Prior to truck shutting off for lost oil pressure it ran nearly flawlessly, now won't start at all; has to be something simple I've overlooked.
Replaced fuel lines, checked and charged batteries, checked alternator, no fuel leaks, system primes to 70 psi during cranking, fuses checked good. Shorted wrench to back of alternator for a few seconds when reconnecting fuel lines; otherwise everything else checks out. Cycled the key about 2 dozen times.
During cranking the battery light stays on and truck feels like it almost wants to start (slight change in tone and sound).
Stuck and need help due to other truck nearing end of service life.
