Another died while driving.

[merkfalc]

My wife was following me in our 03 F250 7.3l when she said it just died going down the I 35. She coaxed it over to the side of the road and couldn't get it to start again. It was pretty late so I didn't have a lot of time to check it out before getting it towed off the highway but what I think I noticed, because she was freaking out and that was freaking me out, was that there is fuel in the fuel bowl and the pump is turning on, there is oil in it, and I didn't notice anything on the dash out of the ordinary. A few possibilities cross my mind, but I want to make sure there is nothing else before I head out again (It's about an hour away at the ford house which was right down the street.)

1. CPS
2. Fuel Bowl Heater (Blew fuses)
3. IDM

Does that pretty much cover it? I bought the AE a few years ago, so I'll be able to pull codes if I can't figure it out while I'm there. I should also be able to check the UVCH but it would be a little odd if both sides went out.

Thanks for any help.

let us know what you find code-wise. and we can move forward from there

[merkfalc]

The only code I received was a p1212. From what I've been reading, it looks like an IPR problem. I ended up having to run service calls all day and only had about 10 minutes to work on it. I did check the HPOP and it looked like the oil level was good. Maybe an inch down. Hoping I have a bit more time to work on it today, or at least find a trailer to tow it back with.

while the ipr is a possibility, your problem isn't exclusive to it. this is an icp issue. too low.
that could be anything from a bad pump to a leak. first thing you want to do here, since you have ae, is pull up the icp and ipr PIDs. see what they read while cranking

this, and does the icp have oil around/coming out? Agree with the fuel bowl filter/unvh you mentioned. Also could try and unplug the icp sensor and see if that does the trick, quick way to check it anyhow

Sounds like a CPS to me. That's how a lot of them have gone out over the years. Driving along just fine, then death.

[merkfalc]

Well I wasn't able to get down there today to check it out, but I know that the icp did have oil in it. The fuel bowl heater was already disconnected so that rules out the fuses. I'm not sure of the procedure for testing the icp/ipr, but I imagine I can google it and figure it out. I'll go ahead and swap out the cps for grins, but the last time one went out it would start, just not run good. Thanks for the help, I'll give an update tomorrow.

[kaya@bernhausen]

the cps isn't going to cause a p1212. that's low icp. you need to first view icp pressure cranking and confirm the code

[merkfalc]

Ran some tests and this is what information I got from it;

Not starting

PSI was at 0
V was at .18
Duty Cycle was around 14.84

Trying to start

PSI went up to 2424.36
V went up 2.9
Duty Cycle 74.6

If I understand this right, it's either the IPR, the HPOP, or leaky injector orings. Since it is a no start, and there is oil in the HPOP, I'm going to go with the IPR. Does this all sound right?

[scagle1]

I'm pretty new to the AE , but have been all ove rthe net looking at the parameters for a few weeks since getting mine and the Duty Cycle looks high. I believe you are on the right track with the IPR being the culprit if it wont start in default with ICP unplugged. I know a year ago this truck was doing the same thing and it was the IPR , latest bout was the ICP but was throwing CEL and had a rough idle.
