93' F150 starting intermittent starting problem. Fuel pump primes, warning lights come on, & click heard from under left side of hood & again upon rlse of key. Otherwise nada. Starter does not try to crank at all. When vehicle does start - it starts right away/no cranking and runs very smoothly. Running gearshift thru gears used to catch & enable starting, but no longer. Have adjusted gearshift indicator wire at steering wheel, but does not seem to matter. Shaking or jouncing truck and/or putting in reverse then park, seems to induce lack of start. Also, checking wires for loose connections sometimes induces a start, but cannot detect any particular wire. Initially it seemed moving one wire got it starting & restarted for a long time, but was at night & can't seem to locate a wire recalling to be that one. New Park/Neutral switch installed when new transmission replaced. Replaced battery & ignition switch (accumulator?) - wire harness plugs into this plastic box bolted to steering wheel column. Thx Mary
