Should start witout doing crankshaft relearn.....in fact it has to be running to do that procedure. Might have to take truck to good shop to get it figured out. I would have to have it my shop to see whats going on at this point. Guessing is not a good procedure and you may spend more than if you just get a professional diagosis than throwing parts at it.
but throwing parts can be really fun ...especially if they're glass.....never mind.
