Had it running while sitting in the garage. It died and wouldn't start and engine light was on. Keep throwing the fuel pump relay code. Changed the relay and fuel pump Now it won't crank. Acts like the kill switch is turned off and no codes are display. I'm getting power to the fuel pump relay and fan relay but not to the start relay. Checked all the fuses and changed all of them to new ones. Traced all the wires no split wires and checked all the connections I'm thinking the ECU may be bad but I'm not sure. Any ideas?
