My truck died on me. Tried starting it & it turns over just fine. I got fuel in fuel bowl got fuel pressure. Got oil in hpop. When I turn my truck over I got no smoke so it's not firing. I'm thinking it's either the hpop went out cause of my stage 2 injectors or the IDM went bad. I don't know I'm jus kinda at a lost.

 

Well its really hard to diagnose an issue with out testing anything., you first need to check your actual fuel pressure, then your HPOP oil pressure which needs to be above 800 PSI cranking. Also look at your tac is it reading, if not getting above 500 RPM it will also not start.. Or you can get a scanner on your truck you can quicky diagnose this issue within 30 minutes..

 

How can I check my hpop pressure & I can't plug a scan tool in cause I got a bad power wire to the plug in & I don't know bout the tach but I know it's below 500 cause it's not putting any fuel out

 

You will have to put a mechanical gauge on it if your OB2 isn't working

 

Where's the best spot to hook up the pressure guage for it?

 

At one of the High oil pressure galley plugs or remove the ICP or IPR on the driver side of the head close the the HPOP.

 

Just for grins, get a friend with known good batteries to jump you off. If you can get that motor to spin fast enough (and the IDM is good, and the HPOP is topped off) ... that baby will crank.

It will crank, but inless the IDM is reading 800PSI at the High Pressure oil galley she not gonna start...
