So I am completly stumped
Hey guys I am out of ideas. My rebuilt engine should run but it does not. Its not running on cylinders 2,3,6,and 7. This is my list of stuff I have checked and everything has passed.
-Plug wires
-Plugs
-Injectors
-Rockers
-Timing marks on the chain
New parts Include
- Gm Ac delco Optispark
- New plug Wires
- New plugs tr55s
- Rebuilt Engine
- New ICM and Coil
Today I went out and checked the timing by bringing each cylinder to top dead center and checking the rockers. I also was checking and could feel that the piston was at the top. I would also check my rockers and they were both down since the cylinder should be firing. So I am completely stumped. I think I am towing it so a shop and let them look at it. Just for a last chance anybody have any ideas?

Have you tested each of the Wires with a Spark Tester to determine that they are not firing?
I was just wondering..if you have Bent Valves then it's won't fire well either. Did you do a Compression Check?
Regardless if it's a major problem I would take it to a different shop than the one that re-built it, and make the first shop pay for it.

Well it was just the lighting strap so no change. Its going to a shop this week. I have had nothing but 7 months of straight trouble from this car. I had the engine rebuilt this 2.5 months ago and about a week after i got it back I have had this issue from the car.
