Viper 791XV, 96 Z28 Camaro

Hi Everyone,  I installed a Viper 791XV on my 96 Z28 Camaro and every feature on the alarm side works perfectly, my dilemma with the remote start.  When I try to start my car with the key it doesn't turn over, however the starter "clicks" like you are trying to start it with a low battery.  It does the same thing when I try to remote start it, the remote start does go thru normal start sequence though.  If I go in and change the anti-grind feature to off in the features menu the remote start works perfectly, but it still won't start with the key.  I've checked all the connections and wires over and again and they are solid.  My V.A.T.S bypass I built with the proper resistor works correctly and did the tach learning and that is fine.  It seems to me it has something to do with the anti-grind/starter kill connection.

Here are how my wires from the remote start satellite are connected:

Green-yellow starter wire on the key side

Purple-yellow starter wire on the starter side

(2) 12V constant- red wire in the ignition harness; both connect to the same wire since there is only one

Orange-brown accessory in the ignition harness

Pink-Pink ignition wire

Pink/White-orange 2nd ignition wire

I’m stumped! Any input appreciated, thanks in advance for your help.

The the only thing I can think of is try reversing the purple and green wires.  It is rare but I have run into 1 or 2 relay packs that the wires were reversed on.

see how you have the 2nd ignition wire from the remote start brain connected to orange, change this to accessory wire from the brain and scrap the brown wire it is not needed, it might work

but the orange is neccesary for remote start in this vehicle, just a suggestion

how do u know pats is right if it does not start and how long has alarm been installed or did the starting problem occur directly after alarm was put in also how did u wire the pats relay bypass

---

thats true, but I would start by properly wiring up the wires in the ignition harness first

Iknow the vats is right because it will remote start without the key in the ignition.  This however, this is with the anit-grind freature truned off.  If I turn the anti-grind on it will not remote start.  Alarm has just been installed so the problem occured immediately.  I cut the PURPLE / white wire going to the vats decoder and connected the key end to terminal 87a and the decoder module end to 30.  I connected a resistor with the proper value to terminal 87 tying into the WHITE/ black wire. 12v constant to terminal 86 and the pink wire coming the four pin harness coming off the relay satellite.

so should I leave the pink/white 2nd ignition wire coming from the remote start satellite disconnected or should I connected it to another wire, if so which one?

n't connect it to anything, accessory wire from brain goes to orange in vehicle, and brown is not needed

---

05gt thanks!  I'll try it today when I get off of work and let you know.

did you disconnect the wires to the yellow starter wire and meter them to VERIFY that you do indeed have the violet going to the starter side etc?  it sounds like you may simply have the GREEN/ violet reversed.....

---

Thanks Kevin!  That was my first thought also......I did in fact verify the violet is going to the starter side and the green is going to the key side.......

The relay that you used for the vats bypass how is that wired?.  ONe more thing you can try, with the anti-grind programmed back on, disconnect the ribbon harness that conects the relay pack to the brain. DO you hear a click when you plug it back in?  You you do then somewhere either the orange or ORANGE / black wires in that ribbon harness are grounding out.

Here's how wired the vats bypass: I cut the PURPLE / white wire going to the vats decoder and connected the key end to terminal 87a and the decoder module end to 30.  I connected a resistor with the proper value to terminal 87 tying into the WHITE/ black wire. 12v constant to terminal 86 and the pink wire coming the four pin harness coming off the relay satellite to terminal 85. 

I'll try to unplug the ribbon harness and see what happens.

You can also try instead of using the pink wire from the relay pack to power the vats bypass use the blue wire.  That might help.

Hey guys..........I tried all of your suggestons and solved half the problem, the car now remote starts with the anti-grind feature on.  Here's what I did:

I rewired the wires from the satellite with orange to orange and pink/white to brown and cut the starter wire in two again, it solved one problem the car now remote starts with the anti-grind feature on (which it wouldn't before), but it still doesn't start with the key.  I tested the wires with a volt meter.....when I remote start the purple wire is getting power and the green isn't and vise versa when I use the key.  This leads me to conclude it is the starter kill, since the starter circuit isn't completing.  Maybe there's a wire on the brain itself I should be looking for, any suggestions????????? 

fyi....I am using the pink wire of the secondary 4 wire harness on the remote start relay for my vats bypass relay!!!!!!

I tried that and it didn't make any difference.........

05gt.......I tried it with both the brown wire connected and disconnected and it didn't work either way.

Thanks guys for all of your time and suggestions!!!!  After more hours on my back under the dash of my car than I care to admit I finally isolated the reason the car wouldn't start with the key.  Cntrylvr79 was in the ballpark on this one.  The orange wire from the 12 pin harness was grounding out under the dash even thought nothing was attached to it and causing the remote start to stay engaged.  Just for sh*ts and grins I taped off the end of the wire and boom it cranked right up with the key.  So the alarm and remote start are working perfectly now.  Again thanks for your all your help!
