I just bought a new to me 2006 Ford F250 6.0L Crew Cab and I ahve driven many diesels before but for the life of me cannot remember it taking so long to turn over when I turn the key.

The glo plug light goes off and I turn the key and it tries turning over for a couple seconds and then finally fires up. Is this normal? I don't really remember the delay in past vehicles. Sometimes it takes 1 second and other times it takes 4-5 seconds. It almost sounds like it doesn't want to crank. New batteries and everything checked out before purchase.

 

Is it more prevalent when it is colder outside? I notice that mine may take a second or so longer when the outdoor temp is down. Every now and then I need to turn the key off and back on to get her to turn over.

 

It usually takes a little longer when the truck is warmed up. I have only had it a week and don't know if I am just being paranoid but we did have temps in the 30s and 40s this week but not that cold. I could understand first thing when it is 30 degrees but the other day I was driving all afternoon and ran into the shop and came out and it took 3-4 seconds. Am I better to keep the key cranked or just turn back to off and try again after so many seconds.

 

You may have glow plug issues. Also - I do not think it hurts to crank continuusly for 3-4 seconds (versus crank 2 seconds, stop, crank some more, etc). If it is really worse when warm, it may be an issue with a developing (very minor) leak in the high pressure oil system.

 

my 04 takes about that long to start too. it's like it needs 2 complete revolutions to fire. it's done that for ever. as long as she keeps starting i'll keep smiling. is it not cranking, or just slow cranking over?. after re-reading your post it sounds like youv'e got bad batteries. when you say it doesnt want to crank does the starter not engage?.

 

i am having the same trouble it is my batteries i am certain of it the originals in it cost 80 bucks a pop so i am just gonna go with the optimas. it statted shifting funny also and the dealer told me it was because the batteries were weak. they had a good run. 6 years original batteries what can i say.

 

Your probably due for batteries. Mine are just four years old and one is taking a dump. I would go with the Optimas also but there are always issues with the placement of the battery posts. I need to take some more measurements before make a final decision on which battery to do with. I need to make a decision soon. I'll post up with my findings. You had better luck than I with the stockers. Are you thinking red or yellow tops?

 

Just because they're new batteries doesn't necessarily mean they can't be weak or bad. Did you have them load-tested? Don't wait too long if it is batteries/alt. as it will take out your FICM and that will set you back over 1G.

 

The starter does engage and it starts to crank immediately but takes a few seconds to turn over. The batteries are new and have been load tested as I had the dealer show this to me before it came off the lot. This weekend the temps were warmer and it only took 1-2 seconds to fully turn over. I am thinking it was more of the cold starts and me being use to a gasser turning right away. I will keep an eye on it. Thanks for all the help.

 

I've had my 03 for about 10 days now, and it does the exact same thing. I have a slight oil leak coming from what appears to be the driver's side of the block, and I haven't pinpointed it to a bed plate or something else, although looking at it, it appears to be coming from the bed plate. (I really hope that's not it).

Mine also stumbles a bit when it starts if it's cold. Almost like it's slow to wake up to run. Other than that, it runs like a scalded dog and has leaps and bounds more power than my old 7.3.

 

From what I hear, this should help cure the FICM deaths happening due to the last Inductive Heating flash...

09-7-11 6.0L DIESEL CALIBRATION UPDATE - VARIOUS ISSUES

Publication Date: April 3, 2009

FORD: 2003-2005 Excursion
2003-2007 F-Super Duty
2004-2008 E-350, E-450, E-550


This article supersedes TSB 07-5-4 to update the calibration level.

ISSUE:
Some 2003-2007 F-Super Duty vehicles, 2003-2005 Excursions and 2004-2008 E-Series vehicles, equipped with a 6.0L diesel engine may exhibit hard start, no start, white smoke, lack of power, running rough condition after cold engine start up, or diagnostic trouble codes (DTCs) P0404, P0470, P0611, P1260 and/or P1378 issues. Refer to the Calibration Content for information detailing specific vehicle content by vehicle application and model year that is being addressed by this calibration update. This article includes previously released calibration content that improves injector performance in cold engine operation and additional calibration content improvements for specific vehicle applications.

ACTION:
Reprogram the fuel injector control module (FICM), to the latest calibration using IDS release 60.05 and higher. The powertrain control module (PCM) and transmission control module (TCM) will automatically update after FICM reprogramming if they are not at the latest calibration level. This new calibration is not included in the VCM 2009.3 DVD.

CALIBRATION CONTENT

The PCM and FICM calibration update contains improvement actions to address the following symptoms:

2005 F-Super Duty 6.0L:

False DTC P0470 (Exhaust Pressure Sensor A Circuit) due to a freezing condition.
False DTC P0404 (Exhaust Gas Recirculation (EGR) Performance) due to a stuck turbocharger condition.
2006-2007 F-Super Duty 6.0L:

False DTC P0404 (Exhaust Gas Recirculation (EGR) Performance) due to a stuck turbocharger condition.
2005-2006 E-Series 6.0L:

False DTC P0470 (Exhaust Pressure Sensor A Circuit) due to a freezing condition.
False DTC P0404 (Exhaust Gas Recirculation (EGR) Performance) due to a stuck turbocharger condition.
2008 E-Series 6.0L:

False DTC P0470 (Exhaust Pressure Sensor A Circuit) due to a freezing condition.
False DTC P0404 (Exhaust Gas Recirculation (EGR) Performance) due to a stuck turbocharger condition.
False P1260 induced during cranking due to low battery voltage.
Generic OBD improvements including; Mode 1, Mode 2, Mode 4 and J1699 OBD data test results as reported to the service tool.
Previous released calibration content included: 2003-2007 F-Super Duty, 2003-2005 Excursion and 2004-2008 E-Series 6.0L diesel equipped vehicles:

White smoke, lack of power, running rough condition after cold engine start up due to injector spool valve sticking internally during cold engine operation.
No start/hard start when accompanied with DTC P0611 (FICM Performance), P1378 (Fuel Injector Control Module System Voltage Low) and/or all eight (8) injector circuit codes.

 

Thanks 1 Medic,

I have an appointment with my dealer to look at something else so I am going to verify that they performed this TSB. I pulled an Oasis and it showed all updates were current from the previous owner but did not show what the dealer did after the trade in.

 

I replaced my starter last week [faulty solenoid]the new starter cranks the engine twice as fast .Just a thought.

 

you can crank it continously for 15-20 seconds without hurting anything, you should never have to but you can. The injection system on these engines uses oil pressure to operate, therefore if it doesn't see adequeate oil pressure it won't fire the injectors. its pretty normal for it to take 1-3 seconds. its will sound like it makes 3-4 revolutions before anything happens. its normal for ALL POWERSTROKES, even the 95 that i owned for a while did it

 

This doesn't seem normal to me. My 02 7.3 jumped to life when I cranked it. Took all of half a second. This 6.0 takes 2-3 seconds sometimes.
