7 Cylinder LQ4?
Alright well I got my 6.0L LQ4 in my 1995 Impala SS running reliably...so I thought. I pulled the drivers side header off yesterday, and the #3 primary was absolutely perfect...clean as the day I put it on there. I used the GM Tec 2 to test the injectors with a noid light and they are all firing and it is getting spark from the coil. Fuel+Spark = boom...or at least it should...
I have no idea what else to check right now. I'm thinking it may be a compression issue, but would that cause it to not fire at all?

Put that injector in a different hole and see if it dies, if it does not try the coil. If both those don't work, check to see if the intake rocker is moving. If its moving check compression.
