I had an interesting day...

My son was driving back from Boston this morning in the '02 100 and about 2 miles from the house noticed a "hot plastic" smell. Pulled into the driveway and smoke was billowing out from under the hood. After the 911 call and the fire department only being 1/2 a mile away it was quickly out. No one hurt, but darn it only has 266K on it... Tomorrow to assess the damages...

I can see people aren't spending their money to fix this. Find the problem harness and replace it. Likely someone has worked on it and didn't take care to put things back together correctly. Any recent starter issues?

 

[rain76king]

So how bad was the damage?

Glad it wasn't worse and that everyone is safe!

Update

I do all the work on it and it goes up on the rack 2x a year for an inspection. It was just on the rack in June with nothing noticable other than the typical ongoing rust.

The truck is at the dealer now and I should here somthing in a couple days.

My initial theory from a quick crawl under, is one of the O2 sensors worked loose and allowed hot exahust gas to blow on to the insulation against the body and a wiring harness that runs back along the transmission / frame on the left side. This melted the wire insulation to the point where it allowed electrical contact. I did not see and fuel involvement so I am hoping it will be minor.

Update

Here is the final result: No major damage. The nuts rusted off the O2 sensor which blew out and proceded to blow hot exahust on to the insulation and wiring during the trip up from Boston. Due to the length of the trip it had enough time to get the insulation burning and just melted the wrap on the wiring. The tech at Grappone said he has seen the nuts rust off before, but never catch stuff on fire.

So, the lesson learned is to check your nuts when crawling around under your vehicle. My wife volunteered to do this next time...

glad to hear it wasn't too bad.

That's good it wasn't anything major. I remember the o2 sensor falling out on my Tacoma because the nuts rusted. If I recall correctly it threw a code which is the reason I discovered it.

Thats what I would have expected, but no code and it was running perfect....
