Question about 1987 Chevrolet Blazer
I replaced the fuel pump in my 1987 K5 Blazer. I connected the pump to the port on the driver side and cannot find the location to ground the pump. The wire leads from the pump and has a loop connection.
Attach it to any metal part of the body . Clean the area first to ensure a good connection. Use a small self tapper screw

chack and see if your security light is staying on if so then security is shutting down fire to injectors.
are you gettting spark? pcm needs to see a signal from cam sensor to fire injectors. also when you first cut key on you should see the injectors give an initial shot of fuel

The 92 S-10 I had did not have an emergency shut off.Yours may, or may not have, depending on what previous owners may have done to the vehicle.
You need to get a factory service manual (not Haines or Motors or Chilton) to diagnose the problem, Most larger repository libraries have them. The FSM's have complete troubleshooting guides.

first ... look in the fuse panel.. in the engine compartment near the battery for the fuel pump relay.... replace that... if still no sound from the fuel pump it has likely failed. use a meter to test for voltage at the fuel pump.... or use a car battery to apply voltage to the fuel pump directly... if it starts up the issue is elsewhere. to replace the fuel pump you will likely need to drop the fuel tank.

under the hood...above/slightly to side of passanger side valve cover...should have grey plastic locking "key" on the face of it
