Thank you for the advice. See the problem is that I had a car come into the shop having problems with the security system, the immobilizer would shut down the fuel pump while driving. So I hooked up the scanner and a lot of codes came up

. One was related to the anti-theft module circuit fault and the rest where related with the body, about 15 codes

. Maybe a faulty BCM. Well I tried to clear codes and now it won't start.
