Hiya.



I just bought a 1978 Grand Marquis. It drove fine for 2 days, and then
today, I started it up, let it warm up for about 10 minutes, and went
to back it out. The needle that indicates whether you are in drive or
reverse or park got stuck.



I managed to jiggle it back in place, but when I started it again, it backfired twice.



Once I got it going, I figured it was okay, but when I drove it to the
store, I came back out, tried to start it, got nothing. My roommate
came and jumped it for me, and it seemed to be fine, but now it won't
start again.



Anybody have a guess as to what might be causing this?

SOUNDS LIKE THE BATTERY IS GOING BAD AND SHRTING OUT DUE TO YOU AN JUMP IT AND IT WILL RUN CORRECT? ALSO THESE CAR HAVE WHAT YOU CALL A DURA SPARK MODULE LOCATED ON THE DRIVERS FENDER WELL WHICH COULD HAVE CAUSED THE BACKFIRE WE HAD ALOT OF PROBLEMS WITH THEM BUT TO START HAVE ALT CHECKED OF OK THEN HAVE BATTERY REPLACED NOTE ALL THIS SHOUD ONLY BEDONE IF THE CAR RUNS AFT YOU JUMP ITHOPE THIS POINTS YOU IN A DIRECTION
