Fuel pump switch,wiring

1992 silverado v6. I found my truck engine covered with insulation from the hood, and a bunch of wires chewed apart. I got the wires fixed but then the engine would turn over but not start. I found the wires in the fuel pump relay area to be chewed up. I removed the switch and got the wires fixed. Before I got it all back together I got sidetracked and had some extensive surgery, Going back to the chevy job I found I had forgotten where the switch and two of the wires were supposed to be attached. one wire is black and the other white. .

    your photo missed the spot. I am attempting to send a photo. There is a cover over the switch. It is at the top of the fire wall at left looking from front of vehicle.

Wiring diagram delphi sa10001


Did you check the fuel pump relay in the fuse center under the hood? Maybe you blew the relay and really didn't need to replace the pump. Did you recheck all the wired connections with a DVOM? Never ever replace anything as important as a fuel pump with out double checking all connection and checking for voltage before putting it all back together. Hopefully you didn't put the gas tank back in yet. Oh and you can swap the relay with one of the others sitting next to it i the fuse center, just remember to switch it back when you're done.

Wiring diagram for 1987 chevy silverado 10 free downloands


Sorry, I don't have good enough wiring diagram for your model year?
Check for battery junction block, under the hood, one of the positive battery cables should go to it, see if there is a bunch of fusible links, check them. Use a testlight on out put side of link, check for voltage. If there is a handful of links, sorry, I don't know which one. Maybe you will get lucky and the first one you check will be the faulty one, where applicable. I don't usually get that lucky. If you make a hole in wire insulation, use finger nail polish or something to cover the holes.
I thought about using jumper wire for B+ to ecm B fuse for testing. I don't want to suggest anything that might cause you more problems, you need to fix it properly.

1988 chev silverado v6 no power going to the fuel pump. i checked for power where it plugs into the fuel pump on top of the tank and i got no power. what actions can i take to get power


check all ur fuses for continuity first, then u can also try to swap out ur fuel pump relay with another relay that looks jus like it, be sure to use a relay like for ur horn or ac relay something that wont affect necessary or direct engine circuits like for ex. an ecm fuse or bcm fuse. if fuses r good an swappin relays wont work, next is to trace bak from fuel pump ur wires an possibly keep back probing to see if u have a broken wire from relay box to pump . good luck hope this was helpful . in ur fusebox ur fuelpump fuse should b labeled or easily found in fuse box legend, most likely on bak of fusebox cover....

I don't know if th fuel pump is bad we just replaced two months ago or if it. A relay switch.were is the relay located?


Hello: The fuel pump relay is in the under hood fuse box, The location should be printed on the underside of the fuse box cover. The box should be on the drivers side under the hood. One other thing it could be is burnt/heated terminals on the connector from the truck wiring to the fuel pump harness. Also check the fuse for the fuel pump (20amp) in the same fuse box.

Where is the fuel pump fuse in the engine compartment?


It is not a fuse, It is a relay.
There is a single wire test lead under the hood, usually gray in wire color. Apply power there to test

1992 Geo Prizm wont start


It could very well be your problem. What you have to do is unwrap the bundle and trace that wire back until you find where it comes from or it stops looking melted part way through the bundle then look at all the other wires close to that spot for burnt spots or insulation worn off and cover them with electrical tape. Cut the burnt wire off and replace it with one the same size,making sure you tape up the splice, and run it back to the engine where it started.
If it goes back to a fuse or switch check them out to make sure they are good. A fuse could have burned out when the wire overheated or a switch could be bad and made it burn. Hope this helps.

Need location of fuel pump on a 1992 BMW 525i straight six engine


The fuel pump is located under the back seat on the passenger side. You will find an access cover and will need to remove the screws. You should be able to listen for the pump while someone cranks the car. Also I believe there is a large green w/ blue trace wire and an equally large brown wire at the connector. Check for battery voltage across the two wires. The fuse for the pump should be in the fuse panel under the hood.

FUEL PUMP FOR CHEVY SILVERADO


fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?

Lift the hood. Just below the screen, opposite side from battery, you'll see a plastic cover shielding the engine management, abs control box etc. If you search around there after removing the shield/ cover you will find a relay with a fuse plugged into the top of it. This is the pump / system relay.
