Dead on road. Fuel, IDM, IPR or....

[lbhbp]

We have a dead truck. Got it towed to nearest town. My fishing guide recommended a mechanic. After an hour+ and a diag that gave a P1283 code, his best guess was the IPR. I didn't have my computer so my wife looked up some things on your site. I asked him about the possibility of it being the IDM, PCM maybe the HPOP or a fuel problem. He wasn't thrilled with my questions. So, bieing 100+ miles from a dealer, he ordered the part ($300)and the next day installed it, test drove it and said it was ready. I picked it up, it ran great around town for 30-40 miles (better than before). So we hit the road and 20 miles later, it died. It gave the same code. Now I lost 2 days of fishing (plus the bill for the mechanic)and it is being towed to the dealer where I will have to go back and get it next week.
Before it died it had been running a little rough for some time. Wasn't sure if it was the tranny or engine. Then it began to be hard to start when the temp went below 50. I did change the oil just before the trip. I was driving along and had been for almost 200 miles when it started acting like it was running low on fuel (should not have been) so I switched tanks. It died. I started it again and went a little ways and it died again. It did that 2 more times and then would crank but not turn over.
So, it is at the dealer. I will talk with them in the am but I would like some advice so I don't get taken to the cleaners. Fuel, IDM, PCM or.....

Oh, 1997 F350 club cab, standard stuff with 178,000 miles. Only thing we've had to do is tranny rebuild, brakes, tie rod and power steering pump. Thanks!

Biased ICP sensor (try unplugging it truck will default) and see if it runs (drivers side head front)

Then check the wiring harness going to the hpop they are COMMON to go bad.....

after that I would say injector oring issue.....

[action4478]

Did he get a CPS code too ?..Did he also test the fuel pressure ..?...

[lbhbp]

He did get 2 CPS codes that he said were probably due to excessive cranking. They were 340 and 344 (maybe P340 & P344?). He "checked the fuel pump" so I am not sure if that means he checked the fuel pressure.... I talked with FORD service rep today but have not heard back from them. They were going to check it out and get back to me. From looking at prior threads last night I intend to talk with them about disconnecting the ICP and make sure they have checked the wiring harnesses I saw listed on this website.

[lbhbp]

So it was the wiring harness down near the fuel bowl.....What I found odd was that he said that the wiring harness itself cannot be replaced. They cut off the bad (IPR?) wiring harness and splice in a new one which is actually the same harness used for the glow plugs. Does this sound correct? It seems FORD would have a way to replace a harness rather than having to splice something....

[Evel486]

The IPR connector is the same as an injector solenoid connector. I have fixed them this way myself.

[Patrick Feeley]

If they spliced in a new IPR connector (which as Evel mentioned in the same as the injector connectors under the valvecovers), they could have replaced the fuel bowl harness. It isn't all that cheap ($65 at Powerstrokeshop.com) and there are two different ones depending on the year of truck. The early one seems to always be the expensive one. The later harness will work in both early and late OBS trucks (I used a late one on my 94 withough problems). Here's the part number:
