i have a 2000 elantra gls standard and it shut off the other day after i cut the silencers off my exhaust. i replaced them with just some straight pipe but to drop the exhaust i unbolted the pipe all the way back behind the flex pipe. my o2 censor was disconected and i guess i didn't plug it back in good and it came loose while i was driving and melted it self to the pipe. i got it back in but my car still won't start. i'm not sure if that's the problem but i'm almost positive. it will turn over but won't start.......almost like it's not giving any fuel or maybe the ecu is messed up.......can anyone help me out.

Sounds like will just need to replace the o2 sensor. <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

If it melted the worse that happened was it short circuited, which I don't think should be a big deal. The amount of voltage the O2 puts off is very little. However if it is a heated unit it would have also had power running to it.

Have you checked your fuses?

If you ECU is shot... replace the O2 sensor and get it towed in for warrenty work.... Better cover your trail of mods though.

On second thought... how about a stand alone system? Haltech E6K is what I have on my Suzuki Sidekick. It's laptop programmable and will run ANY engine.

02 sensors are like 60 bucks... unless your a serious performance freak and are willing to put in the dyno time to properly tune a stand alone there really isn't a reason to go stand alone (500+, last i looked a good haltec unit cost 1k+, just the last time i've seen, they might have come down). not to mention all the other wiring that's required to go with a stand alone.

When the sensor melted, it probably shorted and blew the fuse on the ECU.

Well I was thinking if you have to replace the ECU (your cost)... why not buy a stand alone unit. But I keep forgetting about this wonderful warrenty we have <img src=/images/forums/snitz/cool.gif width=15 height=15 border=0>

My Suzuki Sidekick has a Mazda RX-7 motor in it. Take a look: http://www.daczone.com/suzuki.htm
