Sous,

Yes the ICP sensor is full of oil which I assume means its totally compromised yes? It must use a diaphragm of some sort to measure pressure which I assume has been perforated and so fuel makes it into the sensor harness yes? Maybe? Anyway, that's been ordered. I unplugged it and the truck didn't start. I thought it could be unplugged and the truck would default to some algorithm for pressure adjustment.

As for the IPR (valve) wires, I didnt notice anything abnormal. How could I check for integrity on that circuit?

The only wires I noticed as being a little abused were the ones going into the yellow plug. They look a little bent as they entre the connector I think that's the fuel temp sensor.

The pool of fluid in the valley is diesel fuel.

I tried pulling codes using the TorquePro app but supposedly none were stored.

 

Not to confiuse you, but no 7.3 came with a fuel pressure sensor from the factory. Those would be aftermarket with a non stock gauge mounted somewhere inside the cab

 

You mean the yellow plug wires? Yes I agree. Does the truck look for signal from these to keep running?

Yes correct the electrical connection between the sensor and wiring harness was wet fuel.

 

The fuel bowl heater shares the same fuse ( #30 ) as the PCM, it can definately cause runability issues without blowing the fuse. Ask me how i know.

i can't tell if it's yellow due to your camera flash glare, but most likely yes that sounds right from what i can remember on mine

 

There is a black pigtail in the picture with a white? Weather seal, that looks to be where an aftermarket post filter pressure sensor would be mounted. Would not affect vehicle performance at all

 

Yes, based on your pictures and descriptions the ICP is completely compromised and should be replaced. It measures oil, not fuel.

Yes, the PCM will set a default parameter (700 I think) when the ICP is unplugged.

Yes, the truck should start and run if the faulty ICP is unplugged, but only if there is not another show stopping fault somewhere else.

Your right, the wires I saw that look damaged were not the IPR. Again, I am on my phone and was wrong.

As for testing the IPR circuit, I believe that KOEO there should be 12v at the connector, but I am not 100% on that. You could remove the connector and peel back the loom a few inches to inspect the wiring.

Is the tin nut securely on the rear of the IPR?

Are you sure you put the solenoid on the IPR properly after installing the valve body?

I think TP is a piece of **** program and I hope one day I can spit on the shoes of the guy that designed it. Forscan is not as pretty to look at, but works so much better. There is a Lite version for Android.

Try disconnecting the fuel bowl heater, wrap some tape around the wires separately and leave it disconnected. Try starting the truck then. Verify the wait to start light is still coming on too.

 

I labelled the sensors. #2 is the one with compromised wires, that I'm referring to. Is that the fuel bowl heater circuit?

 

Yes, from that angle the connector labeled 2 appears to be the fuel bowl heater.

 

The IPR solenoid cant be put in backwards because you wouldnt be able to plug in the harness. The tinnerman was snugged down yes. Its just a few inch pounds, but Ill double check.

Ill try that with the fuel bowl wires. I should have already addressed that. Silly me.

I have Autoenguity but I dont have the FORD extension. I need to get that. I use it for my other vehicles.

Ill check the wires for the IPR.

 

Your right about the IPR solenoid, but I have seen it happen at least once on the FTE.

Let us know what happens when you isolate the fuel bowl heater connector.

Battery voltage still good?

 

Is that the same as Water in fuel pigtail? Part 3U2Z14S411ARB.

 

Ok Im gonna try that next...isolate the wires on the fuel bowl heater to make sure they arent shorting.

I have the truck on a trickle charger 24/7 when not in use. One battery is new,the other is still in good shape.

 

1 IPR
2 fuel bowl heater and water in fuel sensor
3 aftermarket fuel pressure sensor

pooled fuel right there would most likely be from leaking fuel bowl drain valve orings

 

My aftermarket fuel pressure sensor (for the low pressure fuel pump) looks awfully wet doesn't it?

 

We only have 1 fuel pump in the system. 100psi output, regulated to around 55 psi. The sensor would not affect engine tho. It could be measuring the amount of milk sprayed out of a toddler's nose, engine PCM still doesn't see it's reading.

It could indicate your fuel bowl lid seal was improperly installed, but would expect much more fuel pooling and splashing all over ground after no start from that low of fuel pressure. If you havent rebuilt the fuel bowl the kit is pretty cheap, get it from Desiel orings, and spring for the florosilicone drain valve orings. But engine should still run with a little seeping
