1997 yukon won't start

The truck ran fine. Did not drive it for about a month, then it would not fire. The truck has all new igition. Battery, ignition control module, spark pugs, wires, cap, rotor, and coil. It has 63 lbs of fuel pressure at the rail. Fuel filter is also newer. It will almost start, then it kind of sounds like it is dieseling for about 2 seconds and quits. All I get for engine codes are misfire detected. Maybe engine computer or crankshaft sensor?

I'd shoot for crank sensor first.
