2002 Ford F-150, Viper 791XV Alarm/Remote Start

Sounds like you missed an IGN or ACC wire to me. Make sure you double check your wiring.Jeff

Shaughn, I would normally agree with you----- I rarely or never power up the radio-accessory wire on Fords, and I've had very little trouble. On the light-duty Ford trucks, though, if you've noticed...........when you first remote start them, the dash gauges and digital odometer are dead......after about 10 seconds they finally wake up. I've always gotten away with that, and had no troubles. But, look at my post over at carsound.com about that Focus. On all the Foci I've done in the past, I've NEVER powered anything but the one main ignition wire.........and I had no problems, until just that one car. And another guy there said the same thing about a Taurus.....another car in which I've never powered the radio wire. So, this fix has worked for two other Fords; might be a good thing to try for this one.

There may be three accessory wires that need to be powered up and one ignition. There ae versions of these trucks that use two RED / black wires in the ignition harness. One is an ignition and one is accessory. Have the installer recheck that the wires he has tied into are hooked up the correct thing. If an accessory wire is hooked up as an igntion strange problems will occur. The listing I have is Ignition is either RED / Black or Blue/Green. The three possible accessory wires are Reb/Black, Gray / YELLOW and BLACK/ Green. Also make sure that the ground for the remote starter is into the chassis and not a piece of steel in the dash.sparky

well i know the 200mA 2nd accessory output from the alarm is not hooked up. is that the wire that may be causing it?

so when you say that are you talking about my 200mA 2nd accessory wire (orange wire) from my alarm needs to be powered or is it some other wire? i know that my 200mA 2nd accessory wire is not hooked up. would that mean i need to have it hooked up to a relay? im new to the whole car alarm thign and i dont want to screw anything up worse. lol. thanks for all the help.

i checked about my gauges just now and when i remote start my truck they take a little bit to turn on.

No, not the 200ma accessory output........we're talking about the multitude of different ignition and accessory wires coming from the Ford's steering column. Regardless, are you trying to get this figured out because of curiosity, or you're tying to help out your installer, or you plan to fix it yourself? Any good shop would be eager to correct their mistakes........call them, set up a time, get it back there, and have them fix it. Do you want to do a little bit of troubleshooting on your own? If you want to verify my theory, here's how: 1. Disconnect truck battery for a minute or two, then reconnect. 2. Start engine with key, let it run a couple of minutes......verify that the check-engine light is OFF. 3. Activate the remote start. As it is cranking the starter, quickly begin to insert your key in the ignition.........the very moment it finishes cranking and the engine starts, BANG! quickly move the key backwards to the radio position. Leave it just like that......running with the remote start, key in the accessory position.........leave it like that for a few minutes. I'd be willing to bet you get no check-engine light. 4. Kill the remote start by hitting the brake, and remove your key. Activate the remote start like you normally would, and let it run for a few. Is the check-engine light back?
