first off i do know alot and understand alot about cars but this one has me stumped, ok this is what it does i can go out in the morning when its cold and it will crank up and run. once it gets hot when you crank it up it runs like its on 2cyl or not crank at all sometimes i have to spray starter fluid in it. will eventually smooth out after about five mins. now here is what i have done to TRY and fix it, run non ethanol gas, clean cold start injector changed fuel pressure regulator, fuel pump, complete tune up thought maybe it was the mass air flow sensor but put my buddys on and no dice. the previos owner cut the fuel pump wires out from under it (dont ask why) i cannot located the wires so i wired it to the fuel pump relay behind the glove box... i am stumped and tried everything if you know what will help me id greatly appriciate it.

 

Here is a link to what I went thru. Alot of the steps I did will be part of the things you probably need to check on post #664. Link>>> https://www.yotatech.com/forums/f199...9/index27.html
