Trying to locate fuel pump relay 95 sonoma

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

I've had an Alternator...that simply died and you just described the same scenario.

You could take it to a parts store and have them bench test it. Most do this for free. But I recommend doing that before I'd simply replace it.

You have not expressed that there was any noises such as clicking, tapping, whirring or such that would be indicating a relay or solenoid or even that the starter went kuuput. If it's trying to start and the belt was moving, my first thought would be to look at the fuel filter, even a few other compenents such as idle air control valves, sometimes these may need to be cleaned, or perhaps even the throttle positioning sensor.

But you say the engine simply stopped while driving, you say it has fuel and indicate the battery is good since it trys to start, but since the belt does not move. The alternator is what I would be focused on. Get it bench tested. If it is low and test show the amps are near or below the bottom scale for it. Replace it.

Hope you find something helpful in this

Good Luck and Happy Motoring

If you ran the tank dry then yes it is a fuel pump and you verified the problem with instant start fluid, you need a fuel pump

electronic choke failure look into that....

check the asr relay check if your fuel pump is getting voltage if not test at the fuel pump relay if it is replace your fuel filter check your fuel pressure replace the pump if it is bad

Fuel pump relay? When the engine is running the oil pressure switch will supply power to the pump.

Try using a throttle body cleaner, spray it in the intake, behind the butterfly and all that carbon will run out. You say the fuel pump don't seem to be working. Have you checked the relay. On the other hand can you hear the pump come on by listening at the gas tank neck. Have someone to turn the switch to ON position (not Start) and you listen to hear for the pump to kick on.Another way to check is to take the fuel filter inlet hose loose from the filter and turn the switch on and gas should be pumped out. If it does not, the pump is gone.

Probably not the filter, the Fuel Pump is located under the Back Seat.

hello, i hope this helps, it sounds like an open relay (bad relay). try swithcing fuel pump relay with AC relay and retest..if no sucess, feel free to reply and ill try to E-DIAGNOSE it for ya...lol.......good luck, marty

did you check you fuel filter and your fuel pump? i had the same problem and once i replaced the fuel filter its been fine since
