my ls wont start Hi, I just finished installing a rebuilt lsx into my 83 Camino. And now I cant get it to start. I have fuel at the fuel rail, and the pump cycles on with the ignition turned on. I have power to the pink wires on the coils. But after that I am not sure what I should be checking.
So I am looking for help trouble shooting so I can figure out what it is, that is wrong with it.
It is an LSX motor rebuilt with a LS6 intake and injectors, I used the throttle body off of the donor truck. I used the directions from LT1 swap. I thought I followed them to a T, but I guess not.

Please help

I bought a set of noid lights. I tested the injectors and the coils. Both have power when ignition is on. But nothing while the motor is turning over.
I installed a separate fuse box for the motor, that is supplied from the battery with a 40amp fuse. For the motor and the fuel pump.
But I will check to see if that is a possibility. If the power is constant. What else could be my problem.
I will update shortly on the power supply for these

i believe you should be on IGN1. I stays hot during cranking. One way you can test it is jump a fused 12v source directly from the battery to your 12v ignition input on the PCM. If the car starts you know you problem.

I just found the problem. Or atleast the current problem lol
I installed another fuse block with a master 40 amp relay to supply the other 15 amp fuses for the motor install.
The 12 v ignition wire for the master relay, does not have power when being cranked over. So no power down the line for every thing else including the fuel pump.
Thx every one. I will fix this. And then leave an update
Bought a cool new tool. And learned more about this motor.
Thank you Again
