05 magnum, 791xv

First time with an 05 magnum.  Doign 791xv, had everything wired in but it will not stay running.  We used a 555c and it seemed to program no problem.  We had tach ,remote and security all learned.  Start the car, it cranks runs for about a second and then shuts down.  I have try 3 different resistances for both starter and acc.  I have also tried a 556u.  All with the same end result.  I a curious what it sounds like to you guys/gals.  Is it a security issue? or a resistace issue? Thanks in advanceandrew nickle

sounds like a tach problem.....if u look in the install guide there is a shut down diagnostics.....it will tell u (from blinks of the LED) why the remote start shut down.......Where theres is a wire there's a way.

Hey Andrew.... 555C doesen't work on there... don't worry though. It's down here right now. We're fixing the door locks, and programming a 556c :-) I'll call you. Gus Wherever I go, that is where I end up......
