Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)

SOURCE: 95 chevy blazer tank removal

Park the vehicle in a place where you’ll have plenty of room to work. If you have access to a lift, that would be great.
Relieve any fuel pressure by removing the fuel cap. Disconnect the negative battery terminal. Pre soaking any required bolts/nuts with WD-40 prior to the job will help also. There are 3 lines and 2 electrical connectors to be removed from the fuel pump, and the filler and vent hoses that need to be removed from the back of the tank. There was also a small hose on the front part of the tank that needs to be removed, but we didn’t see it until we actually started lowering the tank. Just remember where everything hooks back up. Label the lines, if needed take picture with your cell phone.

Start by removing the skid plate, Once the skid plate is off, you’ll have access to the straps that hold the fuel tank on. The forward ******** the Blazer will pretty be rusted and not very stout. It's basically formed as a strap that ended in a threaded bolt and in most will end up breaking trying to remove it. Supported the tank with a floor jack with a transmission removal assembly on it.

You easily fixed the broken strap problem by welding a bolt to the strap. Once all the straps were loose, lower the tank just enough to get better access to the lines and connectors leading to the fuel pump. There is not much room to get in there on a Blazer. 
Once the tank is off, it’s a good time to look around in that area to see if there are any other problems that may need to be addressed.

If you are going to replace the fuel pump here's how to do it. Before removing the fuel pump, be sure to clean off all the junk that has collected around it. 
Replacing the float and sending unit is fairly simple. Just pay attention to how the old parts are removed, and install the new parts in reverse order. Be sure to get the wiring routed correctly and install the new seal that comes with the kit. The sock filter on the bottom of the pump was just a little bit clogged, so we made a trip to the auto parts store to get a new one. Luckily they had one that would match up. 
While we had the tank off, siphoned what fuel was in there and cleaned out the tank really well. 

The installation is basically just a reverse of the removal. Be prepared to take quite a bit of time for this project. It took much longer that I expected. Somewhere around 6-7 hours, but that’s including several little problems, getting propane for BBQ lunch, and making a trip to the parts store for a new sock filter for the bottom of the pump. And Mom and dad showing up.

Good luck and hope this help

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.

Cant locate my fuel injector in my 95 chevy blazer


Your '95 blazer does not have fuel injectors as such. Fuel delivery is accomplished by way of a " throttlebody" injection system. This unit is mistaken for a carbuerator but is systematically controlled through several electrical connections by the on board computer.

Where is the fuel pump relay located in 95 chevy blazer s-10?


The fuel pump relay in my blazer is located in the rear of the glove box which means you have to clean out all of the maps and other junk to get to it. There is a plastic cover that has to be removed to expose the relay which is the right side of the two present.
You can tell if it is operating when you turn the ignition key to "ON", the relay will click and you should hear a humming sound as the fuel pump energizes.

The fuel pump may be running but it may not be providing enough fuel pressure. Have the fuel pressure checked at the fuel rail and if it is not to specification, replace the fuel pump.
