I canít remember where the ground is. But I had the eco flashed to get rid of the immobilizer and a tune for the intake and termi exhaust.

I figured out my issue.
I had a ground improperly placed. The ground near the ecu was going to the battery instead of an actual ground. woops.
immobilizer seems good now.
No flashes.

Still need to figure out why the starter isn't getting signal.

Thanks yall!

can you shed some light on my situation?

The LED flashes twice to indicate that the key in the switch, or the immobiliser antenna, or both, are faulty
Does this happen with both of the black transponder keys or just one.

Is there a connector that is likely disconnected? If so where?

If I unplug the smaller connector attached to the key switch then it flashes twice...

sadtaco OK. I'll double check and see if I can locate that serial connection.

Mobilespider Ok, watched your video a couple of times now.

looks to me that you have 1 flash
I see it come on after the dash dance, goes out for a period, flashes once, goes out for a period then stays on.

On mine the flashes are 2 quick ones. I should video mine to see how it looks.
Mine does everything you indicate on yours when I turn the key but mine does not start, nothing happens when the button is pressed. If the Immobilizer is kicking in then you lose starter and ignition but EFI system still primes.
