Hi, Silverado was jumped off with a jump box due to dead battery. I drove it and it seemed to not want to take the fuel. Then it would not shut off with the key turned off and removed. pulled a relay to shut it off, now it will crank but has a drain on the battery and still want shut off. When it is off and key removed it has a check engine light on. When it’s running there is no check engine light. I have replaced ignition module, checked relays and fuses . Any suggestions and THANK YOU FOR ALL HELP
