I just purchased this truck. It’s a 2000 srw ext cab. Manuel 7.3 this is all new to me so please Understand that. Bought the truck not running. Replaced icp sensor and truck started and ran fine. Drove it for about 2 weeeks back and forth for work. No issues. Here’s where I messed up. I ordered a ts6 position chip. Pulled the truck in the garage disconnected the batteries keys out. Removed the pcm cleaned it good just like directions said. Although I re-assembled and tried tried to fire it when realizing I hadn’t plugged the pcm back into the truck harness. So realizing this I disconnected batteries again plugged in pcm and re connected. Crank no start. Batteries and keys back out I pulled chip cleaned terminals again re installed batteries ect. Crank no start. So reversed process removed chip putting it back to stock. Still crank no start. Only part I messed up is trying to start the truck with the pcm unplugged .....Is it burnt up or am I looking at another issue? Thanks I’m advance for the help
