Question Still wont start

I need some fresh advice. I've got a 99 f250 that won't start or even hit. The history is simple. It would die without any warning and under any situation.sometimes I would have to work on it for ten minutes sometimes for ten hours (literally) then with no rhyme or reason it would just start and run like nothing was ever wrong. The problem became more frequent now hasn't started for months. Havefuel at the filter (both pressure and volume). Have changed the CPS. I'm convinced the problem is electrical as it won't even hit or bump on a shot or two of ether. Somebody give me some fresh ideas or info. Thanks

Does your "wait to start" light come on when you turn the key?

Get a scan tool and monitor the IPR and ICP. The IPR has to see a minimum of 500 psi to start. The ICP should show a minimum of .85v-.90v when cranking.

I think you're confusing the IPR with the ICP though,,,, If you unplug the IPR it's not going to do that, the IPR actually does the pressure regulation.

It's the ICP you can unplug and by doing so the PCM will default to a limp setting and control the pressure (through the IPR) at that setting.

You can visually inspect the IPR for a good connection, loose nut on the coil, or even "tap" it if it's sticking but don't unplug it

I think the 7.3 trucks are different than the 6.0's. But, maybe not
