06 dodge ram r/s issues

I have installed a DEI 561R with a PKUCH2X in a 2006 dodge ram 1500 and I'm having a couple of problems. First I can't get the r/s to recognize the tach. I measured 3.4 volts AC at the injector and on the tach wire next to the r/s and it still won't program. Second about 50% of the time the truck starts and shuts off after a few seconds the other 50% it starts and stays running. Temperature doesn't seem to matter. If I leave the key in the ignition it starts and stays running every time. I tested the bypass module's programing by holding it next to the ignition cylinder and starting the truck with a disassembled key and it worked fine. I used the PURPLE / brown mux wire right next to the ignition cylinder and I tried a 1k ohm resister between the bk and pink wires of the bypass and nothing made a difference. I had the same problem on another 06 ram that  I used to have and its driving me insane! Thanks for any insight you guys can give me on this.

I tried the coil for the tach as well as the bk/or at the pcm made no difference. When the truck doesn't start the security light flashes but I don't think it comes on solid. I'll check for sure and i'll check the gwr. Weird thing is I had the same problem on a different 06 ram with a different 561r and a different module but it did the exact same thing excluding the tach problem. I also got an engine light and an airbag light on two seperate occaisions but they cleared when I restarted the truck with the key (airbag) and disconected the battery (engine light). This thing is driving me nuts I can eventually get it to start after a couple of tries but it's a pain having to watch and listen every time instead of just hitting the button and forgeting about it.

thanks
