Hey all. Well i installed a new tapshift kit yesterday, and when i was done it had a no start no crank situation. Ive searched through the forum and only found one post that sounded somewhat similar to my problem. Well here is where im at. When i go to start the truck the key turns over but no cranking, the volt guage is all over the place (kinda jumps around) and my fuel light is on and says my tank is empty (just pumped 28g yesterday). I did notice the dic has all the gears on it but no line under anything to signify what gear its in. Went through the instructions again and rechecked my work by pulling the tcm. checked pins, connection seats, rub, and connectors. When the starter didnt crank i did put a battery charger on it. I also haven't tried disconnecting both batteries to see if that clears anything up. Any help will be great. Thanks in advance for any info.
