DEI Hornet 563T not starting

Hello everyone: I have installed a DEI/Hornet 563T back in Feb. The alarm/starter setup worked great with no issues until last week. The alarm now works 100%, but when you go to remote start it, the lights flash , then nothing. I have checked all the soldeRED / taped connections, unplugged the brain, unplugged the battery and reset.  The main mdule has rest at ground for the neutral safety switch, the shutdown is off, etc.

I also found that the brain is not sending any negative signals to the remote relay satellite that starts the car. Directed will not waranty this, and of course I cannot get support from them as I am not a DEI Dealer.

Has anybody come across this issue before? Any input would be highly appreciated.

Thanks

Hello all: Thanks again for all the suggestions: I checked yesterday and here is what I found: First off, the hoodpin is clean as can be, good connection to gnd.  I also removed the hoodpin wire (grey) for testing purposes. No changes. I also tried the shutoff switch back and forth: even disconnected it, no change. The shutdown diagnostics show six flashes, which according to the manual, means the last shutdown was by brake pedal.  I verified that the brake pedal + (purple) was not causing the remote start not to operate (ie not sitting at + at rest).

Interesting enough now, since I have dont the shutdown diagnostics, when the remote start button is pushed, the lights will now flash for 20 seconds, but still no start; before, they only flashed 4 times.

I am really wondering if the main control module is the culprit. I have done plenty of these in the past, but never seen this before; nor have I seen any modules go bad, although I understand it is something that may happen.

Any ideas? Thanks to all who answer.
