Re: 1989 Grand Marquis died/wont start
It sounds like a fuel pump issue. If you turn the key on without starting it, you should be able to hear the pump run for a few seconds. You can repeat the key on to listen for it. There could be several reasons why it doesn't run. There is a port to check for codes but the OBDII wasn't until the mid 90s. That one takes a different tester.
