Re: ECM not getting power

Fuse in the battery junction box may be blown.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?

Re: ECM not getting power

What's with the guys at the shop?
Don't they do any troubleshooting?
There is fuses, relay, fuel, crank sensor etc to all consider.
They use a Scanner to check for any codes?
There is a difference between no crank and no start. Which is it?
Good luck.
