94 chevy s10 blowing fuse

It needs retiring, how many million miles has it done? ;>)

Check the wires around the fuse boxes and the ECM. Look for wires that have rubbed through to the chassis.

A flat battery is the most obvious. Dash Lights take no power to light up, but starting needs AMPS.

Turn on the headlights, turn the key, do the headlights stay bright? If they do, the battery is okay. If they dim, it isn't.

Put the vehicle on a high end scan tool. It will tell you where the fault is.

need a meter and test for a short

A bad relay or a shorted wire. Pull the relay, turn the ignition on. Fuse pops, bad wire from the ignition switch to the fuse/relay panel. If it doesn't, swap relays in the panel. Turn it on, if the fuse pops, bad wire to the ECM or the ECM has shorted internally. If it doesn't pop, replace the relay.

you call the fixer.

Fuse under the right passenger dash. Fifth up on the right (blue 15 amp). It is called BCK/UP/STOP. All the same symptoms short in wiring harness for the trailer package caused the windows not to function, the right rear turn signal had no power, and the key was stuck in the ignition.

what does this fuse go to? What number is the fuse?

the dash sound's like a fuse, check the fuse box under the hood and in the door jamb on the side of the dash, also check your fuel filter and fuel pump, im betting on the pump because i have a 2001 chevy blazer that has had two replaced and it has 233000km on it!

i have a 98 chevy s10 zr2 and we changed the fuel pump and aint gettin no power to the fuel pump checked the fuses and relay under the hood no power and the gauges inside are not working other than lightin up.are there another fuse link some where

you should have 2 ecm fuses under the dash in the fuse box check these one of them is probably blown I have had 2 s10 that blow this fuse occasionally
