SOURCE: Pulling a fan clutch assembly from a GMC 4.3 water pump?

First remove the fan from the clutch. There should be four to six bolts holding the fan to the clutch. The clutch is held on to the pump with four bolts. remove the four bolts to remove the clutch. I've included a pic of the pump to indicate the four mounting holes. Not sure if the link will work.

SOURCE: I have a1994 gmc Sonoma. Fuel pump fuse keeps

The only other things on that circuit are your PCM(power control module) and the fuel pump/oil pressure switch. You can start with that but it is more than likely a ground somewhere on that circuit. If this helped four thumbs up please.

I have an 2001 GMC sonoma that will not start. The engine is getting gas, fire, air, and the compression is fine. The timing mark on crank lines up. What could be the problem.


you may want to check to see if this engine has a crankshaft position sensor, that tells the computer when to fire the distributor to the right wire. It might be the ecm itself. The best way to see if it is getting fire is to use a test light and while someone cranks the engine check the number one plug wire for fire. If there is no fire to the wire it can be a faulty ignition module in the distributor , ecm, crankshaft position sensor, bad wire bad cap bad coil. Go through process of ilimination

2002 gmc extended cab sonoma fuel pump replacement


Drop fuel tank, use brass drift and rubber hammer to unscrew retainer ring on top of tank. (Don't use anything that can cause a spark) Very carefully pull fuel pump and fuel level sensor out of tank.

Separate pump from unit and replace with the new pump. Wouldn't hurt to replace filter sock or filter if this model has one.

Carefully slip unit back into tank, replace seal and locking ring, ensuring it is tight.

If hoses and wires are long enough I check for proper operation before raising the tank all the way in place.

Once satisfied pump and fuel gage is working, replace tank in frame.

The ignition module in the distributor is what you need to give the engine spark to the plugs. It senses signals from the PCM to regulate the spark control and this item is the part that took over the old style point & condensor type ignitions. It is time for a new one in your truck

k, not cranking, is the battery good, if yes you could try to jump the starter and see if it cranks, if not you could pull it and have it tested. If the starter is good, might be the ignition switch.

4.3 vortec runs OK cold, runs rough or dies warm


replace the CKP and the truck will need to go to a shop and have the "crankshaft variation relearn" performed. the misfire may or may not go away, and that will need to be addressed also.
