I was at track and went to change chip and went to start car and wouldnt start for ****. Changed chips back to good known working chip and nothing again.. Throws CEL and it stays on when you jump conversion harness cel wire. Code 0(ecu) Wont start, gets fuel and spark but seems to have a problem. Back up fuse and ecu fuse is good and so is main relay....any idea?????? Tried another known ecu also...same results

 

could a wire touching another wire like on o2 sensor cuz it to throw a code 0 solid cel and not start. i didnt think so but also dont know everuything

 

same thing happen to my p72 ecu...mite of fried the ecu...at least mine did

 

A solid cel usually means you have a ecu malfunction such as a bad ecu.
Try another ecu.

 

did you happen to shock the ECU when you were changing chips? ive done it before and fucked up a ECU. so now i have a ground strap attached to my arm going to the door hing when im playin with ECU's

I would guess that when you were playing with the ECU, one of your harness plugs might have come loose.

I would doubt that you 'shocked' the ECU and ruined it though. I have played with HUNDREDS of OBD0/OBD1 ECUs and never once 'shocked' one to death.

Always ends up being a bad chip, a bad burn or wiring issues...ECUs are pretty solid pieces that rarely fail.

 

sounds like you have a short somewhere in your harness. check to see if you have blown any of your ecu fuses

 

Also, try the ECU in another car to eliminate the ECU being bad as well.
