Problem with ECU Fuse and engine starting!! HELP PLEASE!!

[XdarkTibX]

well.. todai i just got my O2 Sensor rewired (lengthened) and i was crusing around good. but after like 10 minutes, my car just died.. it wouldn't start.. but i found that the ECU fuse was blown. well, i changed it and worked out good for 10 minutes and than blew again. so i got another one (this time, i thought it was the O2 Sensor rewiring that went wrong so i took the #2 Sensor off) and right when i put the fuse in, it blew. Now my car is parked at a Giant parking lot trying to get something fixed. all i know is that the guy who was rewiring, he accidently cut both white wire at the same time so he was not sure which one went with which. is that possible...? did my ECU get fried because once i put the ECU, it blows right away... does the car usually not start if the #2 O2 Sensor is off...? (i had my car with only #2 Sensor for while with CEL.). please help me. imma leave to korea this saturday and my emission is due tomorrow!!! oh gosh... wat do i have to do...?

well you'd think if he'd have crossed the wires then it wouldn't take 10mins! maybe he used the wrong ga wire and it burt the insulation and now it creating a short?? good theory huh?

I had the same thing happen to me when I got my headers on. What happened with mine was that the guy had disconnected the 1st O2 sensor. After I plugged it back in and got a new fuse it was working fine. I'd make sure that the 1st O2 sensor is working and you should be fine. Hells bells, my second O2 sensor isn't plugged in properly but ot seems to be working ok. Good Luck

This is kinda obvious.

The car ran fine...


Car had some wirirng done.


car now blows fuses.

HAS TO BE THE WIRING.

NO the ecu did not FRY thats is EXACTLY what the ECU FUSE , PREVENTS !!

Check the O2 sensor cable for shorts, mine got caught around the driveshaft once, rubbed
the insulation off and popped the ecu fuse.
