fuel pump problem
have a 99 grand marquis will crank good but no start if you turn key off and on several times then you will hear fuel pump finally kick on.does that mean fuel pump is going bad and needs replaced
Either that or the fuel pump relay is sticking. Replace the relay first. It's much cheaper. HTH. -Jim
Having the same problem, and I just put a new fuel pump in, and a new computer, and yesterday would not start, AGAIN. They called said it was working, went to pick it up and it didn't start. They are still checking, but I did get this off another site: "Had this problem and after paying a LOT of money to "experts" who had no clue, I finally found out it was the alarm system had gone bad and disabled the ignition and fuel pump. Took the alarm system off and all is well." & on same site this: "Aftermarket car alarm? I cant stress anymore to people, how installing one, is worse than Russian Roulette." So calling my mechanic...
