    if tach is programming then you have a bypass issue...make sure you have the correct passlock wires.....make sure the bypass learned the correct resistance....make sure the bypass relay is clicking during remote start

    Re: Installing Viper 791vx In 99 blazer?

    and i assume blue status input to the alarm status output if not then there is your problem...check what i stated above....one of those should be your problem

    Re: Installing Viper 791vx In 99 blazer?

    I have the blue/black status from yhe bypass to the blue 4 pin plug by the ribbon harness. So I'm sure its correct. Also now that the led is lighting when I do the tach learn does that mean that's correct?
    And as far as the bypass does it sound like I have the ignition wires right seems like they only can be hooked up one way so I'm sure they are right. Does it matter if they are on ignition 2?

    The led lighting means tach is correct. The bypass is wired correctly however make sure it is. Being programmed accordig to the directions and make sure you have the correct yellow passlock wire there have been instances where there are multiple similar guage yellow wires both of which prevent the car from turning over when cut.

    To see if it is truely a bypass problem and nothing else...simply put the key in the key cylinder when you attemt to remote start it. If it starts, you know for a fact that the bypass module/install is your problem. If it still doesn't start...you need to go back and double check all your wiring and connections.

    Re: Installing Viper 791vx In 99 blazer?

    Ok their is only one solid yellow wire off the bypass which is going to key side of ignition. Is that what you are talking about? Also wanted to say thanks for being patient with me.

    Re: Installing Viper 791vx In 99 blazer?

    Did the key thing and still won't start. So I will go threw and check wiring. Also you guys are sure that the blue wire off the 4 pin plug next to the ribon harness is the right one for statuse?

    Re: Installing Viper 791vx In 99 blazer?

    Why don't you do this. Make a list off all the wires you used (color/harness) and tell us where you connected each one. I'm sure we can help find the problem. Because if it still won't start even with a key in the cylindar...it's def. something in the wiring (it could still be the bypass mod not hooked up too...but something in the alarm install is definately not right).

    I hope you used a relay to drive the domelight supervision and didn't just tap this wire into the car's wiring directly.

    This wire shouldn't be grounded...it can be used off of a switch to activate RS by a switch by pulsing 2 times. I usually don't hook this up to anything.

    You didn't cut this wire did you? It should still be connected to the brain and the relay pack. This wire should just be tapped into.

    When you cut the starter wire...do you have the purple wire going toward the starter and the green wire going towards the key cylindar?

    You could have them mixed up...but that wouldn't stop it from remote starting. Did you test the wire you have to make sure it shows +12 volts when the brake is applied?

    If you could, tell us what color wires you tapped into each on the car's wiring. We know what the DEI wires do...but just saying you tapped into the ignition wire just doesn't give us enough info. So for example say:

    Pink/white to car's Ignition2 White wire.

    Also, I see no mention of you tapping into a 3rd ignition...this is probably the culprit. If you don't energize the 3rd ignition...the car will not start. You will need a relay to make a connection for the 3rd ignition. You can tap into the pink wire of the remote start ribbon harness (just like you used the blue wire from this harness to run to the bypass module) and run that into terminal 85 of the relay. Run a fused wire from +12 volts (battery) to terminals 87 and 86. Run a wire from terminal 30 to the car's 3rd ignition (should ba a Brown wire).

    Hope this helped.

    I was told I did not have to use one from the locall shop so I didint.

    This wire shouldn't be grounded...it can be used off of a switch to activate RS by a switch by pulsing 2 times. I usually don't hook this up to anything.
    Ok so could this cause it? I am also just going to undo it.

    You didn't cut this wire did you? It should still be connected to the brain and the relay pack. This wire should just be tapped into.
    No I didint cut it I used the blue off the mini 4 pin plug.

    When you cut the starter wire...do you have the purple wire going toward the starter and the green wire going towards the key cylindar?
    I have those correct.

    You could have them mixed up...but that wouldn't stop it from remote starting. Did you test the wire you have to make sure it shows +12 volts when the brake is applied?.
    Yes I tested it and got 12+ when pressed.

    I will give better detail today just getting up. And as far as the 3rd ignition the color codes for wiring I got from the bulldogsecurity sit and it was saying 3rd ignition n/a so I did not hook it up. Also I just wanted to make sure we are on the same page. The car will turn over and it will run for maybe a seconde but it imiditly dies.
    .
    Thanks for helping.

    Re: Installing Viper 791vx In 99 blazer?

    I would never use bulldog security codes. I've looked at them in the past and I'd say at least half the cars I looked at were wrong. Either go to www.the12volt.com to look for a wiring diagram...or the best solution is to post in this forum asking someone who is a DEI dealer to email you a tech tip from DEI (they have always been the most reliable).

    I would definately use a relay for the domelight supervision. The output on the Viper791 for domelight sup. isn't really strong enough to power a dome light circuit and eventually you could burn out the alarm brain. Better safe than sorry (especially since you'll likely have no warranty since you installed it yourself). Look at the wiring instructions in your install manual...it even says to use one (I'd trust the maker of the alarm over a shop in this situation).

    I'm almost certain your problem is the 3rd ignition. But just to make sure...when you get a chance, give use the DEI color code and the corresponding vehicle color code that you connected each wire to, just so we can make sure your not going to blow something up .

    Re: Installing Viper 791vx In 99 blazer?

    Where there any extra wires in the vehcles ignition harness? And most def use a relay for dome supervision as the output is only 200ma on a circuit usually requiring in excess of 7a
