My son's FL2 2008 SD4, auto model is refusing to start after standing with the ignition on for about 20 minutes. Have done all the diagnostic tests and the only code that came up once was a "crash" code. The guy reset this, but it still doesn't budge. Fuel pressure is about 250" - can't find what it is meant to be. We have cleaned the crank sensor as well, not luck either.
Any great ideas?
