Having problems with your 1983 Mercury Grand Marquis ?
Fuel guage doesnt work. ive tracked down all i can. Anyone got any suggestions. 1983 grand marquis 302 fuel inj
Open circuit - gauge will read full.Grounded circuit - the gauge will read empty. If it reads empty all the time - then the wire that goes to the sender is broken and/or grounded somewhere along its length to the fuel tank. run a jumper wire from bottom of the fuse box in the spot, all the way to top of sending unit on tank. disconnect old wire at both ends, and then turn on the key and observe guage. if not this, check guage itself for sticking.
Replace censor in fuel tank. Its at the front of the car so its a bit hard to get to but its there.
