90 lesabre limited Fuel pump fuse blows every time I start the car It's a 20a fuse, I'm not even sure if it's a final pump fuse I can't find any diagrams showing what is what. Right side of dash


20 AMP is a big fuse, I would say its the fuse to the motor check this web site http://www.beijing-fanyi.com/1990/1990-buick-lesabre-wiring-diagrams

Fuse s under hood keeps blowing. It is the inj/coil fuse


Try jumping the starter with the key on. If it doesn't blow. Check the start wire for chafing and grounding out. You can pull the starter relay, Try to start it, see if it blows,yes, it is between the fuse panel and fuel pump. no. Put it in and pull the fuel pump relay. Start it. If it blows, then it is some where between the fuse panel and starter. If you have one of those intelligent fuse panels, it could be that also. You can have the codes read for it. But it takes a scanner, not a code reader.

1999 Toyota camry. Automatic trans. Blows fuel pump fuse when shifting into drive. Checked wiring. What else can it be?


Robert: According to CarGurus.com: " I agree it may not be your fuel pump. You can access the pump under your back seat, underneath the cloth under there. You will iummediately see the plug and the screws to open the little hatch. My 1986 Camry also has a problem with not getting any fuel and thought it was the fuel pump. turns out I keep blowing my efi fuse so i unplug the power wires to the fuel pump and it still keeps blowing the 51a efi fuse. So we have narrowed it down to being an electrical problem. We think it is a shortage or a bad relay. So do not instantly run out and think it is your fuel pump. If you are blowing fuses unplug the power wires to the fuel pump and try to crank the car if the fuse still blows then it is not a bad pump, if it does not blow then there is a shortage in the wires in your fuel pump. Hope this helps I will let you know exactly what the elctrical problem is in my car once we do a complete run down."

2004 ford explorer when you turn the switch on the fuel pump fuse blows . i un pluged fuel pump it still blows . i went and un pluged fuel control module and it doest blow


Unplugging the fuel control relay or module will ensure no current is entering the wire heading towards the fuel pump. The likelihood is there is a short circuit somewhere along that part of the circuit though it is possible the relay could be faulty.

Ideally, with the aid of a circuit diagram, the wire should be traced from the source at the fuel pump module along its length until the fault is discovered. There is intelligent equipment available that can locate short circuits.

Fuel pump fuse blow when I turn the ignition on and cranks but no start, why?


Unplug the connector at the fuel pump. Install a new fuel pump fuse. Try to start the car. Does the fuse blow? If not that the problem is probably a bad fuel pump. If the fuse does blow with the pump disconnected than you need to look for a short in the power supply to the fuel pump.

Keeps blowing fuel pump fuse. Why?


This normally happens due to short in the wirings.Or if someone has connected a stereo or some other electrical contrivance to the wiring harness (bundle), either under the dash or under the hood.To confirm this unplug the fuel pump wiring connections and insert new fuse.Then start the car and see,if still the fuse blows then its a short in wiring.But if the fuse does not blows then its faulty fuel pump relay or faulty fuel pump itself.So first replace the fuel pump relay and see,if the fuel still blows then its faulty fuel pump.But if the fuse not blowing then relay was the faulty part.The fuel pump relay located on the fuse box under the hood.---------This troubleshooting tips will help you locate the fault and solve it.-------Thanks.Helpmech.

Main Fuel Pump


Fuses mean short somewhere.Fuse is always live it feeds relay but in tank pump [ fuse#4or#6 i forget anyway visa versa ] is not live until this.Relay clicks once when key tuned to on and once more when key turned to crank engine it is under dash by glove box and loud enough for someone with ear at this spot to hear.In tank pump should not be live until engine starts to crank.
