This is likely the fuel pump. If the noise has gotten progressively louder, this is an indicator that the pump is going to fail soon (could be 1 day, could be 3 months). The fuel tank does need to be dropped for this repair. I would get a trusted professional to take a listen before I went and purchased new parts. If you would like to tackle this yourself and require instructions, feel free to let me know.

1997 GMC Jimmy started spewing gas fumes into garage after fill up, keeps doing it until it gets down to 1/2 tank of gas?


check for a leak in the gas tank above the 1/2 level it could have a pin hole. it could also be a bad vent valve on the tank or in the EVAP system that needs to be checked out.

Where is the fuel pump on a 1997 gmc jimmy


The fuel pump is located on the top of the fuel tank in most models, and it necessitates removing the fuel tank completely for access. The average backyard mechanic can replace a fuel pump in a Jimmy in about an hour.

My car keep cut off when im drive and a loud humming sound coming from the gas tank. what would be the problem?


the only thing in the gas tank that would hummmm would be the fuel pump, and would also cause the car to cut out. Try sraying a litle starting fluid into the air intake and try to start it, if it starts then you have a bad fuel pump

I WANT TO CHANGE MY FUEL PUMP ON A JIMMY 4.3 1997


You will have to drop the tank by removing the bolts on the straps and removing the hoses. Then beat the ring on the top of the gas tank off with a hammer and a screwdriver. Then the pump will just pull out.

MOST LIKELY THE FUEL PUMP HAS FAILED, WHEN U TURN THE KEY TO RUN POSITION DO U HEAR A HUMMING NOISE FROM THE FUEL TANK? THIS NOISE WILL STOP IN ABOUT 5 SECONDS, U CAN HEAR IT BETTER BY TAKING OFF THE GAS CAP AND LISTENING THERE, IF U HEAR NOTHING THEN THE PUMP WILL HAVE TO BE REPLACED.
