My problem is almost the same, It sometimes does not start in the morning, (no spark) but later in the day it seems to most of the time. Once it starts it seems to keep on starting until the next morning. No codes but changed the crankshaft sensor, camshaft sensor, and swapped the ASD relay. Shaking harness produces no changes when running or or not starting so I do not think I have a back harness issue. Maybe a ground or something with a thermal mechanical aspect to it. Any ideas?
