Hello All

I have a 2006 F450 6.0 Super Heavy Duty. The Problem that I am having is when I turn the key it wont crank over. In order for it to start I have to hold the key in the crank position (like i am trying to start it) for about 20+ seconds, and then it will start cranking over. After it cranks over it starts just fine no problems. This only occurs when I start the truck up for the first time each day. After the initial start of the day its fine.

Any Ideas. (FYI I turn the ignition to the on position and just let it set it still takes me turning the key to the crank position and holding it 20+ seconds)

Do the dash gauges light up when you turn the key to the first position?
How long does it crank before it starts?

 

dash light do come on in the on position... have to hold the key in the crank position for 20+ seconds (the glow plug light kicks off at about 10 seconds

 

Do you have a voltmeter?
Try checking voltage at the starter with somebody else running the key. Look for a starter relay as well.

 

We've got a '96 T-Bird that does the exact same thing. Never has failed to start but makes you wonder. I'm curious as to whether this is a Ford thing or if it's not at all related. I realize we're talking about 2 completely different vehicles.

 

What happens if you jump the solenoid at the starter? Does it turn over immediately or is there a delay?
