About 55,000 miles. 5.9 liter engine.
I have started having problems recently. Sometimes, it would crank,
but would not start. Then, sometimes, if I "reboot" it by
disconnecting battery for a minute, then it starts. Also, recently
I put it in reverse, then in forward again, and the engine stalled.
This morning I could not start it altogether, although I had
relatively little time.
I own a code reader and a repair manual and would like to try to
figure it out myself.
What would be a sensible problem solving approach here?
