Need to find feul pump relay on a 1994 olds 88 royal

AC clutch has to be energized for the compressor to turn and cool. Check out the thermostat as well as the low pressure cut off switch, relays for proper operation.

If you connect the 12 volts to the hot side of the clutch it should engage - if so that indicates that the issue is caused by some electrical item in line with the circuit that powers the clutch.

Air pump/Smog pump and Compressor go on first, on the shaft. Power steering goes on next Altenator is the last one. After market pulleys and the above mentioned parts may change this order.. 1983 olds delta 88 royale

pump: is in the tank.

filter: check underneath the car's driver side just in front of the rear wheel.

fuel relay: Under dash on the right side above the kick panel.

For 1994 Oldsmobile 88 3.8L SFI OHV 6cyl the Engine Control Computer is located front seating area, passenger side, under dash, mounted above kick panel.

Hope helps (remember to rate this).

sock in the feul tank may be stopped up.my just need a new feul pump. check feul pressure first when car will not crank.

Fuses (located on a swing down unit near the steering column or in the glove box) protect all the major electrical systems in the car. In case of an electrical overload, the fuse melts, breaking the circuit and stopping the flow of electricity.

I suggest check your 1994-Oldsmobile-Eighty-Eight-Owners-Manual for descriptions (page 223 and next).

Hope this help..

The solenoid is on the starter. The starter is located on the engine between the radiator and engine next to oil pan.

buy a haynes automotive book for your year it will tell you where and how to fix it.

My 88 ramvan did the same thing and it was the pickup sensor in the distributor. I replaced it and everything was fine. If the sensor is bad it won't let the fuel pump run or the ignition funtion.
