[quote=”EricTheCarGuy” post=21904]I’m not sure I subscribe to that theory, what tests were done to make this determination? If he really went through any testing you would have a good idea where the ‘short to ground’ was. First check all the fuses as a blow fuse can cause that problem. Also try resetting it by disconnecting the negative battery cable and touching it to the positive cable for a few seconds and then reconnecting it to see if that changes anything. Lastly if the ECU got wet due to a leak or someone spilling stuff on it take it out and let it dry out for a bit and then reinstall it to see if it works then.[/quote]
Hey Eric, been watching your videos for a long time. sorry to dig up this old post but i have recently been having an issue with my 1994 legend . I have come to also believe that it is potentially a short to ground inside of the ecu. Let me back up a bit there, I had replaced the alternator with an oreiley reman. witch i am guessing either caused or made this issue worse . thing was throwing almost 17 v at the battery. Before i was able to return and replace it the car exprienced some sort of surge and then shut off. Come to find it had fried the cooling fan fuse, cooling fan relay, and ecu fuse replaced all and tried to fire it, now it’s just blowing the ecu fuse/fuse 5 every time. If i remove the main relay the fuse will not blow when i turn car to “on”. so i started unplugging connectors to try to locate a short and bingo IAC connector is short to ground. traced the short back through the loom untill i unplugged the ecu. and boom short to ground dissapears from the whole of that yel/blk whire that runs from main relay to fuse box to relay box c and iac and everything. So now i am looking for an Ecu for the Elusive 94 6spd blk sedan! Any help would be greatly apreciated. I firmly believe that if i didn’t own this car it would already be in the junkyard, but i am commited to keeping it on the road.
