no spark Like the title says this is my problem. I have checked all wiring to cam, crank sensors, and found to be good. I have power to my coil packs, but for some reason I dont have spark. The computer has been tuned, and has the vats removed. So this is not the problem. What exactly would cause a no spark situation. I am starting to get aggrivated and need help. Thanks, josh

Crank sensor or ignition power. How are you checking power to the coil packs?

In other words, you have to make sure that you not only have 12 volts with the key on, but also when you are in the crank position. If not, you're on the wrong terminal of the ignition switch.

coil packs I have checked it with a test light on the coil packs while cranking. I know a test light isnt the most accurate way, but I havent had a chance to put a meter on it. The light stays constant while cranking. The individual coils are triggered through the pcm correct? Is there a way to test the trigger at the coil packs?
