SOURCE: 96 Suburban v8/7.4L/454 K2500, Knocking Noise??

sound like an internal engine problem. either one or more of the pistons has "piston slap" and that knocking will diminish as the engine warms up or possibly a rod bearing is worn out. have a tech do a manual oil pressure test to make sure the oil pump and main bearings are ok. piston slap or knock that decreases when the engine warms up is not that serious, but a rod bearing knock or possible oil pump failure should be taken care of asap.

How do I jump a fuel pump relay of a 1988 GMC K2500 with a 5.7L to get power to a sending unit from a 1998 GMC C1500 with a 5.0L V8?


Not sure that we are thinking of the same thing. The wires to the gas tank operate the fuel pump and the fuel gauge. The relay is used to send power to the pump and you should not have to do anything to it to get power down the wire to the pump. When you turn on the key, the relay closes and power goes to the in tank fuel pump.

92 chev 454 when u hit the gas it starts to sputter now it wont start


The reason it worked is because when you banged your tank the bushings in your feul pump started workin. It is actually a old trick when people would break down due to a bad fuel pump. As you can imagine though that will stop to. Just a case of replacing fuel pump.

Fuel pump push rod


I would use something like the fuel pump listed here, this is a good performance fuel pump that will be able to feed that 454 engine, it comes with a fuel pressure regulator and you can either use a fuel gauge to set the fuel pressure or install an in-line fuel gauge near the carburetor to easily check and monitor the fuel pressure, and set the fuel pressure regulator for 7psi of fuel pressure, and any more fuel pressure than that and the fuel could be pushed past the needle and seat inside the carburetor.

Replace fuel pump 1984 gmc k3500i can't get the pump to seat properly


Parts needed:
1 Can P.B. Blaster
1 Fuel Pump
1 Fuel pump strainer : (some pumps come with this already if not you will have to purchase, do NOT reuse the old one)
1 Fuel Filter : every time I replace a pump, I always replace this part because it is the number one reason for pump failure. FYI its recommended replacement is every 3 oil changes)
1 Multi-pack of fuel hose connectors
***optional 1 Fuel gauge sending unit: (not needed but while you are in there u might as well replace this especially if you have issues with your fuel gauge

On the 1984 gmc. the fuel pump is located within the tank. I recommend syphoning all fuel from the tank prior to dropping it. Also you may want to raise the vehicle on jack stands just to make your life a little easier. There will be two straps holding it in place prior to doing anything, I would soak the threads of the bolts real good with some P.B. Blaster multiple times before removal. You will have to disconnect the fill neck hose, (given the amount of room) it is usually easier to loosen it at your fuel door. MAKE SURE that the fuel pump wire harness IS DISCONNECTED from the top of the pump assy. On some of the models that I have worked on there may be a cross-member that will have to be removed due to it being in the way, if so soak those bolts with the P.B Blaster as well. Go ahead and remove the nuts from the fuel tank straps, you will have to bend the strap back just a little bit to get the tank to fall, when it does disconnect the fuel lines from the assy and make sure all other lines connected to the tank are removed from the tank. You should be able to slide the tank out from under the vehicle. Although there is not too much to it, just labor intensive, your best bet is getting a Haynes manual to walk you through the process step by step if you have never pulled a fuel tank. The manual usually sells for about 15.00 at any local parts store. Also a second set of hands will make this job a lot easier. I hope that I have answered your question to its fullest.

My 1996 Gmc K2500 with a 7.4l is miss firing. runs good till it warms up, then the problem starts. I have no codes in the computer. new fuel filter, spark plugs, air filter


Very good chance that it's bad fuel injectors and/or fuel pressure regulator. Very common with the 96-2000 L29 motor (Vortec 7.4L)
Replace with better injectors, the OEM ones are NOT WORTH cleaning. Go to http://www.fullsizechevy.com/forums/general-discussion/technical-maintenance/213662-96-99-454-vortec-owners.html

89 GMC C3500 454/w FI will not start.


check you fuses inside and under the hood frist.then see if you have power to your pump. you can try hitting the bottom of the gas tank. some times it will make your pump work. you can take your gas cap off and see if you can hear the fuel pump work . good luck
