1998 GMC JIMMY won't start, fuel pump not humming, below zero
We have had below zero weather, and I wonder if something is froze up. It has a new battery, it's cranking but not turning over. I'm always able to hear the fuel pump, but not now. I have been keeping it full of gas, thinking I would not get water in the line. I sprayed a little ether on the carb, and it still would not fire. I can't find the fuse for the fuel pump either. Any help would be appreciated.

TURN THE KEY SWITCH TO THE ON POSITION ,WITH THE GAS LID DOOR OPEN DO YOU HEAR THE HUMM OR WHINE OF THE FUEL PUMP,YOU MAY HAVE TO GET A 2 PERSON SO THAT YOU CAN PUT YOUR EAR RIGHT UP TO THE FUEL DOOR TO HEAR THE HUM,IF THEIRS NO HUM ITS NOT GOING TO START.THE TANK THEN MUST BE REMOVED AND A NEW 250$ FUEL PUMP WILL NEED TO BE INSTALLED.THE PUMPS ARE ALSO DIFFERENT BETWEEN 2DR AND 4DR. EBAY HAS CHEEP PUMPS 100 OR LESS.
Try squirting a small amount of gasoline into the intake to see if the engine fires up. If it does, then the fuel pump is probably burnt out. Also, check all fuses, and inspect the fuel pump wires. Matt
Can you hear the pump running? If not why not check for power to the pump on the grey wire. Get as close to the pump as possible. If there is power you just confirmed the fuse, relay, and wiring are all good.
The relay is located on the firewall behind the plastic cover that usually has something like electrical center written on it.
the battery indicator light usually comes on after a lose of power. Sounds to me like either bad gas, clogged fuel filter or a bad fuel pump. Easiest way to check this is have someone turn the key while you stand at rear side of vehicle and listen for the whinning noise a functioning fuel pump makes as it pressurizes the system.
P.S you dont have to start vehicle to check pump. only requires turning the key to the on position. Good Luck
It's never a good thing to let Fuel Injection run out of Gas. The Fuel pump runs on Low Voltage and has a Hard time Restarting. Could also have had some (Gunk) at the bottom of the Tank that got into the Fuel System. Keep tryin to start Her for a while and see if the Pump won;t pick up. Also got a Long way for the Fuel to go to the Motor in that Suburban! Let me Know!
