Another Crank No Start
While driving Saturady after already being on the road about 3 hours in cold weather I was pulling a slight grade accelerating up to about 50mph, The Truck stalled & Started once, about 4 seconds later it did it again and then the third time Nothing, I was lucky enough to coast over to the shoulder and swap out a CPS as I had tripped a P0340 code.
2 CPS swaps later First a Ford unit, second a Parts store unit I purchased when I was broken down hoping for the best. I still had a dead truck. After trailering it home and hooking it up to an IDS Computer here is what I found:
55% IPR Duty Cycle
>10psi ICP Pressure, no thats not a typo Ten psi...
14psi fuel pressure measured at FPR With Analog Gauge
150-200RPM on Tach & IDS
Buzz Test Passed
Batteries 14v while scanning
I did not make a not of the pulse width.
Am I right to assume this is most likely an IPR Failure? I don't want to throw parts at this and I am lucky I have Diagnostic tools at my disposal to help troubleshoot.
