You will need to drain the tank and disconnect the fuel lines. Then remove the holding staps.

1997 gmc sub/gas sensor


replace the fuel filter which on the drivers side, under the truck, by the rear passenger's side door. If nothing still, then you need to check fuel pressure with a guage, about $45 for the tool. I've used it about 5 times in 1 year. You will have to do some research on the proper starting psi. But it sounds like a fuel pump problem, which is in the fuel tank. I've changed one by myself, not too terrribly hard. But make sure the fuel tank is near empty, two bolts to undo, that hold the two tank straps up, get a jack with a wide plate, because you cant drop the tank all the way to the ground, otherwise you will rip the wires off. I replaced the pump on my 99 k1500 Suburban, 5 years ago. You also will need either plastic or metal fuel line disconnect tools (they are a pain to disconnnect). The pump costs about $275. Go with a pricey one with a reliable manufacturer, you only want to do this job once, per 20 years.

How do you access the fuel pump for a 1999 GMC Suburban.


you will have to drop the fuel tank to get access to the pump.you will have to remove all gas and vapour lines as well as electrical wires(plugs)as you drop the tank.its best to do this job with as little fuel in the tank as possible.you will have to support the tank with a jack and remove the tank straps then lower the tank.remove the sending unit lock ring and remove the unit form the tank,then you can see how to replace the pump.

1998 GMC Suburban. Did an oil change about a month ago and then changed the spark plugs, but now the car won't even start??? I have no clue now.


When you initially turn on the ignition switch,(before engaging the starter) do you hear a humming sound from the rear of the vehicle for about 3sec's? (sort of like a motor running) If not, you have a bad fuel pump. (The fuel pump is located inside of the fuel tank)

1996 GMC Suburban - Quit Running While Driving, Will Not Start


Listen at the back by the fuel tank for a 1 to 2 second prime cycle whirr from the tank when turning the key to run position after it has been off for at least 10 seconds.
No noise means no running pump.
....and no noise means.....
Most likely it will need a new fuel pump....80%
Fuel pump relay 10%
Fuse or bad wiring 10%

The quick fix to get home is to crank the truck to create oil pressure to fire the pump......and while cranking WHACK the tank hard with a 2by4 or something like that....to jar the pump..... and it may start running long enough to get it somewhere to be repaired.
This works 60% of the time on a dead pump.

If you do hear a whirrr.....you most likely need a ignition module or crank or dist pickup.

99 gmc suburban will not start unless pour gas into the throttle body"


IF YOU HAVE CHECKED THE FUEL PUMP FUSE AND RELAY AND THEY ARE BOTH GOOD THEN THERE IS A GOOD POSSIBILITY THAT THE FUEL PUMP HAS GONE BAD. YOU MAY BE ABLE TO GET IT TO PUMP ONE MORE TIME IF YOU BANG ON THE BOTTOM OF THE FUEL TANK WHILE SOMEONE ELSE TRIES TO CRANK THE ENGINE. IT MAY TAKE A FEW TRIES TO GET IT TO START, BUT THIS HAS WORKED NUMEROUS TIMES FOR ME. IF THE PUMP DOES TURN IT MAY NEVER RUN AFTER THIS, SO FIGURE OUT WHERE YOU WANT TO TAKE IT TO GET IT REPAIRED. THE TANK MUST BE DROPPED TO REMOVE THE PUMP. HOPE THIS HELPS. GOOD LUCK. THANK YOU IN ADVANCE FOR AN HONEST RATING AND FOR USING FIX-YA

Replace fuel pump on 97' Chev Sub 1500


The pump is in the fuel tank, you will need to pull the tank. But be sure the pump is bad first, check all the fuses, and the fuel pump relay, out under the hood on the pass. side,on the firewall.
