Have you checked for continuity from the fuel pump fuse to the pump do this with the ignition off, you may have a break in the live cable, or take a voltmeter and check voltage at the pump.

I have a 1987 chevy s-10 blazer v6 2.8 fuel injected dat starts up but dies out?


sounds like the fuel pump is not staying on or the ingtion switch doesn't make in the run position ( happens alot to vehicals take have lots of keys hang on the switch) The sparp going away is easy to check with a test light theres a connector on the distrubutor that has a heavy red wire plugged in that goes to the B+ terminal it should be hot with the key in the run position. if it's dead fix the connection at the ingtion switch ( it's on top of the steering collum and all but one wire will be hot with the key on, that one comes hot in start) if it's good the fuel pump is next it has a fuse on the passenger side firewall next to the fuel pump relay. Fuse bad or relay bad or dirty it'll act this way. The start wire entergizes the pump in crank position. then the oil pressure switch takes over and keeps the pump on. theres 3 wires on the oil pressure switch the center wire works the light the left one is fuel pump fuse power and the right one is the fuel pump. the oil switch can go bad and the connection can go bad the wire can fall off or get broken. the wire to the fuel pump may not get all the way to the pump.. You can add power to any wire on the swich with out hurting anything. all of the wires will be hot with it plugged in and running. unplugged two wires are hot with the key on ones the light ( oil Pressure light) the other is the key on power for the pump with oil pressure the switch closes and the pump comes on and it'll be powered right off the starter as it's cranking. If the switch is leaking oil its likly failed too.

Where is fuel pump relay on 92 chevy blazer tb


driver's side under the hood above the brake master cylinder ....should be 2 relays there... it's the outer one... they are identical and you can swap them temporarily to check that your fuel pump relay is working.

2000 S10 4.3L Fuel pump stopped working out of the blue. We Put a new Fuel Pump in, new harnes to fuel pump, new fuel filter, new relay, new fuses in IGN C and ECM B fuses. Still the pump will not turn on....


At the fuel pump relay you should have 1 full time hot wire. 1 hot wire when you turn on the switch. 1 ground, and the other wire goes to the pump. Test the ground to be sure it is good. If so then jump a hot to the one that goes to the pump and see if it runs.If it does then you have a bad relay or ECM. You can swap the relay with another of the same # from tour fuse box to test it.There is also a ground on top of the frame near the filler neck, check it too. Good Luck
