yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

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.

SOURCE: 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.

I have a 2001 Chevy Blazer, I have a full gas tank that's leaking fuel. I want to pump out the gas by using the fuel pump. Where can I hook up a positive feed that's easily accessable to turn on...


The easiest (and least invasive) way to do that would be to remove the fuel pump relay and jumper the connections to make the fuel pump run. One connector at the fuel pump relay should be hot at all times (without the key on). Jumper this connector to the connector that goes to the fuel pump. The connector that goes to the fuel pump will be the connector that is opposite DIAGONALLY from the wire that is hot at all times.

The fuel pump relay is located in the underhood fuse block mounted on the left fender apron. The diagram inside the fuse box lid will show you which one it is.

I need to know how to check the fuel pump relay. If it is good, my fuel pump is bad. Can I by-pass the internal gas tank fuel pump and put an external one on. This is for a 2001 chevy blazer. Is it...


no bypass. There is no switch (Fords only) there are several relays that are th esame, you can swap it with the horn relay. You should be able to hear the relay turn the pump on for 2 seconds when you turn the key on. Sometimes you can give the bottom of the fuel tank a rap and it will get pump going again for a short time, If that gets it going, replace the pump ASAP.
