Did u put carb cleanor down the heads .. were the intake bolts too or just on the runners only ?  BIG NO NO

I would check your ground strap that hooks to the back of the intake.

Also make sure u re-attached your DIS connections. The do-hicky on the front of the motor. If they arent properly seated your motor wont start.

make sure your TPS sensor is hooked up and your maff

>7) cleaned the intake manifold by hand with carb cleaner
>8) cleaned IAB valve per instructions on FAQ
>9) cleaned intak on cylinder head with carb cleaner - basically a lot of carb
