so what do u think my problem is then, i can start my car when its cold, when its warmed up it starts to surge a lttle bit but, then i rev it up and it goes away. if i go somewhere when its warmed up and i shut it off, when i go to start it back up it wont start untill it cools down.

ill turn the key and ill hear the fuel pump come on and the motor wants to start. i have 42 lbs of fuel pressure to the fuel rails with key in on position. i spray starting fluid into the throttle body and itll start but instantly shutoff so i know i have spark.

so far i have bought an ecm, fuel pump, fuel filter, spark plugs and wires, theres a new distibutor in it, oil/ oil filter, my gas tank was checked for buildup and there was nothing in it, if u know whats wrong or what could be wrong please tell me. im starting to run out of money

ps. previous owner tampered with wiring harness to remove lights and sirens ( car was old DARE car)
