My 2005 Chevrolet Aveo has no compression and won't start.
I took out old spark plugs and installed new one's.
That did not correct the problem.
Replacing spark plugs won't fix a "0" compression problem.
You'll need to do a compression and cylinder leak-down test to determine the origin of the failure.
But first I'd check the valve-train timing. The timing belt may have broken or jumped teeth on the sprockets.
