viper 5704 in a 02 rendezvous

H3 does drop when started. So if I switched to w2w I would have to hook everything up? :( doesn't sound like fun. if I'm gettin 12V out of starter wire, why isn't it starting or at least attempting to? Would this mean its something with the car?? Thanks again.

Great. I drove for about an hour today and when I got home, none of the dball functions are working. Looks like I've still got a lot to do...

Time to double check all your connections.  Everything some be securely soldered and well insulated.  Make sure all the connector plugs are fully seated and latched in place.Soldering is fun!

Well I reprogrammed the db all and its fine again. Wonder what would cause it to "forget"?? Now back to the alarm. If I'm gettin 12v out of the starter wire (to starter) when I hit the remote start button, does this tell me its something on the car side, meaning that its nothing on the alarm side? How can I test to see if I hook up a tach wire if that will fix it?

As a test you could just set the Viper to Engine Checking OFF and select a fixed 1.0 second crank time.

Here are a couple of alternate Tach sources.  Connect the Viper VIOLET/WHITE TACHOMETER INPUT WIRE directly to the

source listed and do the Tach Learn Procedure. 

Bulldog Security :

TACH   PURPLE / WHITE (AC)    @ IGNITION COIL

DEI :

Tachometer    NOT pink  (ac)     @ any fuel injector

Also verify the Vipers D2D jumpers are set in the horizontal position.

Of course, if the Viper is already outputting the Starter H3/4 Violet +12V signal during a remote start attempt and you

tried a remote start with the ignition key in the cylinder ( but not turned )......

Perhaps you could list your Viper H3 to vehicle connections very explicitly, even a photo.  That might help.  Also

detail the vehicle sequence during remote start. ( Dash lights, starter motor, etc.  There is some DB-ALL diagnostics listed on thenext to last page of the install guide that might help, too.)

As for switching from D2D to W2W, it might resolve/prevent the issue you had where it worked for a while, stopped working

and had to be re-programmed to the vehicle.

Soldering is fun!
