My 1999 F350 has 302,131 miles on it.
The water in fuel light came on recently and I cleared the water out and changed the filter. The engine developed a miss and it became progressively worse now the engine will not run.
I've had quite a bit of experience with these engines and have gone down the list of typical trouble shooting.
Changed Crank position sensor.
Fuel pressure = 55psi
ICP replaced the sensor and the pigtail, it was leaking oil.
Changed the pigtail on the IPR, insulation was cracking off the wires.
I put a test gauge on the high pressure oil port in the head. Cranking engine will build pressure to almost 3,000 psi.
I just got an Autoenginuity with the ford enhanced package yesterday and ran a buzz test on the injectors and it passed.
I get no engine related codes.
The ICP shows 14.8% with key on and goes up to around 50% duty cycle while cranking.
My thoughts are that with the oil pressure going that high while cranking the injectors are not functioning correctly, in that the oil is not going through them or the pressure would not get that high.
With this many miles on the truck I would assume I need new injectors but don't want to start blowing a bunch of money and find the problem is something else.
I am the first owner of this vehicle, and it ran fantastic until the water in fuel issue. I have maintained everything regularly. It has had no major engine work.
Any advice on how to diagnose this would be appreciated.
Thanks, Tom
