Help! please 99 want start

[White99stroke]

I am new here guys, but i think i have a bad high psi oil pump gone bad or injector o -rings leaking, the truck just died changed cps,new fuel pump,inj. driver,pcm, we put a snap-on computer on it today and it said it had 120psi oil psi on the pump,but when i shot either in it to start it , it would shut up to 2500psi. so what do you guys suggest, or what do you think. any kind of help would be nice.

First don't use either. If it hits a hot glow plug it can blow a head right off the block. I have seen the results. It is very impressive.

Is the fuel pump cycling on when you turn the key to "ON"?

If you wait a couple of minutes with the key in the "ON" position, can you hear the glow plug relays turn off?

Is there power to the glow plug relays?

Second on the ether you are playing with fire, literally!!! Do you have any stored codes. I don't like replacing parts on a witch hunt. Let us know if you have any stored codes and you are sure you are getting fuel, with KO open drain valve, fuel should gush out at a strong stream.

yes, it is getting fuel and i know you are not suppossed to spray either in it but i just had to get it to pick up to see how much psi it had on it while it run for a second. The pump is coming on and the glow plugs worked to. I thought it had to have 500psi of pressure to crank.

I almost forgot it didn't have any codes showing. What will a pwrstroke do if it needs o-rings on the inj. do will it not have enough oil psi to crank the truck.

That would be a severe case, and unlikely. The best way to troubleshoot O rings is to send a oil sample the Blackstone Labs, call them and they can expidite you the bottles and you can over night them back if you are in a hurry. You would'nt believe what they can tell you from their analysis, I have mine done every third oil change. It will show fuel in your oil. Injector O rings get blamed for a lot of things on these forums, so does the CPS, so make sure what the problem is before you go replacing parts. PM me with any ? I will help you all I can.
