Went to start truck this morning and nothing happened, no noise - nothing. Checked fuses, oil level, tried to start in nuetral. Pulled ignition switch and cleaned it, all looked fine. What relay should I check and how? What other ideas? Both batteries are less than 9 months old.
Engine will not turn over on 2006 Ford F-350 Super Duty
You could still have a bad Battery or 2,. the lights are NOTING compared to the current load it takes to crank a Diesel. Have you tried a tow truck jump? That would tell yo something. You may have a drain that is killing your Batteries.
sounds like a crankshaft position sensor. i am having the same problem with my truck. 06 f350 6.0 turbo diesel
