I just replaced the motor in my pickup, the truck was setting for 5 years. It has a 22RE EFI and I also had to replace the ECM and coil. The TPS, plugs, wires, cap and rotor are new as well. I had to replace the fuel injectors. Last night a friend of mine checked all the vacuum lines on the truck. I'm at a lost it wont stay running and I dont know what too do.

Is the fuel pressure OK? Maybe the fuel pump is going bad and the engine doesn't get enough gas. Or a clogged fuel filter. "Won't stay running" isn't much to go on.

It's a new fuel filter and we did check the fuel pressure and its fine. Well we did finally get it started but it wont stay running. Everything on the truck is new and I'm getting so mad.
