won’t always crank with remote start

I have a 2000 Buick Century that I just did an install on using a Mars-22 remote start and a crimestopper GM-SL bypass.

Every connection is soldered very well, all functions work as they should other then 90% of the time it fails to activate the starter at all, it goes through all the motions, all the relays activate, just note turning the starter... (first 2 times it didn't crank, then the next couple it did start, not its back to not cranking)

I used the smart start feature for the tach wire, but I don't think that's it, it did start a few times in a row fine (oddly in the middle of testing)

Any ideas the most likely source of the problem?
Thanks

Well I messed with it more... it will crank over if I have the key in the ignition in the "off" position. So I figured it must not be holding the programming in the bypass. I looked at that module more, there is a blue wire labeled "-input (ground-in)" so I grounded that to a bolt after hitting the start button and it worked. So from there I grounded that wire and put everything back together. Of course now it still won't crank on without the key in. (now the LED in the bypass is always lit solid)

I am pretty sure it's something to do with the GM-SL bypass, anyone good with them?

Thanks

The orange is labeled anti-grind - out. I will try that one tomorrow, I could tell by the instruction that blue wire went to a - from the mars box, just had not clue which one, there were a few - wires left unused. Thanks a lot!
