1991 chevy s10 blazer

\015 I have a 1991 chevy s10 blazer 2door 4x4 that the fuel pump stopped working. I have replaced the fuel pump and it still will not start. I replaced the relay as well and still no luck. Can you advise me as to what else it can be. thanks\015 Posted / edited by AnonymousUser on : 23-04-2018

Answers :

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. :)
