Question about 2001 GMC Jimmy

2 Answers

Front Washer pump wiring. Pump works hot wired, fuses all good. I am trying to figure if it is wiring from engine compartment terminal to behind firewall, or if the switch is bad. Wiper blades work on all settings. I have panel off above brake/gas pedals and have a cluster of 40 wires or so. Any ideas?

You could just mount a momentary push-button type switch on the dash for the washer. Probably less than $5 and drilling a hole instead of $50-$100 for the switch, plus pulling the wheel etc.

Switch most likely. they wear out. The wires your looking at don't. There is a seperate part of the wiper control that works the pump.

What should I check and/or reset on a '94 Camaro to get it to start after a minor collision which deployed the airbags?

If fuel pump issue, check the fuel pump relay. I wasn't sure of engine size, may not make a difference. Check the relay wiring circuits. The pink wire is voltage to load side of relay, fuse protected, goes hot with the key on. You can use a test lite to check for voltage. The control side of relay, left side, needs voltage and ground, that bottom wire is a chassis ground. That top wire is voltage, should be hot with engine cranking, comes from pcm. Hopefully that relay is located behind driver side kick panel, to the left of foot-well. If it isn't located in that area, then, I don't know?

Why want my 93 ford ranger pick up start without pouring gas into the intake fuel pump want come on unless hot wired straight to batt

There is a fuel shut off switch (inertia fuel shut off-opens on impact) in the wiring between the fuel pump relay (in the under-hood fuse/relay box) and the gas tank. It may have opened. I don't know where it is located, it may be behind a kick panel under the dash. You may have to ask someone where it is.

The fuel pump fuse is a 20amp fuse, also in the engine compartment fuse/relay box. This fuse and it's wire is the power feed for the fuel pump relay.

No fuel pressure in efi system

Either the fuel pump is not working, or the filter is totally blocked.
The fuel pump circuit needs checked to see if it's a wiring problem or a failed fuel pump. There will be (probably) a fuel pump fuse in your fuse block, and a fuel pump relay under the hood.
If you check the fuel pump wire for power at the gas tank connector while the engine is cranking over, and there is power there, and the ground for the pump is good, then the pump is not working and will have to be replaced. If you do not have power when cranking, the wiring at the fuel pump relay will have to be checked. Simple relay- has a power feed for the pump at one relay terminal (it is hot at all times), and a fuel pump wire to pump on another terminal (the power out for relay). When relay coil side is energized from a signal from computer, the relay contacts close and power is sent to the pump. The other relay terminal is a ground for the coil side of relay. Pull the relay out and you will see the diagram etched on it. If there is a fifth terminal, that could be a pump prime terminal, or a way to keep the pump running when engine is running through the oil pressure switch. But when cranking the engine, the computer will signal the relay to send power to the pump.

Fuel pump for a 1999 pontiac bonneville will not start after replacing it

Check the fuse for the pump first. You can check that fuse for power when key is on with a test light. Then find the fuel pump relay, probably in relay box under hood, and put your finger lightly on it and listen and feel for it to click when someone turns the key to on.
If relay does click, the problem is likely with the wire to tank from relay, the connector at the tank, or the wire going into the pump.
If relay doesn't click, or if it does and you haven't found problem yet, pull the relay out and with test light grounded to engine, probe all relay terminals for one hot terminal- one will be hot at all times. If no hot terminal, could be fuse link or maxi-fuse that feeds that relay box. If one terminal is hot, have someone be cranking the engine over while you check the other terminals for a second hot terminal. When cranking, two terminals should show power, the main feed for pump, and the signal from computer that energizes relay so power is passed to pump. If two terminals are hot when cranking, try a known good relay. If still no help, problem is with wiring to the pump from relay, or the ground for that relay needs checked.
Post back with what you find. Good luck.

2008 civic where is washer pump fuse

The pump may use same fuse as the wipers. Check for power at the pump connector or hot wire the pump with jumper wires from the battery. If you have power at the pump when the washer button is pressed, likely a bad pump. Or if you hot wired it and the pump works, check for a fuse or switch problem or bad wires.

Looking at the Diagram the power for the washer pump goes from the multi-function switch on column to the pump for domestic vehicles and the power fuse also runs the wipers so if it was the fuse your wipers would not work. The fuse in the PDM in the engine compartment is for a another option so it may or pay not have a fuse. so since the motor works by jumping power to the wire in the engine compartment. Than that leaves a bad switch or a broken connection in the wire between the switch and the bulkhead connector through the firewall.

Windshild washer fluid not squirting in front.

They use same fuse, See if you hear it running when you depress the washer button. If not, check for power at the Dark Blue Wire at the washer pump. If it has power, and the Brown wire is grounded. then the washer pump should work, if it doesnt , replace the pump. The washer pump Dark Blue wire shoul dbe hot and the switch grounds the Brown wire.
