ford f150 remote start not working

The vehicle is a 06 ford f150, installed a prestige 977A with a PKALL bypass everything works except the remote start. The bypass is programmed according to instructions, it starts with the key in the ignition test but thats about it, the tach is programmed, did it diagnostic test and got 2 flashes on the park lights which according to the instructions is a low tach signal, i have the tach wire connected at the uncommon wire @ coil. The software on the bypass is 4.06, whatelse should I try ?Protect what's yours.

See if it start when set to tachless Make sure rx and tx aren't reversed Make sure starters not bad unlikely Make sure ground is solid Make sure the bypass is comming on during start sequence

Lol, you know I'm so use to always connecting the tach wire I sometimes forget about those other options. I triple check those rx and tx wires also. The light on the bypass is always on.Protect what's yours.
