Where is the fuel injector fuse located on a 1993 s10 blazer

I have a 93 s10 blazer with the 4.3 ive determined there is plenty of fuel pressure and spark the fuel relay however will not ingage when key is cycled. ive replaced it and still nothing. i bypassed it and got the pump to run but still will not fire without starting fluid or stay running im afraid it may be a fuse (which i can not locate) or the ecm itself may be bad

SOURCE: Fuel Pressure Relay location

Hello, There is no fuel pressure relay. If you mean fuel pump relay, you can find this by opening hood, look towards driver's area, on the firewall just below the cowl vents you should see a relay with 5 wires going to it.

SOURCE: fuel problems cant get car to start

FUSE SHOULD BE UNDER THE DASHBOARD ON THE DRIVERS' SIDE. WHEN YOU CHANGED THE PUMP, YOU NEED TO CHANGE THE FUEL FILTER AS WELL TO MAINTAIN THE WARANTY. I WOULD CHANGE THE FUSE AND FILTER. HOPE THIS HELPS. LET ME KNOW HOW YOUR DOING. BEST OF LUCK

SOURCE: 1987 chevy s10 2.5l tbi will not start. changed

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

There is a injector spider under the intake,this,or the fuel pressure regulator could be the problem,so you might just check this out.

1993 s10 4.3 starts fine, while idling it dies. sometimes i have a hard time restarting. the blazer died a couple of times while driving.fuel pump is good, tuned up, remanuf. injectors 1 yr ago,engine lite...


only half way there if you have a tbi check the crank sensor/ cam sensor that is the first line of business on that truck if the crankshaft sensor fails the truck stops dead when you wait a few minutes the sensor re energizes and the truck will work again for a bit antiknock can cause similer problems but not while the truck is running

Sounds like it needs a new fuel pump. Get a Fuel Pressure Gauge and check it make sure it up to the Specs,What I think is about 35 to 40 psi without looking in my book. Also you would want to make sure the fuel filter was changed, Your getting spark and fuel, But You stated your able to start it with starting fluid so I would say it must be a fuel pump problem.. I hope that help you out. If not get back to me and we can try some more trouble shooting. Take Care, Bear
