1986 Mercury Grand Marquis Questions & Answers
When I try to start
Is it just clicking, like the battery is dead? Will it turn over fast, with the spark plugs removed?
I would try using jumper cables, and try giving the starter a better ground -. Clamp to starter housing and negative side of battery. (NOT + TERMINAL) .
If these make no difference, I would buy a NEW starter.
Disarming alarm
If it does not share a circuit with another accessory...pull the fuse.
Installing sterio
Buy an installation kit to ensure proper connections...
Also, don't buy a DUAL deck...junk
