The ECM uses the camshaft sensor to start and shifts to reading the crankshaft when running If I recall correctly. Thats my guess with your problem start. With all the heavy rain we had lately maybe some water got in the camshaft connection. It's a bugger to get to but unhook it and apply a little dielectric silicone grease and do the crankshaft sensor while you at it. Merry Christmas
