What I mean is that I disconected the plug at the cold start switch and ran a + and - wire to the conector to activate it ,as long as the wires are ran to the conector the car runs great ,but as soon as I disconect the wires the car runs rough and won't rev up. I bought the TPI setup used. It came with upper and lower intake,fuel rail with injectors,throttle body, dist. and ECM. I had to buy new TPS, rebuilt MAF,TEMP,CSI sensor,knock sensor,oil pressure switch,coil,new cap,rotor,plugs,wires,engine wiring and dash wiring. I had a used O2 sensor and fuel pump switch. The engine wiring came with used both MAF and burn off relays,used fuel pump relay,and used ESC module. The only thing left to buy new is injectors, both MAF relays,fuel pump relay,ESC module,ignition module,air temp sensor,fuel pump switch and O2 sensor. So can any one tell me what I need to do next.

 

What are your current injectors running at resistance wise?

 

what motor did you have before? what type of induction? if you had tbi or carb, did you change the fuel pump? that was something you didn't mention. if you had tbi or carb then you need to change your fuel pump to one for multi port injection.
