I got a viper 4105v and read the directions, hooked all the wires up except the door locks I ran those to a fuse in the driver fuse box but that didn?t work. I try to start it and it cranks and turns over but dies instantly after. The code it?s giving me is ?No or Low RPM or low voltage?. My Tach wire voltage never fluctuates with the gas pedal for some reason it actually stabilizes it. I?ve been monkeying with it for about 10 hours now and I have had no luck. And now for some reason it won?t let me ?learn the tach signal?... did I mess something up? I heard a bypass module will fix this and the door locks is that correct? Or is there a DIY fix for this issue? Thanks!
