Hi,
I have a 1986 z28 with a 305 TPI engine. I recently replaced the engine with a 383 FI and hooked it up to a holley commander 950. I get spark, crank and fuel but it won't even hit. I have the 950 computer hooked up to my laptop and everything looks good. Any ideas? The 383 engine was a total rebuild.

Thanks,

GWFAMI
