Got my AEM 1052 Back from Service, tried plugging it in to make sure it still works, Engine fired up, than died. Didnt start back up. Plugged OEM computer back in, still doesnt fire back up. Engine keeps turning but doesnt start. Unplugged and Replugged battery. Any ideas?

You can start by verifying you have fuel and spark. Give it 10 seconds of cranking then quickly pull a plug, if you get no spark it will be soaking wet. But even before this, have you looked at AEM while cranking? May be crank angle sensor isn't coming to computer so the AEM isn't delivering spark or fuel.

 

When they serviced your EMS did they reset the tune?

My guess is that its flooded. Pull the spark plugs let it sit overnight, and begin again tomorrow.
