2006 Chevy Impala no start/crank

Hi guys, I just installed a autostart 1780 with a idatalink alca on a chevy impala 2006, it programmed fine, but when i remote start, the ignition and lights turn on with the radio and heater but it doesnt crank, and it stays like that until i turn it off, did anyone run into this problem? i have installed on chevys before but i never had this issue. I double checked all my wires and everything seems good. thanks

the alca is flashed gm10 and i am using dbi.

is the Black/white on the ALCA hooked up to accessory?

also does lock/unlock work? i have had autostarts with a bad data port. try using the ads port instead of the dbi

also verify with a test light / meter the orange wire on the autostarts drop out when you try and remote start. ( ign and accessory come on, and then accessory drops.. this tells the car the crank the starter)

yeah the black/white is tapped in to accessory on autostart then both go to the brown wire on the car, i will try the ads port i was thinking that also. thanks

unlock and lock works

Flashed the bypass to ads and it worked, but the brake wire wasent working through data, it worked couple times on and off, so i tapped the brake wire from the remote start stright to the bcm.
