viper 5701, car wont start

Hi all, I installed a 5701 Viper car alarm in my Yukon XL 1500, 2001. All is working ok and I also got the bitwriter to program the alarm. I will not use the remote start feature, just car alarm and door access. I connected the  (+) IGNITION 1 INPUT/OUTPUT to the ignition pink wire, the RED (+) FUSED (30A) IGNITION 1 INPUT to the pink going to the engine. The starter cranks but the car wont start. Please help !! like I said the remote start will not be used. Thanks.

If I understand correctly all we want is for the ignition kill to work. I am guessing +Pink Ignition wire of alarm to +Pink Ign wire of vehicle.. Yellow Starter wire of vehicle-motor side to violet wire of alarm, and Yellow key side to green wire of alarm. This is how I would try it. I think you made a wrong connection and the starter side is not getting energized. Hope this helps..let me know.

Thanks for the reply, the starter cranks, the ignition does not start the car,

Should there be continuity between the ignition wires with the alarm power off ? thats rhe pink and red wire.

I tell ya .....I have a degree in electronicks and do electrical construction work for about 25 years ......car alarms have changed !!!! bitwriters etc got allot more complecated :)

I think you need to be using the Violet (H3/4) and the Green (H3/5) wires on your starter wire for this. Yellow may be the color, but of course test and verify.  From what I am reading you have a fused wire to your ignition that is suppose to be for 12volt(+) input to the brain.  The download section of this site has a install manual for this unit in PDF format.

which wire did you cut and wire in as the kill switch( viper wires green and purple?)should be yellow wire that only shows 12volts during crank, if you cut ny other wire and tied into these wires theres a mistake. also check all your fuses you may have accidently blown an ign fuse

Thanks for the reply fellas, Vehicles yeloow starter wire is cut and connected to the (violet and green on Viper)

The vehicles pink ignition wire is cut and connected to the (Red and Pink on Viper)

The starter cranks, but theres no ignition.

connect the red wire on the viper to constant 12V+, i don't have a tech sheet in front of me but if i remember correclty it should be red or RED / white.  connect the pink ignition from the viper (and only that wire) to the vehicle's pink ignition wire.

@ joch1314, i love that sig.

I uploaded the wiring, can you tell methe ignition wires ? and whitch one from the 2 that connects to the one comming from the engine. Thanks again.

H3/1 goes to Yukon Pink ( IGN1 ) at ignition switch harness

H3/2 goes to Yukon Red ( +12v Constant ) at ignition switch harness

H3/3 goes to Yukon Orange ( ACC1 ) at ignition switch harness

H3/4 goes to Yukon cut Yellow ( Starter ) engine side

H3/5 goes to Yukon cut Yellow ( Starter ) key switch side

H3/6 goes to Yukon Red ( +12v constant ) at ignition switch harness

H3/7 goes to Yukon White ( IGN2 ) at ignition switch harness

H3/8 not used

H3/9 goes to Yukon Red ( +12v constant ) at ignition switch harness

All wires should be verified with a Digital Multi Meter.  Also verify the Viper Menu 3 Menu Item 8 is still at the factory default of Option 1 ( IGN1 ).

kreg Thanks for the reply, is it necessery to connect everything? I will not be using remote start, I only want the alarm to kill the car if the alarm is on or if the alarm goes into alarm mode.

Never installed one that way.  You paid good money for the 5701, might as well use it completely.  Just need a Passlock 2 bypass and you're all set...

I guess you could just do H3/4, H3/5 and H3/9 ( just to be safe ).

Kreg I ordered the module, from sonic it shuld be here in a few days .........I took your advice :) Thanks.

YUKON 2001

Might as well, you have a nice system and its only a few more wires to connect.  If you ordered the PLJX bypass, set the jumper to "B" and follow the guide for Passlock 2 on pages 6 & 7.   Remember not to connect the Brown "Ground When Running" to the Viper (-) 200mA Status Output ( Blue ) wire until the module has been programmed.

Kreg thanks again I am hooking this up to my Yukon and one to my mothers Buick Randevuz . The module is a DLPKGM. Any advice will be appreciated.

-------------
YUKON 2001

The DLPKGM is pretty straight forward.  Just follow the programming steps closely.

Good Luck!

The Buick is a bit different.  It has PassKey 3 immobilizer.  The DLPKGM does that and some other things like door locks and supplies a Tach signal ( 2003+ ).  Just download the vehicle specific install guide for the Buick and follow that.

do not cut vehicles pink wire! only wire that should be cut is yellow(or purple) for starter kill, the reason truck will crank but not start is you cut the primary ign wire which turns on fuel pump and fuel injectors, put that wire back togehter and only tap the vipers pink wire into it, the red wire goes to either the red or RED / white constant hot

So if I understand it correctly wires 2, 6, and 9 connect to the same +12v constant at ignition switch harnes. Yes ?

-------------
YUKON 2001

Yes, as long as it is capable of suppling the current load required.  Some cars have multiple +12 volt constant wires at the ignition switch ( like older Fords, all the same color ).  On other cars, it is best to go to the battery or the fuse box.

Kreg I think the ukon has 2 ignition wires, one red and on thicker RED / white stripe, split the wires to both?

-------------
YUKON 2001

Yes, I think.   I believe you are referring to the +12v constant wires located at the Yukons' ignition switch.  There are actually 4 wires from the Viper that need +12 v constant. The 3 on the H3 harness you mentioned and H1/2.  If both the Red and RED / White at the ignition switch harness test as +12v constant, split the 4 Viper power wires between them.

A little terminology clarification might be helpful.  Refer to the 5701 Install Guide.  It is available in the Downloads section of this site.  Starting on page 13, it describes the wires found at the ignition switch, their usual name and how to test & identify them with a DMM.

Thanks again Kreg .............this has to be the Guines record on time to install a car alarm :) 3weeks and counting. Next is my moms 2002 Buick Randevuz if you have info it would be greatly appreciated.Thanks again.

A quality install takes time and think of all the valuable knowledge you have gained.   

The wiring guides for the Buick can be found Bulldog Security :  https://www.bulldogsecurity.com/bdnew/vehiclewiringdiagrams.asp  and at the AudioVox site :  https://techservices.audiovox.com/Login.aspx  Sign-up is free.   The Buick is similar and the bypass will take care of some wiring for you, making for an easier install.  If you need assistance on it just start a new Topic thread.
