So I changed out my pcm with another, tried resetting it. Failed! Swapped ignition switch that matches the pcm swap. Still nothing. Now my battery dies within minutes of attempting to try anything. Any help will be great. I must add if I put my original parts back on it cranks!

I figured out the problem was in the battery current sensor.

No crank no start

Ok so this gets confusing. First off car was bought and ignition switch and colum were apart I dropped the actual switch out from the clip and was starting it that way for a while but had issues with what I think was the security shut off. Sometimes it just wouldn't start crank no start but if I have it a few it would generally start up again. Because it was being started that way I removed some relays when I parked in public so it didn't get stolen. Relays got lost and I tryed to use a jump wire that I think I got in the wrong spot at first. It then would no crank no start. I found the right way and it will crank but not stay running. What do I do
