Re: No Start Persistent - D. I. G.
This is exactly the same thing that happened to me when my CPS failed.
Most of them will give you a warning, mine did not. Parked the car at Steve's house one day to grab a car part, got back in, and it was dead. Would "crank" all day long but never fire. We replaced the camshaft sensor front of the motor, behind the belt) and that was a waste of time. Put the OE cam sensor back in, and swapped the crankshaft sensor (back of the motor) with a Bosch unit. Fired up immediately. No problems since.
$45 and my issue was fixed.
