My car starts perfectly and drives fine for 15 minutes when my fuel pump begins an interminable buzzing. I replaced the pre-pump: same. I then replaced the pump proper: same. My mechanic now believes that the warm up regulator may be effecting the fuel pressure???? Any thoughts?? This is getting rather expensive .. considering that I'm still in school. Best regards, Jason
