7.3 ongoing no start issue

I've been having a ongoing "no start" issue with my 7.3 the last few weeks.

We went on vacation a few weeks ago and the truck sat for a week. When we got back it took me a few tries to start it, and usually it fires up first try. So I got it running drove it around that weekend with no issues.

The following Monday morning it wouldn't start again. I tried changing the CPS and glow plug relay, neither worked. Then I changed the fuel
Filter and that didn't help either. After that
I thought to check the HPOP resivour, it was low so I
Added some oil to it and the truck started right up.

Fast forward about 2 weeks.

There has been a few times where I would have a hard time getting it started in the mornings but it would still start.

Now yesterday I went out after work to start it and it just cranks but will not start. The tach bounces while cranking, so the CPS is good. The oil level in the hpop was low so I filled it again and filled the crankcase also, still no go. I was thinking injector orings might be on their way out, but I pulled the fuel filter and the fuel is still clean.

The truck is now spending it's 2nd night in the parking lot at work, and I don't exactly work in the best neighborhood.
Any help is appreciated... This thing is really starting to tick me off...


UPDATE:
Used some ether and got the truck started last night (yes I unhooked the glowplugs) drove it home and plugged it in. It got down to about 50 here last night. Tried to start it this morning and it just cranks.. And cranks, and cranks some more

Help please!

Have you checked all your fuses? Make Sure none of them are blown, also if you replaced the cps and didn't a factory ford one that could also be your issue.

Also don't keep cranking the engine over your going to fry your injectors.

Fuses are good... I got a autozone cps, and it was working, the tach bounces when you crank it... I do have a motorcraft cps that I could try.

It wont fry the injectors unless he gets smoke when he cranks, if theres not proper pressure of oil or fuel in the rails they wont even try to fire.

OP check this out it may help Diagnosing a 7.3 no start

Sounds like you have a weak LPOP

I had a friend with a 96 that would not start. Tracked it to a bad CPS. He got one at O'Reilly (BWD brand). I installed it, no start. Re-checked everything and it still appeared to be a CPS. Got one at the International dealer and it started right up and running perfect every since. No more aftermarket sensors for me. Might as well try the Motocraft since you already have it.

Still haven't got this turd started...
A guy from work came over the other night with a scan tool And we figured out the IPR was bad.
So tonight I pulled the fuel bowl out and replaced the ipr with a motorcraft one.
Got it all back together and nothing.
Opened up the fuel filter and the bowl filled itself back up with fuel so that rules put the fuel pump...

Hpop gone bad?

Did anyone try the ICP sensor? Mine was doing the same thing a couple months ago , ZERO start after draining all juice out of 2 new batteries. Started starting after ICP sensor was changed & now dies ignoring accelleration. So, troubleshooting all the strange symptoms, including those around when it does run, it has so much terrible trouble around lower accelleration it can't actually qualify as 'running' when it dies 'run' if you can call it that, it does do better at high accellerating then when you have to let up on the accelleration pedal. Mine' a 1995 F250 PowerStroke 7.3.

Haven't tried replacing it but everything I've read says if its on its way out you should be able to fire the truck up with the ICP unplugged. I tried unplugging mind and still wouldn't start.

I really appreciate this thread. I have been going down your list. I got to the lift pump and at the shrader valve it's only getting 15psi while cranking. It should be at least 35psi right? Truck is a 95PSD. No start with no smoke scenario.

25psi should be good enough when cranking. 50-60psi when idling.
