slow to start (sometime)
i have a 01 F-350 with 57,000 miles, within the past month it has had problems starting. 9 times out of 10 it will start no problem, the 1 time will not start right away, it cranks over fine,odd clicking coming from behind the radio. i changed the fuel filter, cleaned the battery post and load tested . still you never know when it's going to start. I own 3 powerstroke SD's and this is my main service truck so it has to start when i need it!!!
My new F-250 SD will be in Sept 25th, can't wait!!!

Have you checked the air in the tires?
Sorry, I couldn't resist.
You actually have about the same mileage and years on your batts as I do. I have a company car and don't start mine as often as I should. 12hr days man. Anyway, mine has begun to crank a little slower now after sitting for 5-7 days. It will always start but I'm not happy with it. I know there has to be one of 2 things happening:
1: Slow drain on batts
2: They're nearing their service life.
I have checked the voltages and they are all within tolerance. I even had them on a charger to recondition them about a month ago. They will start it now, after running a short while, it cranks like a champ every time.
Sooo, I believe I will be in the market for some new ones before the year is out because it is not even cold here yet. Shazam.

I would normally say CPS but that clicking behind the dash has been turning up a lot here lately. Some kinda relay I believe. Stand by for others or start the painful search process for the needle in the stack.

Is there anything in common with the times when it won't start? Such as first thing in the morning, or only when it's hot, or only after being shut off for 5-10 minutes....anything in common with the no start condition?

check to see if u have a battery drop from your positive termenal to your batt case..that will tell you if u have a cracked plate inside your batt.....my truck was doin this about 4 weeks ago .....and i did a volt drop test and i had a 9 volt drop from posi terminal to case..and i replaced batt(s) and it works just fine now..thats just my in put

I had the same problem with my '99 and discovered that the off time that it would crank but not fire, the voltage was dropping so low it was causing relays under the dash to drop out (thus the clicking.) In my situation, the vacuum pump was running dropping the voltage down from its normal 14 volt range to about 9 volts or so even before I hit the starter. I haven't determined if I have a loose wire or a faulty vacuum pump, but if I simply wait until I see the voltage climb back to 14ish (pump off), the truck starts without issue every time.

it has never failed to start when the engine was hot, only in the morning or afternoon after it has sat for 8 to 10 hours. I don't think it's the CPS i've had those go out before in my other trucks (allways a spare in glove box). i have gotten in the habit of turning off the ac, shutting the door, cycle the WTS 2 or 3 times, can hear fuel returning to to the tank in the bed, wait for chimes, vac pump to turn off before i try to start. and if it doesn't start, you crank on it 5 to 10 times before it bust off.
I've got a new set of batterys in one of my other trucks , been thinking of swapping just to rule out a possible bad battery.

Difficulty in starting, after sitting for a while, is one of the first signs that the low pressure oil pump is starting to go bad. Have you noticed whether the truck doesn't seem to run as well as it used to? It may not, but if it does, that's another indicator of the LPOP going south.
I'm not saying that the LPOP is definately the culprit, but it's another possibility.

I do believe I just learned something else from this great site. Right here in this thread. Don't know if anyone here has seen any of my posts about my radio acting screwy, usually in cooler weather when first being started in the morning. A humming from under the dash. Well, cooler weather equals heater control switch being left on overnight. Heater control switch being left on equals vacumn pump running immediately and I guess causing maybe getting weak relays to click on and off. Does this make sense to anyone?

harvey,,,,, i've already thought of the HPOP being low of oil,, would the low pressure pump be the problem with only 57,000 well maintained miles.
I tested the batterys with my Snapon battery tester
