thinks for the heads up.is the blaster coil better than GM?i'm sure it is,but has there been any problems with them?seems like i seen someone with a problem with one,but i've seen more talking bad about the GM one.

 

Sorry to bring the old thread back to the top.....

My situation started off one day driving home the car picked up a dead miss. Then the car became hard to start, now it's impossible to start. I thought surely it was the opti. Replaced it and now still have the same situation.

I've gone back to the stock ignition !Crane, still same result.

I performed the test that Shoebox posted. Great technical information BTW. All the tests passed. What's the next course of action or items left to troubleshoot?

I appreciate the help.
