I have a 1992 C4 with a 6-speed. She's been sitting for a few months, and when I got her uncovered and fired her up she ran for about 30 seconds, then just dropped dead -- as if I'd turned the key off. Now the engine just cranks and cranks... not so much as a sputter.
I've had this problem before, and the first time it was the ICM, the 2nd time it was the coil. I've only driven a few thousand miles since both of those were replaced.
I have good fuel pressure, and there's spark. I'm no expert, but it seems to me that when you mix air, gasoline, and electricity together something should happen.
I am, however, a little confused on what to look for with spark. I'm used to pulling a spark plug, and looking for that nice blue spark, but I've been told that I should use a spark tester on the LT1. The instructions say to set the gap to 10mm for electronic ignitions (which seems WAY too wide to me), and I'm seeing orange/white when it fires. What should it look like?
Could my coil be bad again already?? Would I get spark at all at the plugs if it is?
Thanks for your help guys!
