viper 5901, 2002 dodge ram 1500

I just installed the Viper 5901 Alarm system over the weekend and I am having some problems.

Vehicle: 2002 Dodge Ram 1500 4x4 Quad Cab (with the black key, so no immobilizer)

-First: The system will arm and disarm, the LED on the antenna will flash and if you open the door or shake the vehicle the 2 way pager will alert you, but the power door locks do not work. If I lock the doors with the power door lock switch on the vehicle the Viper remote will unlock the driver's door only. I can't get it to do anything else, lock/unlock. There is only one wire for both lock and unlock according to the diagram and the tech sheet I got with the alarm says I need resistors which I have used.

-Second: The remote start will only crank the vehicle and will not turn it on. If I have the key in the on position and hit the remote start button the vehicle will start. I checked the voltage at the Fuel injector and when starting with the key I get 12v right away, but when checking the voltage when trying the remote start I get 0.079 Volts. Tried switching the Tach signal to the coil and it does the same exact thing as the fuel injector wire.

There is a 5 pin Remote Start Aux harness that has the key sense wire and the other 4 wires calls for diodes, tried installing that, but still just get cranking and no start.


Any ideas or help would be appreciated, thanks in advance.

Did you power up all the ACC & IGN wires and also did you make sure that the wires that you connected are infact properly identified as IGN & ACC wires ? The problem with Dodge trucks is that if not all the IGN & ACC are powered you will get the no start and also if you connect an IGN to an ACC or vise versa, the truck will not start.

Velocity - I believe all the wires are correct and we double checked, triple checked all the wires.

1st point - Yeah the 5901 has one unlock wire and one lock wire and my truck has one wire that locks/unlocks that's where I was confused and when it called for resistors in the tech sheet I was hoping it would solve my problem. I think you are right about the relay module, so my question is where can I get one and how do I wire that in? Is the 451 Relay Module just a generic relay? That sounds like the problem for the locking

2nd point - I am not sure how to set that up as a double pulse lock/unlock, can you shed some light on that?

3rd point - I agree with you on this also, it will start if the key is in the truck and in the on position with the viper remote (defeats the purpose of the remote start lol) I am thinking I need the by-pass module. Its just weird I've read only the vehicles with the gray key have the immobilizer system, but that doesn't sound the case. I was directed to this site about the immobilizer system which might be the remote starting problem.

If you want to take a look about the immobilizer: https://www.justanswer.com/questions/262bw-2002-dodge-ram-1500-v8-4-7-l

I appreciate the feedback, it is very helpful.

Well I just called a dodge dealership and gave them my VIN number and they said my vehicle did not come with an immobilizer system. I forgot to mention the engine in the vehicle is not the original engine, I think the guy said it is from an '05 (4.7L) I'm not sure if that changes anything, but I talked to two dodge dealerships and they both said the ones with gray keys have the immobilizer and ones with black do not and it is very rare to have a black key with an immobilizer. Having a different engine though, could mean I have it now since its out of an '05 and that could be why the dealership said the truck didn't come with it.
