99 Grand Prix starting problems

Hi All,

I have a 1999 pontiac grand prix with 111,000 miles on it with the 3800 V6 non-supercharged engine. I have recently fixed the infamous "intake leak" problem and have put the car back together.

When I tried to start the car, it will not fire. Are there procedures that need to be done with the fuel system after it has been taken apart (repressurizing, bleeding)?

I am very frustrated as I have been without the car for a couple of weeks.

Can anyone help?!?

Thanks, Terry

Welcome to AF!!

There really are no procedures for restarting. The fuel system should purge itself and the other systems should be plug and play. Make sure that you have all your connections back together properly especially at the ignition module. Also check the fuel injector connections and the TPS, Mass airflow and anything else that was disconnected. Other than that if the fuel pump is working and all plug wires are properly connected it should start.

Good Luck!!!

I agree with Lynn.

Just a suggestion but you might consider getting fuel pressure tested at the Schrader valve located on the fuel pressure regulator to rule out a fuel problem. Also, air, if any, can be bled at the Schrader valve with a typical automotive fuel pressure gauge with engine off and ignition in run (fuel pump prime). It has a purge/bleed button and an extra hose to discharge any possible air. It is not recommended to push in the valve manually while engine is running.

Thanks for the insight. Much appreciated!
