Will not crank

i was driving and it stalled out. when i tried to restart all gauges came on but fuel gauge read empty, but had three quarters of a tank of gas. Also, shift indicator had no line under p when i shifted the vehicle into neutral still no indication of shifter location and no crank on engine. tried to tow it home. disconnected negative to restore defaults. no joy. plugged in odb2 maxi scan to see if codes but got link error. pulled fuses and tested with circuit tester and it lit up on all but one. at the time there was no warning lights the odd back fire and was using more gas than usual. i did put in gas system cleaner the day before but acceleration was great.
