In the engine compartment there are two pass-thrus. In the engine compartment on the one on the passengers side look for a tail that extends to 6" from the pass-through. This is the wiring to the fuel tank. The connector on the end of the tail will have three wires
Tan/White - Fuel Pump Power
Pink - Fuel level sender
Black - Ground
Unplug the connector. Turn the key to on. On the tail that came through the firewall ground the pink (center) wire. The gauge should swing to empty. If so everything from that point up to the gauge is working. If not then you have to look towards the tank.
If not look for the trouble to be in the tank.
As a second test - on the tail that runs to the tank - You should measure 0 (Empty) to 90 ohms (Full) between the Pink (sometimes Purple) middle wire and the Black ground wire. Don't confuse 0 ohms (direct short) with infinite ohms (an open).
If the trouble shows to be in the sending unit, I would recommend replacing it rather than trying to service it, well unless you are a real cheapskate. It is a total pain draining and dropping the tank if your repair doesn't take. Also make sure the gauge sender IS WORKING before putting it in the tank and putting the tank back on the car.

HAYNES and CHILTON are on the way. Also, I found a workshop manual for '84-'87.
Other than suspension, are there significant differences in the '88? I'm particularly concerned about electrical and ignition changes in this car...
88 Ignition (2.8 V6) is the same as all the other years of the 2.8
The 88 2.8 alternator is different than the 85-87
