Sounds like you need a GPCM, but that isn't your only issue.

Is your FICM issuing a injector pulse width command?

You posted Sync, but is that cam/crank sync or FICM sync?

 

This above!! Need to know if you have cam/crank sync or FPW.

No fuel = no smoke! That says your FICM isn't telling the injectors to fire. As for your question earlier - yes, you should hear the injectors cycle at KOEO. Perform an injector electrical buzz test. You should hear all 8 cycle together and then each injector one at a time (3 rounds total).

I’m not sure about the pulse width command. As for sync, I’m using Torque Pro PID 2209cd. I believe that’s the FICM sync.

 

Cam / Crank Sync: PID 2209cd​

Min Value: 0​

The difference is in "EQUATION"

 

I’ll setup those PIDs and post the results tomorrow. Thank you very much.

 

My first thought was the FICM. But then you said you replaced it. So I'm inclined to ask if you can get the ficm volts using the pins on the top. Maybe you got a bad one. And I'm going to assume the batteries are good, and the connections are good from the batteries. Because bad plugs aren't your problem. But if you want to fix the bad plugs, it's common to replace the glow plug harnesses when you replace the GPCM, and go ahead and replace the actual plugs. I think the OEM plugs are 10 bucks a pop, and the harnesses are 80 bucks for both. But again, that's not your problem.

 

Sorry I didn’t post earlier but, our internet was down.
I added the PID’s and tested again. Here are the results while cranking:
Cam / Crank Sync: 1
FIPW: 2.0
EBP: 14.4
Batt V: 11.9
HPOP: 1423.3 (Slowly drops after I stop cranking)
ICP V: 1.6
FMP: 54.5 (Same as when testing at the terminals on the FICM)
FLP: 11.5
FVP: 11.0
IPR: 41.6
RPMs: 191.8
VGT: 0.0

I’m not worried about the glow plugs. It’s plenty hot out and I don’t need them to start the truck. The new owner can worry about that.
I just need this POS to start so I can get it out of my yard.

Thank all of you for the help.

 

Batteries are new and the connections are clean.

 

alright, please load test those batteries. They might be new but that po611 is a ficm failure. So your ficm is most likely being killed by the batteries if the ficm is new.

Edit:its also possible the glow plugs are drawing too much power from the batteries. It's a stretch but...

 

I went ahead and checked for codes again. The only ones I pulled are:
P0671
P0672
P0673
P0674
P0675
P0676
P0677
P0678

All of which are glow plug issues.

I also got a P0611. I believe that’s because I have a 56 volt FICM.

 

So the guy is short on money and you bought a 58V FICM to try (all computer resources.com)?

I don't understand that. Without more information or clarification, I would have to be thinking the P0611 is real and you have issues in the FICM, (but in reality you probably don't since a 58V FICM will work fine and throw a P0611).

EDIT - you could also ohm the injector coils themselves. A batch of 8 injectors has been known to be sold to a customer or two

Also - dirty oil has been known to clog all 8 spool valves before.

Lastly, just for grins. Disconnect both GPCM plugs and try to start it.

 

I still don't see whether you confirmed you have FICM sync or not. I see cam/crank sync is good and "sync" on your first couple posts is good, but you still haven't confirmed if that was FICM sync. That's a biggie...

You definitely have an issue where the injectors aren't firing for some reason. Have you done the buzz test I mentioned earlier? I wouldn't expect to hear anything since you don't hear anything at KOEO, but it's another diag tool.

-jokester

 

Yes, FICM sync is good. I have done the buzz test. It makes no sound at all. And disconnecting the glow plug relay made no difference.

 

You don't seem to understand the specifics. The GPCM doesn't have an individual relay.

Power from battery 2 goes to the GPCM for the glow plugs themselves through two wires - each with a fusible link.
VPower (control module power) goes to the GPCM from the PCM Power relay in the CJB, through fuse F2.22 (and to the GPCM). If anything pulls down the VPower, you will have processor issues - PCM issues maybe and possibly FICM issues.

So if you are saying you disconnected "the glow plug relay", I guess you are talking about the PCM relay. Of course if you disconnect that relay it won't start. That test doesn't make sense.

I am bowing out of this thread - too much detail requested and not gotten for me.

 

What I disconnected was the module that bolts to the right valve cover. I didn’t mean relay, I should of said module instead. I’m just reverting to the 7.3.

 

Also the owner of insisted that I order the 58 volt FICM. I didn’t see the use, but it’s his choice. I still have the one I took out of the truck, but will have to ship it off soon.

 

Post a link to a 58V FICM offered by allcomputerresources. I went through 13 pages of FICMs and didn't see it.

 

OK, so unplugging both connectors on the GPCM didn't change anything, then, correct? That's actually good news in a way (you take it where you can 🤣).

Do you have, or can you get a known good injector? If so, disconnect one of the more easily accessible injectors and plug that connector into the known good injector- retry buzz test to see if it makes noise then. This will let you know if it is the injector(s) itself(themselves) or upstream upstream in the wiring/FICM.

-jokester

 

Thanks, lol! If you do a search for FICMs on their website you get 13 pages of FICMs and nothing on those pages about the upgrade - I even added one to the cart thinking the option would come up there.

EDIT - same price as CBM, but has a lifetime warranty instead of 5 yrs. Hmm.

They seem to have a lot of BBB complaints though:

I don’t have access to another injector for the 6.0. I don’t know anyone that has a 6.0.

If you go to allcomputerresourcecom then click on the photo above where it says Ford FICM 6.0 you’ll see an option for the 58 volt “upgrade” just under the price.

 

And yes you’re correct, I did unplug both the connectors on the GPCM, one black the other green. And there was no change.

 

We'll get this figured out...it just makes it harder not being in front of the truck and knowing exactly what you're doing.

I'm still sticking with my original thought...need to figure out why the injectors don't make any noise during the pre cycle clatter.

Watch this video and see if it helps any. Sounds similar to your issue

-jokester

 

Very helpful. I’m going to try that now.

 

Well, no luck. I bypassed the relay just as it showed in the video and there is no clatter at all. I also tested the voltage going to the relay and the fuses. All of them showed voltage. I am also getting the high voltage at the FICM. I tested that on the FICM itself, not just with the scan tool.
Thanks for the video, at least now I know what it should sound like.

 

Yeah, it was a shot in the dark. I didn't think that was it, but it gave you something else to rule out.

Honestly, I think you're down to injectors or another FICM.

-jokester

 

Man, I’m not looking forward to telling the owner. I wish I had a definitive answer for him.

 

OP,

@bismic mentioned earlier about dirty oil possibly clogging the injectors. Have you done an oil change yet or at least drained some to check it out?

Also, I guess you could buy 1 injector and then use it to test the others...THEN purchase the other 7 if that ends up being the issue.

-jokedter

 

Oil is dark, but don’t look bad. However, it might be worth changing. I’ll see if I can talk him into that, and possibly a injector to check with. I’ll talk to the owner tomorrow and post what he says.

Thanks.
