Hey guys, recently i used a 2008 wiring harness on my 07 motor / ecu, the car started up fine but we threw a code for intake cam sensors bank 1 and 2. We swapped the 07 harness back but had to repair it and solder some wire back together and o2 harness connectors.

Now the car wont start, code are all gone.
Theres fuel in the car

Any leads of where this could go?

Would it be possible the ECU thought it was being stolen or something?

Thanks in advance.

( reason why we switched harness's because we thought the new harness i got was a 07, apparently it was an 08 due to the upstream o2 connectors being different. ( My original 07 MT HARNESS was damaged but now we had it repaired by soldering everything back together.)
