I have a 97 GTP S/C and sometimes the car will quit and won't start until it sets for a few i just replaced the MAF and fuel pump. And the fuel pump doesn't engage until it sets.. It never started this until 2 weeks after the 1st fuel pump was installed.. I replaced the fuel pump again and it still continues to do it.. i have tryed checkin my #1 cylinder for spark when the car quits.. any help would be appreciated
