Do you mean no voltage on any of the relay contacts? Then check the fuse.
If you have voltage input to the relay but no output then check the relay. There should always be voltage on one side of the relay contacts, but on the coil contacts there should be voltage across them only when the ignition is on or engine running.

Changed fuel pump, truck will not crank unless fuel is poured into throttle body. when cutting switch on fuel pump does not come on, checked all fueses.


Hello...
The Sonoma has a Fuel Pump relay controled by the ECM "B" fuse and the ECM/PCM itself.
The relay is in the underhood relay box. 30 will be hot all the time 85 is your key. It will become hot for 3 seconds when the key is initially turned on. It will stay alive when the key is in the run or on position B if the ECM/PCM is working correctly.
If everything there is okay then its a ground problem at G102 or G402 or Wiring issue to the pump...
Good Luck

2001 GMC Sonoma Ext cab 4.3l, quit while running


Pull plug wire and install a philips screwdriver into the plug wire get it 1/4 inch away from a good ground and crank the engine over, is there spark? if so check that you have fuel pressure buy renting a fuel pressure test kit from schucks or auto zone and turn the Key to run position with the gage hooked up, it should read 50 PSI turn key off and wait 20 seconds should still have 20 PSI of fuel pressure, if no fuel pressure check fuel pump relay, then check fuse to pump. if you have a bad relay and are not getting fuel then check the oil pressure switch to see if you have oil pressure at the switch if no pressure then the oil pressure safety switch has died and needs to be replaced and should stark after replacing. If you have fuel then check the timing to see if you slipped timing belt.

What would cause a fuel pump to overheat


When the fuel pump is short circuit it will start going bad and thus gets hot. Replace witha brand new one. It will not cost much.
