99 gtp no start

Asked by Apr 11, 2016 at 07:19 PM about the 1999 Pontiac Grand Prix 4 Dr GTP Supercharged Sedan

Question type: Maintenance & Repair

I just rebuilt the motor in the 1999 Pontiac grand
prix gtp. Motor will crank, has spark but won't fire..
Haven't checked fuel pressure yet. Motor ran when
I pulled it out but it had a knock so I replaced the
crank and resized the rods. Got it back together
and won't start. Thanks for helping

1 Answer

I had all the wiring off the motor and computer unhooked would that cause an issue with the security systems??
