hey guys kinda new here been trying to diagnose my grand prix but im havig some problems! it all started a couple months ago when my car died randomly in my parking lot but started up the next day. after that no problems for a couple weeks until it started to stall out on me on my morning drives to work. it would stall out no sputters or anything just dead. it would start up the 3rd or 4th try. I started to do this more nd more so I left it at my parents house for a month or so so my dad could get it looked at. needless to say he takes it into his shop the tech runs it on the scanner for 2 hours and nothing happens. he continues to drive it for 3 weeks and no problems at all! no I get my car back and it dies not even a mile from my parents house I trun it over nothing I try 5 times then it turns over finally! I was fed up. so I changed my fuel filter which was nasty btw clean my air filter, throttle body, IAC and replaced the fuel pressure regulator. after all that she died on me the next day. I have now bent the tab on my #15 relay for the low to high speed fuel pump. what can I do next ?! 2000 Pontiac grand prix gtp 231,000 miles ! hope you guys can help!!
