Begin by spraying all attachment bolts with a good solvent, then remove fill neck at the top. (where you put gas in) Disconnect harness, remove attachment bolts part way, support tank with a jack. disconnect one side and let the tank come down a bit, then disconnect fuel and vent lines etc. Label them so you know where to put them back. (Many have plastic couplers for which parts stores sell a tool to remove them without damage...have that tool on hand before you begin) Remove other fastener and lower tank to the ground. It's best to have the tank nearly empty to begin, but if not, it really isn't too bad coming down. Definitely empty it and clean the insides out before putting it back up though.The pump itself is held in either by a collar that is turned and locks in place or a "c" clip around the perimeter. Make sure that you clean the "o" ring under the mount plate and put it back on re-assembly. Use care when removing and re-installing pump that you do not damage the float arm or you will have a gas gauge problem later.
No smoking within at least fifty feet and no electric power tools or drop lights. Gasoline is relatively safe to work around as long as there are no sparks or open flames anywhere nearby. If they are, it is very dangerous.

Wont start unless you pour gas down throutle body on 2001 chevy blazer


You'll need to see if your fuel pump is providing fuel pressure. First test would be to take off fuel cap, listen through filler tube as someone turns ignition on for a few seconds, then off for a few seconds. Repeat a few times you should hear the fuel pump start then stop as it builds pressure.

No noise, then test voltage coming to pump if yes, 12 volts, replace fuel pump. Test ground also before replacing pump.

I would expect it to be this as the computer wouldn't allow the vehicle to run with fuel being poured into the engine otherwise.

If it's pumping, you will need to do pressure testing to determine if it pumps enough, or just replace it as either just the pump, or the complete pump assembly that drops into the tank rather easily.

Pumps are available at dealers OEM, discount auto parts stores, and I've had good luck with pumps that I've bought on eBay.



good luck

How do i get to the fuel pump on a 1997 s10 blazer


Unless there is an access panel inside the vehicle above the fuel pump, you will have to remove the fuel tank in order to access the pump. Do not forget to replace the fuel filter. Partially clogged fuel filter is one of the causes of a failed fuel pump.

Chevy Blazer won't start; fuel pump needs replacing


Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.

HELP! HELP! SOMEONE PLEASE ! 2001 chevy blazer fuel problems


I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.
