Truck only runs if i manually power ipr

[Jacup84]

I got my truck all back together will not start or build pressure on normal wiring.. if i put the 12v power to ipr and ground it my truck will run until you take off hot or ground wire... i can only think bad relay... been having one heck of a time. I got 1 code p2563 i believe saying icp regulator/open... my ipr is brand new

That code is for turbo charger boost position sensor.........i'm subscribing to see how many more threads you are going to start for your original no start problem. If you keep starting new threads, you are just going to have to answer all the same questions you answered in the first two threads. I'm having a hard time keeping up, so i'll just watch and hope you figure this out.

So all this started after you tore it down for studs, right? If so, now it sounds like you have a bent pushrod on #6. Did ypu position the crank dowel at the 6 o'clock position prior to installing the rocker boxes?

I never turned the crank. I just pulled heads off and reinstalled the new heads. Now you got me thinking i did a big ut oh?

[southend]

Yes you did, pull your valve cover, if you turn it over, you will probably not see the intake rocker move. Bent pushrod.

When I did my studs I never moved my crank. My understanding was that it was only completely necessary if putting back together with power tools. I used hand tools. Plus none of my pistons were at the top so I figured no valves should hit. I know, not a big help, but just my experience.

Just the rockers, inspect the rocker for cracks too.
