2006 Dodge Ram Cummins Remote start prob

Hey all

I have recently put a Compustar Pro 1WSH-S (remote starter) into a 06 Dodge Turbo Deisel. Now the problem with the set-up is once the Truck has sat over night it will not stay running on the remote start. When my customer remote starts the truck, it waits the 12 secs (I have it set to wait about 12 secs for the glow plugs as per customer request), it cranks and runs for approx 5 secs then shuts down. The remote starter then cycles through the start and stop phase 2 more times then gives up. Now i have talked to my distributors about this and we have come up with it either being a poor tach signal, or the voltage in the truck is dipping below the compustar threshold which shuts the unit down. (This truck is equipped with "pre-heaters" in the climate control system, which heats the air in to the cabin befor the engine warms up, they draw ALOT of power) I am alittle unsure about the voltage dropping, my reason for this is that i would think once the voltage drops and the compustar shuts down wouldn't not attempt to start again? Also for the tach i went to the ECM on the drivers side of the engine, plug closest to the rad(i can't think of the wire colour). I have tested the tach multiple times and have not noticed any serious drop. If anyone has come across the same issue or has another suggestion please let me know.

Thank you

Will the truck remote start when it been already warmed up....?

The 04 is a much different breed than the 06.

DOES IT?

This truck that you are doing is one of the hardest I had done thus far. I got the tach wire from the ECM, and I believe that the wire was blue, but I am not sure. I also remember there being about 3 ignitions, one which needed to be powered up by a negative pulse(using a relay). I believe that wire was purple and yellow. I dont think you have a tach signal problem though, because the vehicle is starting. Are getting some sort of inhibit? Which alarm is installed? Since it has been months that I have done a dodge RM, do they have some sort of transponder, or a chip in the key? What is happening to you sounds alot like when you try and RM a GM with passlock un bypassed.
