You have a dead short somewhere after the fuse. You will need to locate and fix it to resolve the problem. It will NOT clear itself. If you are not comfortable with searching for the problem yourself, you really need to have a competent automotive electrical tech do this for you. Either take it to a mechanic you trust or have somebody you know who is competent help you out with this. It only requires basic tools and some time.

    If you have a multimeter (preferably an electronic one with a continuity tester that has an audible warning) you can very easily seek the short. i use the term easily rather loosely here, though, because it will take time and disconnection of under hood or under dash components. Hopefully, the short will manifest itself quickly. You will basically test point-to-point, working away from the fuse block until you locate the bad link. Like i said previously, if it isn't something you are comfortable with, it's best to leave this to someone who is. Also, without a wiring schematic you are really searching without a map. Sometimes wires disappear into looms and firewalls or duck behind manifolds and such, so you need the schematics to tell you which components you need to check continuity between. i'm sorry not to be of more help, but sometimes we just have to bite the bullet and take our problems to those best suited to resolve them for us.

    Best of luck,
    matt

CHeck the O2 sensor wiring. If it is shorted to ground it will blow the fuse every time.

Citroen xsara picasso 2.0hdi battery fuse keeps blowing.


If it's the main Fuse, rated above 40Amps, then usually only two components are directly connected to this circuit. The starter motor and the alternator. Both can get critical short to ground, that may blow such fuse.The thick battery cable goes directly to the starter motor and a smaller high amp wire is looped from there to the alternator. Third less likely would be main supply to ignition key switch.

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.

Hello! Identify which fuse is blowing...also, does it blow as soon as it is installed or does it blow when you turn the key? Lastly your not referring to a fusible link but a maxi-fuse...ie...40; Correct?

The car died on me in the middle or the road . The #1 fuse blows


Check your ignition/fuel pump relay---it's with all the other relays in a dash tray---it's ORANGE---check it for dead-short.

Toyota Camry 1994 Main Fuse keeps blowing


-if your fuses are blowing
-the problem is in the wiring
-because if too much amperage flows through the fuse will blow
-there's probably a short to ground somewhere or high resistance after the fuses causing it to draw more amps

The main fuse in my dodge stratus keeps blowing


Try unplugging the transmission range sensor. It is a common problem for them to short out and they are powered when the key is in the start position. Replace the fuse after unplugging the sensor and see if it blows the fuse when you turn it to start. If it does not you have found the problem.
