Default Terminator X possible LED lighting issue?

Hello all. I am experiencing something strange, and I don't know if it make sense at all. Back in April I added the Hyperspark ignition to my existing Term X. After a few minor hiccups, got it running. At that point I had it tuned by Andrew ( Dr. EFI ), and it's been running awesome ever since ( still have to get back with him to go over stuff). Here's where it gets weird, last week I decided to change my tailight bulbs and marker bulbs to LED replacement bulbs they needed to be replaced anyway. Car was running great, I shut it off and changed the bulbs. Tried starting it and no dice. It will crank, fire, then die unless I pedal it to keep it running. When it briefly starts all lights on the ECU are green ( normal ). After going back and forth, and going over everything I could think of, took the bulbs out, then I tried re-flashing ECU and re-installed map from both the laptop and SD card. Still nothing. Then I remembered an article by Chris from EFISYSTEMSPRO, that mentions to check to see if IAC is working, you should be able to see it move with intial key on. Checked that, and IAC does not move either. Is it possible that the bulbs could effect something? I didn't touch anything else before this happened. Any info, thoughts , ideas would be appreciated. Thx.
