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

It was running - no reason to replace anything ignition-related. 

 

You either need to do a hard reset (disconnect battery for an hour or more, then touch the positive and negative wires together [away from the battery, of course], then reconnect both to the battery), or you need a new battery (voltage too low).

 

If the jump pack somehow put out more than 15v, you could've fried a module or 2 as well.

 

Usually sudden problem like this are due to logic lock (need to get the STUPID out of the computer by doing the aforementioned hard reset), loose / corroded battery cables, or low battery voltage. If the battery was removed at any point my money would be on something related to the cables.
