No spark.

Have no Spark on a LS1 swap in a g-body. The harness and VATS delete was done by Wait4me performance. I have verified power when the key is in the Start postion. I have verified injector pulsing with Noid light, and the fuel pump is coming on when cranking. I have power and ground too the coils.
pulled a plug and get no spark when cranking.

There is a plug for the oil pressure sensor that is unhooked, the owner wanted to use a mech. gauge.

any suggestions, figured i would call Wait4me tommorrow but thought i would post.

thanks Scott

Make sure your 12v lead to pcm is getting power when cranking. It might have power when key is forward, but not when cranking. It happend to me, no spark when cranking either. Switched wire to another spot on fuse panel and fired right up!
