        get your fuel pressure checked. ALsdo the pulsator (iirc), it helps keep teh pressure when the car is shut down for a while.

                  The problem sounds like your MAF. When the car is cold, it uses the MAF to control fuel. Once warmed up, most fueling is controlled by the O2 sensors. That would also explain the code.

                  I melted my MAF (nitrous backfire) so I went to Advance Autoparts and got a rebuilt replacment. I was still throwing the P0102 code. I took it back, they gave me another. Same problem. I went to the dealer, got a rebuilt MAF from them, problem solved. The dealer said that the aftermarket ones are crap and this is a common problem. Where did you get that MAF? If it is not from a GM parts store, take it back and go to the dealer.

                            starter would have nothing to do with keeping the engine running.

                              I would know exactly....if I pulled my reciept. However, I'm lazy. But, if my memory serves me right, it was $220.
