coolant sensor location.

 

Just to add to this conversation, my Edge sensor crapped out after about 14 months and 7K miles or so. Edge didn't reply to my email (still haven't, actually) then wanted to sell me the complete $130 kit to fix it when I called them.

Instead, I bought an ISSPRO ISS-R89141 for about $70 that worked perfectly.

 

Ok, so I finally got the Edge Sensor. SockPuppet bought a different one. Doesn’t mean it’s not right. The sensor Edge supplies is an ISSPro R89154.

I still only show 22psi on fuel pressure. I was told by Edge to configure it through the monitor by choosing 0-100psig, which I did. For those who have this setup, do I need to take the voltage values out at the bottom of the screen in the MyStyle. Or does it automatically fill those values in once the 0-100psig is chosen.

The fact that the other sensor and this sensor supplied by Edge agree on the fuel pressure, leads me to believe that I in fact, only have 22psi fuel pressure.

Next question. As I stated above, I don’t know if the blue spring mod has been done, whether it has or has not, wouldn’t a healthy fuel pump read more that 22psi. Thoughts?

I’m leaning toward buying a new Ford Fuel Pump off Amazon for $279.00. Or is there a cheaper place to buy it?

For those asking for pics of where I tied in for the coolant sensors here is a couple of shots.

TXPower

 

When I set mine up, I remember having to config it for 0-100psi and I think it filled in all the rest, but I can't remember for sure because it's been awhile. The instructions with the sensor should step you through it.

If you do need a new HFCM...

http://www.powerstroke.org/forum/pe...rg/forum/performance-drivetrain-parts/1306378-fs-brand-new-motorcraft-hfcm.html

I'd still get a mechanical gauge on there to verify 1st, but all signs point to your readings being correct. And you said you don't have any power loss or stumbling?

I didn’t get any instructions with the sensor when the first, wrong one, came. I called the tech line while waiting on the correct sensor and the tech said do the configuration through the monitor and choose the 0-100psig. There are no other choices when configured through the monitor so I’m guessing it sets all the other values too but doesn’t let you see them.

No sir, no power loss, no stumbling not even when accelerating hard.

If I could find a manual gauge for less than half the cost of a new fuel pump I would buy it and test but........

Thanks,

TXPower

 

A "decent" gauge to test with shouldn't be much more than 20-30 dollars.
Or this.

Or even this. More adapters, more gooder.

G8or, the second link you attached is an oil pressure tester. Will it work for fuel as well? I figured fuel would foul the gauge if it wasn’t built for that. I realize diesel fuel is treated thinner oil but wasn’t sure if that gauge would stand up to it or if the gauge internally would react wrong because of the different viscosity of fuel vs. oil. Thoughts?

Thanks,

TXPower

 

Like I said in my other post......from the pictures you posted, your MyStyle setup was done correctly for the sensor involved so you can check that off the list.

If you can verify against another gauge that's a good step.

When's the last time you replaced the fuel filters?.....see my previous post too for what "good fuel pressure" should be.

 

I bought the gauge in the second link posted above by G8orford today at Harborfreight. Will check it if there is enough light to do so when I get home from work.

Fuel filters were changed 8k ago. I change them, every third oil change. Is that sufficient?

Thanks,

TXPower

 

Ok, so I got home and hooked the manual gauge linked this morning by G8orford into my fuel pressure port and guess what....... 22psi idling dropping down to around 17 or so driving under demand.

Unless the fuel pressure regulator, spring inside it or something else is messed up, it’s time for a fuel pump.

Found the Ford Fuel pump and Ford blue spring on Amazon today about $360 for both, free shipping.

Unless y’all got other suggestions, ordering tomorrow.

Thanks,

TXPower

 

I'd probably try to verify line pressure first and possibly redo the blue spring before I replaced the pump, but it's your money. Adapting something to fit the line at the fuel bowl may be more work than just replacing the pump and regulator. Something else to consider is that it may be getting air in the system from a pinhole in the pickup tube or a connection. That would affect pressure as well.

@nighthawk285 is the expert though.

I'm far from "expert" but thanks. There's always more to learn.

IMO if you have two independent gauges that have the same readings like that, you likely have an issue and yeah, either have a weak pump or a big restriction somewhere. If you have no big driveability issues I'm going with a weak pump.

The nice thing about verifying against a mechanical gauge like that is that USUALLY you can also see the needle swing hard or wiggle in smaller increments that sometimes get normalized with an electronic gauge and sending unit. A 1-3psi constant wiggle would have me diving harder to find an air leak, but since you don't seem to have that it looks like you're on the right track with going with a new pump and regulator.

I too would replace the regulator first and then test again before swapping the pump...... at that point it doesn't cost you anything but the extra time and you may find a bad o ring or something at the fuel bowl that could be attributing.

 

Check that link I sent ya - that's an OEM HFCM for $250 shipped TYD. You can also pick up the blue spring kit from one of our sponsors on here @fordsvtparts and @Sunrisefordparts and still be under $360 with shipping. I do understand if you're in a time crunch though...Amazon helps out with that.

I bet you see a difference in power when you get your fuel pressure up :grin:

G8or, I’m totally ignorant to your suggestion about checking line pressure. Are you saying there is some way to check the pressure at the fuel line? If so, where would that best be done, what’s needed and how would the pressure differ there than where I’m plumbed into the dummy port at the upper fuel filter bowl?

And how would I go about determining if there is a hole or connection problem at the pickup tube in the fuel tank?

Thanks,
