Hi all

My 1995 camaro when I try and start it lights turn on but engine won’t crank. I jumped the starter purple wire with the key turned on the engine rotated started and died. Checked all fuses in engine compartment and on driver side next to door all are in working order. I replaced the ignition key. I did VATS bypass. I pulled the blue wire harness from above the stealing wheel and tryed to jump it lights tuned on but engine did not crank. I added 12 volts to the yellow wire on the blue wire harness connection from the battery the engine rotated but died.

 

looks like some made a mess

 

need to be carefull putting 12 volts to anything going to the pcm. easy to burn it out. most signals to it are much less.

 

is this a lt1

 

Make sure you installed the bypass resistor to the wires going to the anti theft module and not the ones going to the key cylinder. Bypassing the starter relay will allow cranking the engine, but if there is still a key/VATS issue the injectors will stop working a few seconds after starting.
