2006 Ford Ranger • 193,000 miles

My truck was running fine. I connected a diagnotic monitor that I just received. It was marking zero problem code. However, after a while my truck began to shake and then it stalled. Now I am not able to re-start it. The engine will turn but will not start. Did the diagnostic handheld device damagae my truck's computer? I disconnected and reconnected the battery hoping to re-set the truck computer and it still will not start. How can I fix this?

As long as you didn't change any parameters in the computer, the scanner shouldn't have caused this issue. Have you checked to see if the fuel pressure is within spec as well as are you getting spark to the plugs?
