SOURCE: 1999 Hyundai elantra died while driving found ecu

Check your o2 sensor harness. The harness if not properly secured will rub on the axle to a point where it rubs through the insulation of the wire & shorts on the axle causing the ECU fuse (20A) to blow. Repair the harness & replace the fuse & bada bing! You should be in business! Hope that works. IF NOT follow this K.I.S.S.

SOURCE: I have a 2000 Hyundai Accent that keeps blowing

The ECM1 fuse blowing usually indicates that the fuel pump wires shorted inside the tank. If you drop the tank and remove the module, you will probably find the insulation burned off the gray pump wire.

99 elantra alt not charging battery' installed new alt and battery and fuse good and still no charge on battery


check 10 amp ECM fuse. Your alternator voltage is regulated by the ECM. If the fuse is good, consider replacing the ECM.

O2 sensor replacement procedure on the avante 99 ( elantra ),. does it need to reset the ECU after replace it??


Yes you do. The ecu will still have that code stored and will think it still has to run like it was before you put the new one in. You could try disconnecting your battery for a half hour sometimes this will remove the codes.Better off just removing them with a scanner though.

I have 99 Hyundai elantra that has a problem starting occasionally, if I let it sit for a while it will eventually start. It turns over but won't fire.


Check your fuse's. ECU inparticular. It will be a 20A fuse. I had a problem where the O2 sensor harness was creating a short & blowing the fuse. Finally figured out it was the harness that had worn down because it was laying on the axle. Repair the harness, new fuse & your in business. whatever you do K.I.S.S. Keep it super simple & it wont fail!
