doing swap 91 dx odo to obd 1 ls wiring done put the ecu won't fire the injectors with obd 1 ls ecu put it works with a 0bd 1 p13 if anyone has any idea's please throw them out need help as soon as possible thanks in advance.

 

anyone have any idea's of wnat it could be

 

Are the injector ohms correct?

 

check your wiring. Your car probably had a TBI(throttle body injection). This setup only has 2 injectors and is wired differently to the ecu. OBD1 has 4 wires going to pins A1(inj. 1), A2(inj. 4), A3(inj. 2), and A5(inj. 3).

 

i double checked the pins in the ecu they are correct the car runs with a p13 so i don't understand why i does'nt run with a p75

 

update car ran with a p28 tryed 2 different ls ecu's neither works need help bad
