You have a bad fuel sending unit bracket, on top of your fuel tank. This is a VERY common issue. Frop the tank down, you will see the problem. Replace the bracket, and you will be good to go.

88 toyota pick up v6 keeps blowing efi fuse


you may have a short of some kind, when a fuse blows repeatedly it is no good just replacing, you are being told that something is wrong with the equipment.
You will almost certainly have to visit a technician for a diagnosis. It is unlikely to be something that an inexperienced end user can sort out I am afraid.

GOOD LUCK

I have a problem with the 15 amp efi fuse blowing on my 2001 toyota camry. As well as the 15 amp gauge fuse blowing


if there is no shorts, rig a amp meter in series in place of the fuse, if it reads around twelve or more amps some thing else may be wired into the circuit , if the reading is very high there may be a short to earth some ware.

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.

Efi fuse blows when car strts wher is the efi located


NO YEAR stated (old post)
there is no EFI fuse. sorry,
the ECU has 3 fuses.
FI, Dome, and IG-coil
all 3 run the ECU.
i do know what you ment.
but knowing the correct name makes reading the FSM better.
my guess 2 is you lost the fuse box cover and cant read the names.
guessing year at 91 -95

the ECU fuse blows page. is here
http://www.fixkick.com/power-elect/blows-fuse.html

top reasons.
ECU bad CAPS
shorting fuel pump (they pull 4amps normal) if 10amps or
more they blow the fuse and or causes the ECU to click relays
like mad.

EFI fuse keeps blowing in 1998 Camry


There is only ONE reson why a fuse blows: Something is overloading the circuit and drawing more amperage than the fuse is designed to handle. This is what is known as an "overload" or a "short circuit".

Plesase read the following two articles:
Where's the fuse?
What else could be wrong?

If after reading these two articles, you think you would like to try your hand at tracking this down and fixing it yourself, and you are sure you have the correct equipment (as listed in the articles), let me know and I will help walk you through it.

1987 Nissan Stanza

you will need a repair manual
http://www.nicoclub.com/service-manual?fsm=Stanza/Sanza_1989_FSM

comes up as having both efi or carby what has yours got

if carby its a lot easier to bypass the faults to get it to run

will assume its EFI

EFI will be a problem if any wires have shorted
may have blow the large fuses in the engine bay giving power to the car


for both carby and EFI
pull the light fuses and relays out

check all fuses and relays in the engine bay cluster are not popped

starter relay and EFI ecu fuse are in the engine bay cluster

if the motor turns over
the fuel pump must be pumping fuel with pressure required to run the car to get fuel to the carby /or fuel rail and injectors
if you get that
only have to worry about spark
have you got a good coil arc and spark to all plugs

1990 toyota pickup 3.0 v6,engine will not start,keep blowing efi fuse


You need to look for a short in the engine harness, anywhere that the harness rubs on engine componets etc. In the past 30 years of car work this is where the problem most often occurs.
