Starting and rough idle problem

I have a 02 with 175,000. It has a hard time starting I have to keep cranking on it and it will start eventually. Has a minor rough idle. Acts like it has to build oil pressure or fuel pressure is not where it should be. I put injector orings and rebuilt turbo about 4 months ago.

I should have mentioned this on my first post. This happens when its hot as much or more than when its cold. Drive it to work let it set a few hours and its really bad. Truck is still warm.

Make sure oil level is good, then check icp it tells the computer (pcm) what the oil pressure is and that helps determine injector load. You can check the icp by simply unplugging it and if the rough idle clears up immediately then the icp is the problem. Make sure you have fuel in filter area. After that I would check the injector harnesses then pull the valve covers and check the individual injector harnesses. These engines will vibrate loose the injector harnesses. please report back when you figure it out.

might be an issue with the fuel pump ... drain the fuel bowl turn the key to on nd make sure it fills up ... nd as far as ur most recent post check battery connections and connections to the starter nd if u hear the solenoid click when u go to start it but no cranking then try to beat on it while someone turns the key to start ... ur probably gonna need a jump or 2 or 3 if u were crankin for 2 minutes lol nd ur batterys might not be liking you so if theyre older than 2 yrs u might wanna consider replacing them ... that may actually help ur situation a bit (not the rough idle one but the starting one at least)

defiantly post up any progress and anything else that goes wrong or anything that seems funny that may help diagnose the issue
