What does the "fuel sol" abbreviation mean in the fuse block under the hood?

fuel solenoid, or on gas engines fuel pump relay. Here is a guide to help check the fuses with the fuse box location and ID below.

fuse # 14 is good. I push it in the fuse box where it belongs, but there is no function. I cannot see the back of the fuse box to see what is going on.

there is no fuse 14 listed here is a picture of what fuse is which.

Is there anything to interupt power supply to heat/air control on 92 chevy 1500 other than the 25 amp fuse in the fuse panel ? I have replaced the 25 amp fuse and tried 3 used control modules but none of those show that they are recieving power. None of the control units will even light up much less run the blower.

Ignition switch and fan speed switch. Blower resistor and relay. Here is the fuse panel in the diagrams below.

There is also a power lead that runs off the battery junction block in the engine compartment. I believe it is fusible wire that could have melted. If that is the case, be sure to only use fuse wire to replace it.

My headlights work, but my taillights do not and neither do my dash lights, but all of my other electrical systems are just fine including brake lights, backup lights, turn signals, interior lights, radio, power windows and locks and heater/ac. We have checked all of the fuses in the box under the steering wheel and they are all fine. Is there another location under the hood of fuses that we can check or do you have any ideas of why I am having this problem? It just started all of a sudden today.

Hey Retrorocket,

It sounds like you have a headlight switch that is out, but here is a wiring diagram and the fuse panel diagram to help with the testing, there is no other fuse panel besides the one under the dash.

I have a no start issue, truck cracks fine, has spark, but the fuel injectors are not getting power, i have been having an issue figuring it out and the location of fuses and relays.

Good afternoon,

I attached the diagram of the fuse box for you to view. The injectors are fed by a fuse. The other side goes to the ECM for toggling.

You need a test light or voltmeter to check for voltage at the fuses panels.

https://www.2carpros.com/articles/how-to-check-a-car-fuse

Let me know when you are ready for testing.

Roy

Where is the A/C Heater fuse located?

Here are the fuse panel diagrams for both C and K trucks along with a guide to help you test the fuses. The fuse panel is under the dash on the drivers side

I have the truck listed above half ton. one morning when I went to go start my truck I turn my key the starter engaged engine started then all the sudden it shuts off and smoke was coming out of underneath my hood. when I want to go check it out the power distribution block wires were shorting out and one of the red inline fuse from the power block caught on fire ! The power wire that got caught on fire is the one that runs to my convenience block it's a thick red wire. my question is, that the wire that goes to my ignition switch? I ended up cutting that red wire from the power junction block and I check continuity from the wire. I cut to a ground and it showed that there was continuity when it's supposed to be a power source from the junction block. does that mean I have a short to the frame before it gets to the ignition switch ? I really don't have any idea.

Good morning,

Can you post a picture of the damage for me to view?

I attached a wiring diagram of the ignition switch as well as the fuse block.

Roy

This red wire on power block  was the one that actually literally caught on fire! luckily I put it out before it got out of control. There was a inline fuse that I cut out that red wire. Now I put a continuity tester probe on that red wire that was shorting out that I had cut out  from the power junction block (the red wire  in this picture that runs to the steering column) and the other end of the probe  to a ground on the firewall and the probe showed there was continuity from the ground to the that red wire. now my question, is there supposed to be continuity  or does that mean that there is a short along that wire to ground somewhere? I hope I make sense to you.

That wire is shorted to ground. You need to trace the route of that wire.

What are these symbols on diagram?

What symbols?

Roy

The symbols where the red wire goes through.

Yes i have a 1988 chevy silverado c1500 and my headlights taillights and dome light quit and do not have any power coming out of the fuse box what might the problem be?

Hello,

There are fusible links down by the starter check to see if you can pull on them. Here is a guide so you can check for power and the headlight wiring diagrams so you can see how the system works.
