Question about 1994 Chevrolet S-10 Blazer

Fuel pump won't pump

Allrite, i have a 1994 s10 chevy blazer 4x4 that i just put a fuel pump into about 6 mts ago. it "went out" again, but this time when i put the warranty pump in, nothing happened. The pump wont kick on at all. The gas gauge reads correctly when the float is moved, so i know the plug is right and working. Now I have no idea where the relay is, and would the ecm have anything to do with it? Which do you think I should try replacing first? any help would be awesome as im getting pissed off. Thank you!

Its a power or ground issue to the pump pcms can be expensive..I would add power from an aftermarket relay to the pump triggered by the ignition switch .Add a fuse and your good to go...check to see if the ground is ok add another if in doubt.

Look for a missing ground strap from the engine to the body or frame. Remember the engine sits on rubber mounts so that ground strap is essential.

I have a 1994 chevy S10 blazer 4x4, it wont start,I replaced the module,fuel pump,plugs,wires,rotar buttom and distributor cap. I can get it to start by putting fuel in intake,but it dies as soon as it...


Have you checked the fuel pressure? There are two different fuel pumps for this vehicle and if you installed the wrong one, for the 4.3 VIN Z instead of the pump for the 4.3 VIN W, Which it sounds like you have a VIN W, It won't start. Also I've seen the harness go bad in the intake that runs the injector. Have you checked for injection pulse at the plug to the injector.

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. :)
