Sorry to bother you, but i've got a problem with my 1989 grand marquis LS.
It is intermittent, sometime it works fine, sometime it wont work.
I start the car and then when i put it in reverse or Drive, the motor stops. After it wont start. I wait 10 minutes, then it starts, i roll on the highway, and then at the first red light, the engine stops again... The starter works perfectly, in my Haines manual they say to chek the Relay...but in the 89' grand marquis, i dont find the relays(i dont think i have some).
I think it could be a bad ground at the fuel pump, but before taking the fuel tank down, i wanted to know what you think is wrong.
