I have a 95. Gmc k1500 5.7l 350 4x4 I was redoing my radio decided to crank the truck so it wouldn't die, but it didn't crank. Checked fuses, all fine except the previous owner had a jumper wire set up in...

The toggle switch to the coil may be a anti theft device ( crude but effective ) and the wire to the switch may come from the run circuit on the ignition switch. When the toggle switch is off then there is no power to the coil hence no start. I think this one you will have to spend time tracing out

Fuel pump wiring diagram for 2001 chevy S10

The harness is a dealer part or a scrapyard part. The harness itself for jsut the fuel pump as it is set up by GM- the relay coil has one side hot +12 volts all the time, even when off. The ground side of the coil goes to the 3 bladed oil pressure switch which completes the ground circuit when there is oil pressure This is the tan wire.
There is a wire that comes from the ECU to prime the pump and keep it operating while initially starting. This is usually a white wire.

+12 volts usually is applied at all times at cavity 87 in the relay connector and the wire to the fuel pump is in 87A.

The harness from the dealership will list price at about 2000.00 US, and it will be the entire harness that includes that portion for the fuel pump.

If your pump is not energizing, or not staying energized, the oil pressure switch is likely at fault. By the same token it stays energized all the time unless relay is disconnected.

If you are going to add a switch, the easiest thing to do is gut out an old fuel pump relay and solder to the contact parts and clip the relay coil. This does bypass all auto shutoff. The wire will see some fair current so use 12 gauge or 10 gauge.and keep run as short as possible.

I bought a basket case 95 Iszu pickup, my last issue is the blower motor will not run from the heater switch. The previous owner has run a direct wire from an unkown power source and added a toggle...

Usually, the 12V runs to a resistor pack mounted to the side of the blower motor. When you use the fan select switch, you change the load on the motor and it goes faster or slower. If the resistor pack is defective, that will cause the motor not to run.

You can pull the motor out and attach one side of the battery to the motor +12V side, and attach the ground to the (-) side of the motor to see if it comes on without going through the resistor pack. If it does, replace the resistor pack. If not, replace the blower motor.

The whole toggle thing sounds like a shortcut was taken to avoid fixing the initial problem.

Replaced the climate control and blower wont work

f that just put power to the blower moter and see it it runs if you pull the relay jump a wire across the terminals with it out and add a ground wire to the case of the blower to another spot on the chasis if it still does not run your blower switch may be bad dont worry just run a toggle switch to a good blower moter

Heater fascia lights are on before turning the lihgt stem on

You should get an Haynes repair manual from the autoparts store and a test light and check the wiring to the diagrams. Try unpluging the radio and disconecting any after market looking wires ( marking them where they went) try to repair all of the wiring like it came from the factory and then see whats wrong, maybe a bad light switch? After everythings working good the reinstall the alarm or what you want, one thing at a time, and check the wiring under the steering column covers.

1995 heater blower motor: someone has replaced it before my sister bought it. The problem is it is wired incorrectly, the blower runs only on high continuously no mater where the fan speed switch is...

Since its presently working, don't mess with it yet. You can put a toggle switch in between so you can turn it on and off (you can even mount it under the dash). Get a good wiring diagram and use it to make sense of what you have.(Chilton makes a good diagram book which can sometimes be found in the library) I would not rely on Haynes for this,,, I've seen their diagrams and even with 30yrs in the business, I can't make heads or tails out of their stuff over 90% of the time!!)
Likely, there was a problem in the system to start with and the previous owner opted to just hot wire it rather than repair it. Therefore your problem is not only locating and re-connecting stuff, but figuring out what the other guy either didn't want to fix or couldn't figure out himself! Take your time with this and you can figure it out!!! Though this may not qualify as a "solution" it will help get you pointed in the right direction!
Good luck
