So I had previously added some extra interior lighting to my 2020 GT Premium with Performance Pack. I removed the lighting today which was installed with the Fuse piggyback type device. I’m horrible with electrical and not good at working on cars. When I put the fuses back in I’m getting no fuel. Error is engine control system detecting fault with the number X injector circuit. I have the same fault in injectors 1 - 8. Have I fried something major? Is it the fuel relay? Any advice?
