I have a 1994 3.4L Firebird. We bought it with a blown head gasket. When we bought it, it ran on all 6 cylinders. We replaced the head gasket, and started it up, and it only ran on 4 cylinders. Checked everything and found out that there was no compression on cylinders 4 and 5. We took it back apart and had the heads machined, put it back together, and now it doesn't even run. We checked for compression, and now there isn't any on 4, 5, or 6. We have thought about everything, and asked everyone that knows anything about cars; no one has a clue as to what could be wrong. What could it be?
