You are going to have to go to the dealer and have the system checked
with a Tech II. Or if you know someone with a snap-on scanner or
something like it. The VTD will have a stored code/freeze frame
records. Without it, there is no way to tell which direction to go in
My 2003 Blazer LS 4x4 4 Door w/ 16,000 miles on it does the same
thing. I have a Viper remote start on it, and it only seems to do it
once in a while (once a month or so).
Sometimes the security light will flash really fast, and then the
engine shuts off (radio, lights, dash lights all still stay on, but no
brakes and steering power). Lots of fun while driving down the
highway at 70.
My Blazer has left me stranded where it wouldn't start a couple times.
Of course those times were when I had a car full of people needing to
get to a concert, or something like that. It just cranks and cranks,
and won't start.
I have had it in a couple times to the dealer to fix it, and it seems
to fix it for a couple of months, and then it starts doing the same
At least I only have a couple years left to my lease. Then someone
else can deal with the problems.
It's the pass key bypass module:
For the remote start. They have to be synchronized with the ECM so that you
don't need the key in the ignition to start the vehicle.
Have the installer of the Viper remote start system, replace the pass key
That's why I gave up on all brands except Audiovox, Prestige (Which is
Aaudiovox), Code Alarm and Auto Page.
