Try the F1.12 in the fuse box near the battery. It's a 30 amp.

Where is 2003 chevrolet tahoe ecu fuse


The ECU will not have anything to do with those issues. ECU or ECM is for "engine control module/unit". Sounds like you have a bad wire.

Hook the battery up or try to jump-start backwards did we?
The ECU fuse gets it's power from the 140 Amp (or 180 Amp, depending on which engine your vehicle is equipped with) ALTERNATOR fuse in the engine compartment fuse block.

99 vw jettal 2.0 gas fuse 29 15amp fuse keeps blowing-no spark unpluged coil and fuse keeps blowing. help please


Thats the fuse for the ECU, engine control module, and is a 15amp for gas 2.0. i would locate the ECU which is under the center of the plenum in the engine compartment and disconnect the long plug. Check for green discoloration on the multipin connector. Sometimes moisture will get in there and short some of the pins together. Leave ECU unplugged and replace the fuse. If it still blows cause is between the fuse and the ECU.

Won't start. gas gauge does not register. no fuel to engine.


CHECK THE "ECU" FUSES AND THE FUEL PUMP FUSES UNDER THE HOOD DRIVER SIDE. DID YOU RAN IT LOW ON FUEL? RUNNING LOW ON FUEL HEATS UP THE AND PUMP BURNS THE FUSE TO THE ECU. "IGNITION ECU" . USE A TESTES OR REMOVE ALL FUSES AND CHECK THEM FOR THAT FUSE CONNECTION THAT GOES FROM PRONG TO PRONG. THAT WILL CAUSE TO MARK YOUR FUEL GAUGE EMPTY AND WONT START THINKING YOU HAVE NO FUEL.

BY THE THE ECU IS THE ENGINES COMPUTER. ENGINE CONTROL UNIT. THAT SHOULD FIX IT. BUT BE VERY SURE THAT YOUR 100% THAT YOU CHECK EVERY FUSE SPECIALLY THE ECU AND FUEL PUMP THE ECU HAS I BELIEVE MORE THAT 2 FUSES. I HAD PEOPLE NOT FINDED THE BAD FUSE AND I GO AND WALLA GOT FIND IT LESS THAN 10 SEC. SEND YOU FEEDBACK PLEASE THANKS AND HOPE THAT HELP U.

I have a 2002 Kia ECU system fuse burning all the time


Assuming the correct fuse is being used, there is a short somewhere in the wiring leading to the ECU or in the ECU itself. If no modification has been done to the wiring (such as aftermarket radio or alarm), the ECU may be bad. A dealership may be able to test the ECU if you remove it, but will probably charge for the service. You may be able to find a cheap ECU at a junkyard for the same cost. You can use an ammeter to check power consumption at the fuse slot. If there is more than rated amperage consumption with the key on, engine off and ECU in, there is a short. Remove the ECU and recheck. If there is more than about a hundred milliamps with the ECU out, the short is in wiring. If not, the short is in the ECU. If there has been modification to the wiring, check it for shorts or exposed wires, and remove the mods if possible. You may also be able to get a pinout for the ECU from Kia and check for incorrect shorts to ground on each pin using a self-powered continuity tester.

Blown ecu fuse


ECU= Electronic Control unit. This is what controls all the engine electronics. All the sensors on the engine and other things are routed through the part. What it does is tells the engine how to run. Each sensor plays a specific role. The ECU reads how much are the engine is getting, tells the engine how much gas it needs, etc. Try digging around a salvage and finding a new ECU. Swap it out, and if it is still blowing the ECU fuse then you need to start looking for shorts.
