I bet you $ to donuts you\'ve never seen this Viper problem-
I got in my 1996 GTS, got the key 3/4 of the way turned as I proceeded to start the engine. Before the engine turned over, the speedometer hand did a 360 degree turn-yes, it lapped itself. I let off of the key, then turned the key again to engage the ignition, and it did it again. As I released the key, the speedometer hand relaxed(went to 0). When I jiggled the key, the speedometer hand went to maybe 80 mph. I tried again, except that time the odometer on the trip gauge started advancing at an incredible rate. I started staring at it thinking maybe it was just the trip gauge and that I would be able to reset it, when to my dismay the cumulative odometer began advancing as well. The odometer probably advanced 4 or 5 miles while I was sitting there. I quickly turned the key off and removed it from the ignition, so my low mileage car didn't quickly become a high mileage car. Has anyone seen anything at all similar to this???
A little background: the starter failed and was replaced about 2 wks ago. The Viper shop said that was their first GTS starter replacement in 7 yrs. of doing business, i.e., it's normally a very reliable component. During 3 or 4 previous occasions(in the last 3 months since I became a Viper owner), my speedometer and odometer quit working. They showed no signs of life at all. Then, they would spontaneously begin working again. I did put the car on ramps a month ago and found an unplugged electrical module (3 or 4 pin)on the left side of the transmission. I believe it was a "speed sensor". I plugged it in, and had experienced no further episodes of speedometer/odometer failure until today. The lack of further speedometer failure may have been coincidental to the plugging in of the module.
I also installed a shift light 3-4 wks ago. The speedometer had shown signs of failure before then. Lastly, the electrical system was also tapped when the nitrous system was converted from a dry system to a wet system by a local Viper shop 3 months ago. Any advice would be most appreciated. Is it possible that the odometer is "catching up" with mileage that didn't get recorded when the odometer wasn't working, but mileage that the computer has recorded??? I probably had 100 miles that didn't get recorded. I would hate it if the odometer for no reason went to high mileage-mileage I didn't even get to drive!

Anyway, the problem is likely electrical as Joeseph hinted. Measure your voltages if you can. Just my .000002 cents.
