Hard starts after sitting for long periods
#16
I don't think so, my excursion and F350 both do that, and only the 6.0 liter has longer start times when it sits. A buddy suggested checking the motor mounted fuel filter next time it sits and see if dry of fuel, maybe it's draining fuel off. I'll give it try and see, it does almost seem like it's not getting fuel.

I had an 03 Excursion in my shop about a year ago with the exact problem your describing, turned out to be the front HPOP shaft seal behind the drive gear. the truck had 127,000 miles on it and if the truck sat level for more then 5 days or on an up hill incline for 3 days, it would take 10 to 20 attemps before it would start. since then I've seen this on 2 other trucks.

2005 F350 doing the same thing, only after sitting for a 24 or more period, I changed fuel filters, still having the same problem. I noticed glow plugs cycle way to fast, I also own an Excursion with 7.3, the glow plugs cycle for about 10 to 15 secs, the 6.0 cycles for 3 secs. I started key cycling twice on my 6.0, it seems to help. I wonder if there is anyway to increase glow plug duration?
be advised the glow plug indicator light has no bearing on how long the glow plugs actually are activated for. it is another form of a dummy light just to remind you . the only real way that i have found is by connecting a voltmeter and watching the voltage, while the glowplugs are on the voltage stays right around 12vdc, this is my theory anyway, because when it gets colder here in south florida like 40ish LMAO! it stays around 12vdc longer than the summer, then i notice the voltage climb back up to 13-14dc volts after 1-2 minutes of running.

Are you still under warranty? if so take it in. if not then see if you have the latest flash. they will only charge you 1hr labor for the flash, it seemed to clean up alot of bugs with mine. but long crank times could be hpop stc fitting issue . I had that problem as well.
not necessarily I had a plug on the hpop give out and was losing oil ,the first indication something was wrong was not only the burning oil smell. lmao, but also the extended crank times in the morning or if it sat for 8hrs while I was at work. but ran fine once running

no warranty, but I've been considering taking it in to see if it has the latest flash, I 've looked under for oil leaks, nothing, nor any kinds of oil burning smells. A friend of mine took her '03 in, got the lastest flash for around a hundred bucks, I'll start there. Thanks, I'll up date if that works.

ToolMan05kr, I have had two no start issues with mine over the last year. Both times it was on a Monday (sitting longer periods) and I parked in front of my barn on a hill. Finally had to start it by squirting diesel fuel in the intake elbow. Is there a kit available to rebuild the HPOP or do you have to buy individual components?

not so much the oil leak but there is a fitting that is known on our 05 to leak high pressure oil to cause problems with starting which will only get worse. not saying that this is your issue but it is a known problem with the 05 model year here is some info i dug up on the internet the pdf file link is listed below
ISSUE
Some 2005-2007 F-650 and F-750 vehicles
equipped with a 6.0L diesel engine may exhibit a
hard start/long crank or no start condition due to
low injection control pressure (ICP).
ACTION:equipped with a 6.0L diesel engine may exhibit a
hard start/long crank or no start condition due to
low injection control pressure (ICP).
Use the Service Procedure to identify a fault with the high or low pressure oil system.
SERVICE PROCEDURE
A minimum of 3.5 MPa (500 psi or 0.8 volts) ICP is required before the injectors are enabled. No or low oil in the system, leakage at the injector upper D-rings, high pressure pump quick connect fitting, high pressure pump discharge tube, faulty injection pressure regulator (IPR), or high pressure pump could cause low ICP pressure.
- Perform the revised Powertrain Controls / Emissions Diagnosis (PC/ED) lead diagnostics Section 4, Hard Start/No Start Diagnostic Procedure Tests 10e and 10f. These tests were revised in January 2006. <TABLE border=0 itxtvisited="1"><TBODY itxtvisited="1"><TR itxtvisited="1"><TD width=80 itxtvisited="1">NOTE:</TD><TD itxtvisited="1">THE LOW PRESSURE OIL SYSTEM MUST BE WORKING PROPERLY IN ORDER FOR THE HIGH PRESSURE OIL SYSTEM TO BUILD ICP PRESSURE.
