Starting issue
Hello all. This is my first post but I have been reading here for quite some time. I have a 99 F250 7.3 6 speed 4x4 with 200k miles and a morning start issue. A couple of days ago I went out to go to work (<?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com
ffice:smarttags" /><st1:time Hour="7" Minute="45">7:45 AM</st1:time>) and my truck would not start. I live in GA and the morning temps have been around 60-65 at that time of the morning (90 by mid day). I do not plug the truck except a couple of months a year so it was unplugged. My first thought was the GPR, since I have replaced it 3 times in as many years (normally during the winter). The next morning I had no luck cranking it. That evening I replaced the fuel filter and cleaned the K&N air filter. It was about a year ago I replaced the <st1:stockticker>CPS</st1:stockticker>. Since it has been running fine from <st1:time Hour="10" Minute="0">10am-10pm</st1:time> I assume it is not the <st1:stockticker>CPS</st1:stockticker>. I plugged it in that night and it started fine the next morning. Last night I did not plug it up and it again would not start this morning. I have a 6 position chip set to the tow setting and have tried cranking it in the stock position as well as the high idle. Currently I have about 2000 miles from the last oil change. The truck uses no oil has not had any other major issues to speak of. I have had my wife go out each day around <st1:time Hour="10" Minute="0">10 AM</st1:time> to crank and it fires off first try. As the temp comes up during the morning and for the remainder of the day it fires off with no effort. When it is cranking while cold there is no smoke and even when it fires up there is no smoke. I was expecting white smoke from previous cranking and no start. Any ideas or help would be appreciated. Any info I left out let me know and I will provide asap.

I suspect,even though their new, your batteries are not up to snuff for starting the motor. Remember, it takes fast cranking
and the heat of compression to get things fired up. Most folks
here go with a high quality battery like the Stock Motorcraft or Interstate Megatrons. She should fire quickly within 5 seconds or so with good strong batteries. Any longer than that and your causing excessive wear and tear on everything.
Diesel fuel washes the lubricating oil from the cylinders and
your starter is taking a beating. I would have them load tested at an auto parts store. Here's an interesting article on batteries to support my argument. Click HERE.

I was directed to buy these batteries by several offer PSD owners in the area. I previously had Interstate batteries that last around 5 yrs. These new batteries turn the truck over quicker than I can ever remember the Interstate batteries, however it has been a several years. I do know for a fact that this winter the Interstate batteries(while they were dying) turned the truck over very slow , but it would still fire. I am skeptical of the problem being the batteries due to the conditions those batteries were in and still cranking it. I agree these new batteries may not last the 5-7 yrs the Interstate or Stock batteries last but right now I feel they are fine. I will have them tested just to be sure. Any other suggestions to help out.

It started fine yesterday morning and then this morning it would not fire. It was a little cooler this morning than yesterday. 72 yesterday morning and 66 today. At these temps I should not be needing to plug it up or use the glow plugs. The batteries checked out fine. I am at a loss to figure out what the problem could be. It has to be temp related as it only happens first thing in the morning. Help...

I'd be inclined to leave the truck at a repair shop so they can attempt to start it and duplicate your problem and then read for any codes and perform diagnostics. Could be a sensor issue or the IPR.
