Hey all,

Seems my last post died off a little. Anyways I resolved mnay of the little problems with my new Viper 791XV in my 1996 Trans Am, but now I'm having curious problems with the remote start. Basically when you actiavte the remote start, the vehicle powers up, the starter moves into position, but it doesn't crank. When you put the key in the ignition, it starts, but then shuts down right away....when you put the key in and turn it to run, it starts, stays running, but then keeps trying to crank.

I have connected the Pink Ig1 wire, the Purple wire to the starter wire, the tach wire to the pcm, the orange to Accessory, the factory disarm H2 gr/blk to the VATS relay, and so on. The only wires I didn't connect were the green onboard starter kill wire (I'm kinda sceptical on cutting the starter wire and relying on the alarm to always make that connection) and the pink/white ignition 2 wire (this wasn't connected before with my OMega remote start module). When I run the car, and try the tach learn sequence, that doesn't work either.

Any recommendations or suggestions?!!?

Thanks 791XV in 96 TA remote start issue -- posted image.

PS. Also wondering where to hook the ground wire on my second radar sensor to?? (So it would be grounded when armed)

You need to attach the ground out when running wire tot he VATS bypass ( ORANGE P12 harness ). The car will not start unless your tach wire is properly learned to the system. For the radar sensor trigger, you can use the ORANGE / BLACK wire for the ground when armed.

-ill second that antitheft system, VATS, for ur problem.
-the green wire- i think if you hook it up correctly, then theres no concern that it wont work properly.

take the green to the key side and purple to starter side... thats how starter kill relays have been for years.  remember, alarms are not ment to keep your CDs and radios from being stolen.  they are ment to keep the vehicle from being stolen.  thats what the starter kill does.  also, you are throwing away another feature, the green and purple wires act as your anti-starter grind circuit.  when the car is remote started, only the purple wire has voltage, so if you crank the key,  you wont hurt the car because the green wire wont let the signal pass.

as for the crank problems, go back over the vats relay and resistors.  make sure you are using the right resistor values.  as far as over cranking, when the brain is set for voltage sense, itll only crank its programed amount of time.  i think default is .6 seconds.

I've got it set on tach sense, but I can't get it to get learn the tach. I wil hook up the purple wire and try that, to see if it resolves the anti-grind problem. As for the VATS, I was told to use the gr/blk factory disarm wire....is this wrong?? Which wire is the P12 orange wire?

And which harness is the ORANGE / blk wire for the ground when armed for the sensor??

thanks guys/gals

There is only one ORANGE / BLACK wire on the module. It's the P7 harness right next to the P12 harness. As for the ground when running, I made an error and you should be using the BLUE/WHITE wire from H3/1 or the wire that you stated for the OEM alarm disarm.

That's where I have it hooked up, to the H3/1 factory disarm wire, which sends a negative pulse when the remote start is activated. I'll give the rest a try and see what happens. Thanks Jeff.

You need to use the status output wire instead of the factory disarm wire. The factory disarm only provides a negative pulse at the moment the remote start is activated, whereas the status output stays grounded the entire time it's running.
