What kind of issues? Is the alternator light on? Have you put a voltmeter on the battery with the motor running?

More info please

Yes, everything was good for a couple of weeks. We let it sit for a few days, and boom, it wouldn't start. Jumped it of and the check engine light was on. Let it run for 20 minutes or so and cut it off. When trying to start again, it wouldn't start. Charged the battery with a trickle charger and it started, but wouldn't restart. Had the started tested and took another new battery from another vehicle and did a draw test, nothing drawing any power. Please Help

The voltage was 13.1 and 12.9. I unhooked the negative and with a test light started pulling fuses and relays.
