You will not be able to hear the fuel pump on that model. First you have to determine if you get fuel and have spark. If it is a fuel problem, replace the DME relay first. Very common. They act up and fail without warning. Part is cheap and located in the fuse box. Next would be the fuel pump.
If it is spark related it may be the Flywheel Reference Sensors. There are two and the cost about $100 each.

Good Luck.

Hi, I think you have an airlock in the pump,You need to drain the water totaly when stone cold.Drain radiator and disconect hoses from waterpump and top hose from themostat. Reconect pump hose and add water slowly into radiator through top hose untill rad is full then squeeze bottom hose vigourously,You ll feel the water tension in the hose, Connect all hoses and top up water level. This must be done cold as hot and cold water will cause an airlock. Hope this helps you out.All the best.Phil

If you mean wheel bearings! You can check this by jacking up the wheel and grabbing the wheel top and bottom and moving it back and forth, if you feel movement then the bearings are worn!

AC could need recharging with refrigerant, take to a garage to get the level checked!

The dim headlight could be a bad earth! Check the earth connection to the headlight!

It is not a cable it should be an electrical sensor located on the left side of the transmission next to the driveaxle flange. This information is directly from a Haynes repair book covering 1983-1989.

VACUUMIt sounds like vacuum is not getting to the vent, heat and A/C controls. Find the vacuum can. It may be under the hood on one of the inner fenders. The "one-way" check valve is usually located in the line and close to the can, make sure it works properly. The valve could be the very thing that's causing the problem. Trace the lines back to the vacuum block at the intake manifold or fire-wall, and also back to where the line goes thru the fire-wall. Check the can for leaks or obvious holes. They used to be just a plain metal can, but it could be a plastic ball. Check the lines as you go, for breaks and rub-thru's. Move the controls thru all settings and listen for vent door movement. Worst case is a bad vacuum motor or air flow position selector switch, and/or a faulty Blend Door Actuator. If you have been driving around with the Temperature knob or control set at the same spot for months, move it from fully cold to fully hot several times and wait for the air temperature to change each time. This will help reset the blend door and vacuum control system. Hope this helps... Let me know what you find.
