2000 Honda Passport ECM/PCM issue
 

i had posted this on a honda tech forum, but was recommended to post in an isuzu forum...so here it goes!

i need help pretty bad!!! here is the situation:

i started my vehicle (2000 Honda Passport 4WD EX 3.2L V6) and started to drive when the engine cut off, but left all electrical on...when i tried to restart, it would turn and turn, but not crank...certainly didn't sound like anything mechanical, so the first thought was electrical; therefore, i checked fuses...i noticed the ECM fuse was blown...i knew there had to be a reason the fuse blew, so i replaced it and tried starting the vehicle again...started like a champ as usual, but soon cut off again (same way)...because i was near a parking lot, i decided to try and start it again...it started up and as i was pulling into the parking lot, it cut off again...only this time, the vehicle tried to restart itself being in the accessory position, made a horrible scratching noise, just before smoke starting coming out of the hood and burning wires could be smelled...when i opened the hood and extinguished the small fire that started, i noticed that several of the wires from the ECM harness had burned up and caught the plastic tire cover on fire...

soooooo, anyone know what could've caused this and how easy it would be to replace the ECM? and would replacing the ECM solve the problem in the first place?

thanks for any information provided...it is much appreciated!!!!

If the wires in the ECM harness burned, you could be in for serious and expensive repairs.
Replacing the ECM is simple, only one screw on each of the two ECM plugs and then unsnap from the mount. It will have to be reprogrammed to your VIN#. I found one for my 2001 Rodeo LS on Ebay for $40 with free shipping and it worked great. However, as said previously if the harness burned, no telling what other damage to the wires could have happened. A professional opion is warranted here I believe, so take it to an auto-electrical specialist shop. Hope this info helps.

i have assessed the damage and can tell you that several of the wires have broken off...i have contacted several places online that claim to have what i need, but until i see a picture, i can't just send money out...it doesn't look like it would really be all that hard to replace if i could just get the right part, just a bunch of connections and weaseling around under the hood...i appreciate that info!

I had a same type of issue and found out that the wire harness in the drivers side where it hooks in to the box were frayed. fix em' and all is good now.
