My buddy did a burnout last night at the top of my street in his stock 91 vert auto and then about a mile down the road his car died, LOL, but yea we need to fix it now. I pulled the codes with KOEO and got a code 96 which was fuel pump secondary circuit failure/high speed fuel pump relay open or something like that. We dropped the tank and replaced the pump with my old one, no luck. We then took out his driver seat and replaced the relay, no luck. We check the inertia switch in the trunk and it was fine. So if anyone has had this before and any luck in fixing it please lend a hand.
