Please Help!! Truck Won't Start!

[95BLACKSTROKE]

I have a 1995 Ford F250 that won't start. I have replaced the hpop, ipr, fuel pump, icp, fuel filter, cps, glow plug relay, and the truck has brand new batteries. Truck turns over but won't start. I installed a gauge on the oil rail and it indicates that I am only getting 200 psi of oil pressure from the new hpop. The tach moves up and down when cranking when means the cps works, correct? The starter sounds like it is still in good condition. I managed to start it one time but it only ran for a few minutes and died. I couldn't get it started again. I really need help! I don't have the money to pay the stealership so they can troubleshoot it at $55 an hour. Could it possibly be my wiring harnesses under the valve covers? I ran an injector buzz test with an actron scan tool anfd it indicated that it passed. I assumed the buzz test would prove the harnesses. I do have a wait to start light. Does anyone out there know or have any ideas on what I should try next?

Does anybody have any suggestions? Any advice will be greatly appreciated!

Any suggestions anyone out there?

check for oil leaks im pretty sure cranking oil pressure needs to be around 2000 not 200 and go from there

I am going to remove the valve covers to see if maybe the oil rails are leaking or maybe inspect the injector o-rings. I have the gauge installed on the passenger side oil rail. It shows 200 psi when cranking. Thanks for your advice.

From my understanding you need at least 500 psi to start. Mine has 3000 while cranking. You might want to check the coil(not sure the actual name) at back of the hpop. It has to actuate for the pump create enough pressure. You can test the resistance through the coil.. I think it needs to be 10 ohms... Not sure. You can also check the voltage between the 2 wires that plug into it. It should be full 12 volts when the key is on.

Thanks for your advice, I'll try to check the ipr (injection pressure regulator) to see if it is at 12 volts. I willalso check the ohms. I am coming up on some days off from work this weekend so I'll try it then. I'll keep you posted. Me research has come up that these trucks need to have 500 psi when cranking and runat 3000 psi or somewhere in that range. I downloaded some literature from Diesel Technician Society online. The info on the website is very informative. Check it out. Just google Diesel Technician Society.

It's the CPS villain at work again. I've had mine replaced three times in just over three years. Check out my thread on this that I just posted this morning.

Good luck!

Any white smoke out the tailpipe while cranking?

I don't have any smoke while cranking. I guess that means I'm not getting fuel?
