B+ to F/P now no start
 

Hello everyone!
Impossible to make the first post without an issue.

The car is a NBFL 2003 Nevada.

I have managed to stick F/P and B+ together and now the car dies without me using F/P with GND.
as soon as i pull the wire out of the diagnostic port it dies.
no errors on the car through obd either.

The fuel relay has been replaced and all fuses checked to no luck.
Anyone did this before ? Anyone fixed it ever ?
