My friend has a Chevy Z71 pickup with a 350 in it. He said it falls on it's face when you accelerate, unless you baby it. He said it just started all of a sudden.

He's been told it may be the TPS sensor. Could that be the culprit? If so, how do I diagnos this for him? I know how to set the TPS on a Ford. Is it similar?

I assume it is an electrical or fuel problem since it was running fine one minute, then crappy the next. Any other ideas?

Any help you could give me on this matter would be greatly appreciated.

2Fast, how many miles are on this truck? i will bet you ten to one odds its the fuel pump. i replaced alot of them in the fuel injected chevy trucks. since that is a vortec, if the fuel pressure is up to spec but drops with the key on engine off(priming), pull the upper intake off and look at the fuel lines that go into the intake(yes they are in the intake!). those usually crack a piss fuel in the intake and the truck runs REALLY rich. i am almost positive it is one of the two i mentioned.

let us know. James...
