Just put new pistons in my 2001 gtx and now it won't start. It cranks but won't fire up. Sprayed some starting fluid in the air box to see if it was a fuel issue and still no start. I gotta grab my ohm meter and check the coils next. I checked compression and only had 25 psi each cylinder. I did some reading and a fee people said that it had to run for a bit to seat the rings and get the compression up. This kinda concerned me and not sure if that's the reason for it not starting. My gut tells me that it's a compression issue. Like to get some opinions before I pull the engine back out. Thanks in advance.
