OK so my roommate pulled his built motor out of his DD and put his LS back in. The LS was a perfect running motor when he pulled it. We got the motor back in with the original harness, dizzy, and ECU. While the motor sat we stole the new timing belt off it for my Civic. We put a new belt back on before we put the motor back in. The timing is perfect and I have checked it and had my friend check it to make sure I havent lost my mind. It has spark on all four cylinders when I pull the plugs and stick a spark plug in the wire and touch it to ground and turn the motor over. It has fuel. I have pulled the dizzy off and turned it by hand while plugged in can hear each injector fire. I have even used my trick where you pull the plugs out and crank the motor over with a tourch over each spark plug hole and watch a fire ball shoot out. So with that said it has timing, spark, and fuel. I haven't checked the compression cause my buddy has my tester and I haven't gone over to get it (getting it back tomorrow).

ALL THE GROUNDS ARE THERE AND GOOD!!!

Any ideas on why it wouldn't start now? I tried a different dizzy that I know is good. So in my mind it has to be compression. But the motor only sat for 2 months so it's not like the rings completly gave out while it sat. So I can't think of any reason why it would not have compression.

Any idea's why the car wouldn't start now? He need's this car back as his DD ASAP. Thanks for all your help. I know HT can figure this one out.
