Need help on my motor swap.
I just finished my s5n/a motor swap and now it cranks over but it doesn,t start and the motor from the other car was a 90 gxl mine is a 89 gtu so there are extra wires left over on the 90 gxl motor.so it seems like the car is getting spark but no fuel cause i dont smell gas at all and i took out the plugs and they dont have gas on them at all so could anyone tell me if the wiring harness has anything to do with the fuel pump or could anyone tell me what the injector wires look like cause maybe i missed a wire or maybe my fuel pumps gone or i wired the injectors to the wrong wires of the 90 gxl harness.does anyone know what iam talking about and can anyone tell me wut to do or if i did wire the fuel system wrong which are the right wires well hit me up a.s.a.p.peace.

Make sure your main relay is clicking when the key is on, before going to start...
Jumper the check connector for the fuel pump (on S4's it's near the AFM), turn the key on, listen for the pump...
If you installed a new fuel filter, make sure the flow direction is OK- some have check valves...
Make sure the fuel lines (pressure/return) are installed correctly at the "rat's nest"...
Injectors only have the small connectors going to them, with two wires each connector, seems kinda hard to forget to attach those...
Make sure all main harness connections that were disconnected are reattached...
Make sure the rear rotor housing ground was installed correctly (metal-to-metal contact)

Well i checked the fuel pump and its working fine but since i had to wire my cut wiring harness to the new motors harness the engine doesn,t seem to be getting fuel so i think we didn,t wire the injector wires cause there no fuel going to the motor so can anyone tell me which wires in the harness are the injector wires i think its the black wire with the yellow stripe down and is there anyone out there that has cut and wired there harness to another motor and can they take me step by step on the color codes of the injector wires since the gxl engine that i wired my gtu harness too has excessive wires left over i need help a.s.a.p.
