My wife has been having issues starting her 04 gp gt2. Sometimes it hesitates a little then stalls while tryung ot start. She has also had issues with her fuel guage not reading properly but that went away. Today she went to start it and it did the same hessitation then stalled. She got it running but it is "bucking" and running rough. I was thinking fuel pump or massive air leak... any suggestions? Ive read that the pumps/senders are a common issue, and if the pump was letting fuel bleed back that would cause the starting issue. P.S. the car is not throwing any codes. I am at work and have not had a chance to look at it and she had to leave the car in the gym parking lot.
