1997 blazer . Have to prime to start changed fuel regulator and oil pressure switch ( fuel pump relay in oil pressure switch) same problem


Sounds like your pump not working. Can you hear it buzz on for couple of seconds when key is turned to on?
A fuel pressure test will verify if pump is working up to par.

Is there a reset button on this fuel pump


CHEVY DOESN'T USE A FUEL PUMP RESET/CUTOFF SWITCH, FORDS USE THIS FEATURE, ON A CHEVY IT IS DONE WITH THE OIL PRESSURE CUTOFF SWITCH, SO IF U LOOSE OIL PRESSURE THE FUEL PUMP CUTS OFF, THIS OIL PRESSURE FUEL PUMP CUTOFF SWITCH AND IT'S WIRING ARE NEAR THE OIL FUILTER UNDER THE TRUCK.

Fuel shut off switch , where is it


Ford had a shut off switch only. It is a saftey design Fors had for decades and no other Car maker has this option as of yet
Yours will have a fuel pump fuse, a relay to the pump. an oil sensor that is runs the fuel pump only upon starting up the engine and shuts off upon when the engine reaches normal oil pressure. When the sensor shuts off the fuel pump relay takes over until the engine is shut off. When you turn the key to the on position you will hear the fuel pump working inside the fuel tank. No need to turn the key to the start position only to the on position. If the pump is not working you have either a bad fuel pump or a oil pressure sensor. If you do hear it pumping for 5 seconds the engine should fire and die out telling you the relay or pump is bad

I have a 1997 Chevy Blazer that has oil, but no pressure


There's something you can do to check if the oil pump is still working screw off the oil filter and start it only for a few seconds if oil shoots out the pump is working if it doesn't the pump could be clogged or it lose prime if it's working check the wire going to the oil pressure switch may be broken.

Where is fuel relay


The fuel pump relay is only for the fuel pump priming when you turn on the key. After the vehicle starts the oil pressure switch takes over and runs the pump. If the pump is shutting off after the motor is running the oil pressure swith is probably bad. Let me know if i can help you further.

Fuel pump 2000 chevy blazer


Check your connections. did you run the fuel pump wiring under the drivers side door sash like GM did?.. if so check for nicks in the wire or bending or cracks.. this happens.. happened to me. check your fuel pressure. 40 dollar part at an auto store. If its below 59 PSI it wont work. And blazers are very intolerable to low fuel pressure. Also try taking the negative post off your battery for a little while and then putting it back on and if you can get it started again drive around (if its safe and running decent) for at least 30 minutes to get your car computer system acclimated to a new functioning part. Did you check the fuel filter?. rule of thumb when a pump goes change the filter its always the last thing people expect because we all jump to catastrophic engine failure at the first no start moment. lol.
Make sure that all your ducks are in get my drift.. Air oxygen fuel thats the mixture you need to check all those vital parts. before pulling your head off.
