I was going to post this in the other thread titled ecm fryed but i didnt incase anyone eles has problems. On a lly if u can not get any gauges on the insturment panel to work wiggle the blue wire connected to the ecm. When u get the truck to fire up and it lopes very very bad take the back side of your blue connecter apart and play with the wires and pins in there That was are problem. We got everything fixed now its time to drive it correct. Take it for a spin everything is going good then bam ideals like shit and starts to lope a little. Cyclender and injector number 4 mis fireing. There again play with the blue connecter. If u have any other questions just ask

Kurt, you need to fix this issue of wiggling wires to correct the problem, what happens when you hit a bump at 70 mph and your truck turns off because of a loose wire wiggling? This can be a potential dangerous situation, so get in there and secure those wires........;)
