On the IPR, the Red wire is battery voltage and the Yellow/Red stripe wire is the ground (provided by the PCM when commanded). Cheers!

you need 50 minimum... 55-65 recommended, that's why we all switch to e-fuel, the factory m-pump SUCKS

We don't "all switch". My mechanical pump lasted 21 years. I changed it then only because it was easy to get to.

Been awhile since I have been on here. On my 95 f350 that wouldn't start wound up changing out fuel pump and HPOP also the ipr valve. She's running like a champ. Thanks to everyone who helped me on this problem. This forum is the best. Thanks again.

To do it right you need a break out box that will shut down each injector individually.

But without one you can pull the valve cover and disconnect each injectors wiring and find it that way.

The FORScan app can do a cylinder contribution test with the engine running at operating temperature, and tell you which of the cylinders is bad.
