1997 gmc suburban fuel pump removal?

Question

Anybody DIY a fuel pump for a 97 GMC suburban

Answer 1

All fuel pumps for GMs are located inside the fuel tank. Either remove the fuel from the tank or remove the fuel tank with the fuel in it. It is a lot easier if the fuel is removed as to the weight of the tank. Then you just have to disconnect the fuel and wiring connectors, take the snap ring or the twist type lock off the top of the sender assembly and the whole sender/pump can be wiggle out. Then you just have to disassemble the sender and replace the pump and the strainer while you are at it. Good luck.

Suburban Fuel Pump

Answer 3

I have the exact same problem only I allready changed the fuel pump a year ago! I found this on the web ; chances are it is one of 3 things, a bad fuel pump relay: if it is, it costs about $15 and is located in the "under the hood" fuse box. Look under the fuse box lid for location of the relay. #2 The oil pump pressure switch/sending unit: you can determine this by unplugging the wire connector to the sending unit and jumping the 2 end terminals together it is a 3 wire connector. If the fuel pump starts which is identified by a hum from the tank then it is most likely the oil press/sending unit.#3 The wire connector to the fuel pump itself could also be bad, but this is difficult too because you have to drop the fuel tank to get to it also. I know the oil pressure switch/sending unit sounds unrelated but the wiring circuit to the fuel pump has a branch that is routed through the oil sending unit and it can cause the pump not to operate if it goes bad. The oil sending unit (OSU) is in a difficult location in the back of the engine under the distributor and it takes a deep socket to remove. The fuel pump, if it is actually bad, is a big job especially if you have a full tank of gas. It is usually best to remove the gas before trying to drop the fuel tank. Most tanks nowadays are difficult to get a siphon hose into. The fuel pump I bought cost $180 from an auto parts store and figure 2 or 3 hours of labor just depends on how good/quick they are. There are a few tricks to dropping the tank and there are some fuel line connector tools required but they are not expensive. If you do change the pump, you'll also need to change the fuel filter. After everything I said earlier, you may want to check that the fuel filter is not plugged up...it is a possibility, but I have never seen a plugged up fuel filter. I, of course, buy my gas at reputable places, but if you don't I guess it's reasonable to look at in addition to what I told you. Good Luck Hope this helps!
