Thought it was the fuel pumps, but changing those out didn't fix the problem. As stated, car starts for a couple seconds and then dies. Could it be electrical?

 

Yes it could be electrical. Check loose or faulty connections at coil pack or alternator. Could also be a vac*** leak at intake and throttle body. Could also be a bad restriction in exhaust sytem, like bad catalytic converter. Could also be inefficent fuel supply to injectors.

 

Today I looked at my barbers 2008 deville with the North star engine. Guy from advance auto parts next door replaced the starter, well when he did so HE DID NOT let the tension off t he belt and slide it off the power steering pulley THEN REMOVE THE INTAKE MANIFOLD, he instead pryed the intake manifold up and broke it and knocked the plastic cap out of it, needless to say it had a NASTY VACUUM LEAK .

it would START, THE RPMS WOULD SKYROCKET TO ABOUT 7000 RPM FOR A DURATION OF TWO SECONDS, AND THEN DIE BECAUSE IT WAS RUNNING LEAN
