I HAVE A 89 GTA 350 TPI I AM NO GETTING NO INJ PULSE THE COLD START INJ WORKS BUT NOT THE REST ENGINE AND HARNESS IS OUT OF 87 IROC ANY IDEAS

 

BBT,

The cold start valve is controlled by the cold start control, mounted to the front coolant crossover of the intake manifold.

 

Not sure about the cold start injector, but a bad ignition module can cause the other 8 injectors not to pulse. Bench checking the module IS NOT a reliable check to see if it's good or not. I had a bad intermittent hard/no start condition on a 92 Z28 I used to own. It would also sometimes die on me for no reason at idle. Ended up being the module not pulsing the injectors.

Your problem could be a few things, but the module is definately something to consider.

Not sure if an '87 would have the low oil pressure switch to kill the motor or not. If so, you may want to check that out also.
