This is an unfortunatly common problem with this vehicle, if my hypothesis is correct. Try this: disconnect the wiring connector going to the fuel tank, under the bed. Replace the fuse and crank the engine. If the fuse does not blow, then the power wire going to the fuel tank sending unit is shorted out to ground. I change about 15-20 fuel sending units a year for this exact same issue. Replace the fuel tank sending unit if the fuse does not blow. When you get it out, you will see the cause of the short, rust at the connection on top of the sending unit. Hope this helps.

SOURCE: 1992 toyota pickup , blowing efi 15 amp fuse in

Check the circuit opening relay, located behind glove box or kick panel on right.
Look for signs of corrosion, this fuse only powers the fuel pump and the engine ecu

SOURCE: 1994 TOYOTA PICKUP A/C FUSE WHERE IS THIS LOCATED

Mine's in a different location than the previous post ... I've got a '94 Xtra Cab from Japan (pre-Tacoma). Pull the glove box ... 3 screws across the
top and then a screw and bolt below. There's a small covered fuse box for a/c and heater on passenger side about where the upper door hinge
attaches to body.

15amp efi fuse blows


It is not related to car being cool down , I think you are having ignition switch on . The EFI fuse goes directly to the contact switchin the EFI relay. Maybe try removing the EFI relay, turn the ignition to ON, and see if the fuse blows.
Doing this, the car won't start, but it might give you a clue as to where the short circuit is located. ... Check the fuse/relay box next to the driver side fender in the engine compartment.

93 geo prism fuel pump fuse location?


why not just use voltmeter, to check all fuses for hot both sides? key on. (need a video?)_
why not post symptoms then ask a question.?
must we send for ever looking for that which doesnt exist.?
and did you know there is more than one engine?
and both are wired different with different EFI systems?/
4A or 7A? engine, its a toyota corolla btw.


eg:
pump pressure is zero. (gages)
i check relay, the FP relay is closed.
i check the relay input and no 12vd.
sure bad fues, is there is one.
but on many cars , lots of other things go dead too. with this fuse.

ill now guess 4a engine with coin toss. vin code 6, engine,
i open glove box. and see the book the opr guide (yes buy one)
and turn to fuse page.
or login to alldata.com and stop guessing.
i look under prizm and corolla, 93 for best clues. (big hint, wink)


this EFI has 2 relays, one is the main relay,
other is fuel pump
the main sends power to the pump relay.
so there are 2 fuses,
one is marked
EFI-Fhtr fuse
and
IG coil. fuse

the main relay drops out of the transmission A/T is not in park or netral.
if manual stick car, the clutch switch does the same

alldata.com

look up your car, your trans, your engine.
and see the schematics.

What's is the function the efi fuse


It supplies the EFI Main relay, which in turn powers the fuel pump, ignition switch, and starter relay. In addition it powers the ECM computer, so that if you wish to clear a trouble code from there, you pull the EFI fuse for 30 sec. See here p177 http://www.turboninjas.com/camry/eg1.pdf good luck

Fuel pump not starting


Below is the location of what I believe you are looking for. I also included a picture of the location of the terminals for the FP & +B on that connector. Below that picture is the location of the fuse panel that the EFI fuse and relay are located. Below that picture is a diagram of the fuse layout with descriptions so you can locate them in that fuse panel. Now there is also an opening circuit relay that the FP circuit goes through. The EFI relay also depends on this relay. In the last picture is the location of that relay. Now exactly sure if this is what you are looking for or what problems you are having but I believe this is the information you are looking for.

Why does my efi fuse keeps popping 1999 chevy prizm


Pull the EFI relay, replace the fuse, and see if it blows when you turn the key on. If it does not turn the key off, reinstall the EFI relay and remove the circuit opening relay/fuel pump relay. Turn the key on. If the fuse blows than we know the problem is One of the O2 sensors, the IAC, the purge solenoid, or the ECM You can unplug the O2 sensors, iac, and purge solenoid. Replace the fuse, turn the key on, and plug them in one at a time until the fuse blows. Replace that component. If the fuse blows with those unplugged than its probaly the wiring and possibly the ECM. let me know what you find and I'll help you more if needed.

Where is the fuse for the fuel pump


There's a relay and a fuse both but if the fuse is blown the pump might be bad as if the fuse is'nt bad the fuel pump probly is. The circuit opening relay is behind the glove box it's powered by the EFI relay in the underhood fuse box and the fuse is the EFI fuse in the underhood fuse relay box

1995 toyota camery is there a fuse or relay for the fuel pump


The fuel pump doesn't have a single designated fuse, it gets electrical input voltage from several sources, the fuses tart you need to check are the 7.5A ignition fuse, the 15A EFI, the 15A starter. There are two relays that are involved, the circuit opening relay located behind the glove box and the EFI main relay located in the fuse box under the hood, the most common problem when there is no fuel pressure is the fuel pump, check all the fuses and substitute the two relays to see if it solves the problem.
