Well I got it to start and it sounded just fine, ran untill it got up to operating temp and then died fast, no studder just died like i shut off the ignition. After that it wont start to well and if it does its hard to keep it running. I have to keep my foot on the gas, pretty much to the floor to keep it running so i stopped working on it till I know whats going on. Any advice would be appreciated, Thanks...

 

Is your intake tubing to the AFM all connected with no leaks? Check all your distributor wiring, Short B+ and FP in the diagnostic terminal to force the fuel pump on and see if it runs. If it does then I would look more into the AFM, COR relay.

 

Oil and water?

 

Ok, ill go check it out... Would it do this if there was a blockage in the radiator or cooling system?

 

ok, had some vac hose issues but thats now fixed. It runs and stays running, but now the problem is it has absolutely no power what so ever... While in gear with foot to the floor has enough to push the truck maybe 10MPH if that. Out of gear if I try to bring the RPM's up its pretty slow on the way up even with foot to floor. can anyone help
