Check for vacuum leaks, check to see if fuel pump pressure is within the manufacturer's specs, check to see if compression is good.

Well ty Jacob for reply, we went trough everything on the truck down to even checking timing chain and cam for worn lobes, ran down all wiring, compression, fuel spent endless hours. Well found the problem.

Was talking to a friend and he said how buying some things re-manufactured. Sometimes u get a bad one so I went to look up the PCM for my truck and it came up not for this vehicle I was like wtf, so I started cross referencing some numbers and found out the parts shop gave me the wrong PCM was for V6 and at the time I even had him double check fit to vehicle.

From now on I'll have part numbers in hand before I even enter parts store again.

Thank. Tim
