SOURCE: 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.

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

How do I fix code 13 engine speed sensor Above 1000 rpm


Clearing the codes is simple that is done by removing the fuse of the EFI from junction box 2 for 10 seconds. Make sure to remove the jumper wire and switch the key off before clearing the codes.

Here are some common Lexus vehicles 1990-1995 codes:

Code 12 and Code 13 Rpm signal circuit fault
Code 14 Igniter signal circuit fault
Code 16 ECT control signal fault
Code 21 and Code 28 Main oxygen sensor fault (for ES300; SC300 & GS300 models)
Code 22 Coolant temperature circuit fault
Code 24 Intake temperature sensor circuit fault
Code 25 and Code 26 Air fuel ratio fault (for ES300 & SC300 models)
Code 27 Sub-oxygen sensor circuit fault (for ES300 CA & GS300 models)
Code 31 Low airflow meter voltage (for ES300 and GS300 models)
Code 32 High airflow meter voltage (for ES300 model)
Code 35 Barometric pressure sensor circuit fault (for GS300 & SC300 models)
Code 41 and Code 47 Throttle position sensor circuit fault

Efi fuse keeps blowing. After I insert a new fuse the engine starts and I'm able to drive until it blows again seconds later


there is a short in a unit or wire that the EFI unit runs. It may even be in the EFI unit itself. Insert a new fuse and run the fault codes to determine if a fault has been recorded.

I have a problem with a fuse to EFI toyota corolla 2003


Hi there:
Sounds like to have a fuel pump that is shorted out or has too much resistance, this can cause to much of a current draw and blow the fuse. The EFI fuse supplies voltage to the EFI relay and then the fuel pump.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Engine wont start,efi 15amp fuse keeps blowing


EFI (electronic fuel injection) is a nasty fuse to blow. Unplug EFI module for 5 minutes. Plug it back in and try to start it immediately to confirm a heating short or possible bad module.

We have a 1987 stanz, new battery, aleranter and replace one relay switch and both fuel filters. It will start and run(not good) you can drive it a little while and it will run good a minute then blog down...


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

Efi fuse


This is caused by a damaged wire on the engine going to the different parts that are controlled by the EFI computer, look for places the harness may have rubbed through the wire insulation, it will be hard to find, but it will be there somewhere.
