I have searched my butt off and can't find much definitive info. I have an 03 F350 SRW with just shy of 110k miles. It cranks fine when cold and runs beautifully. Whenever I get to my destination and turn it off, it wont start for at least a minute of cranking. It runs fine once it does crank though. I have only had the truck for about 3k miles. It has had its HPOP replaced at around 70k miles according to the oasis. Love the truck! I just need it to start when its hot.

My mechanical abilities are lacking when it comes to the level of skill it requires for these motors. How much am I looking at getting charged to correct this issue?

Thanks again,

Devildog....sounds like your HPOP again. Most likely the STC fitting ...there is a new solid part that fixes this problem. This is something that you can do. Do your research (read the Tech Folder) at the top of the list. Good luck. You may even be seeing a DTC if you hook it up to a scanner. That will help you narrow it down a bit. Also, look up "HPOP" or "STC" in the search tab...you would be surprized how much info there is on this subject. Good luck.

 

Devildog, could be the hpop again but not a stc fitting. 2003 had the early style pump that had a different discharge tube that did not use a stc fitting because the line bolts to the top of the pump. No start hots are unusual on 2003's but I have seen the braided lines under the valve covers develop leaks. Also any place in the straight oil rail that requires a plug has an o-ring that could possibly leak.

A good diesel mechanic using compressed air in the high pressure oil system should be able to isolate the leak.

 

I agree that it sounds like a high pressure oil leak, but the 03 does not have the STC fitting.

Other possibilities:

Good question, so we can start with known issues of the 2003 model year, check the ICP and ICP connector. Read Here The ICP on your 03 is located under the turbo and not the easiest to get to but you can.

Hard start when warm usually points to a high pressure oil leak in the 05 & 06 models with the snap to connect fitting. It is possible since your high pressure oil pump was replaced that you could have a fitting (o-ring) showing a high pressure leak when warm.

Those are the 2 areas I would check or start looking at. Just my 2 cents worth.

 

I agree with the stc portion of the post. Not sure about the rest.

 

Don't everyone type at once .........................

 

Geeezz you guys are fast..... Look at the times when we all posted.

 

WOW guys! This site is awesome!!!

I think this would have to be a record. I have been reading the tech folder. There is quite a bit different on the 03s it seems. Thanks for all the info. I will slowly but surely look at all the recommendations. Am I going to be doing any harm by driving it like this? It is my only means of transportation. I don't even notice it if I don't take a lunch break. Thanks again for all the replies.

 

Won't do any harm but the problem may develop into a complete cranks no start, so just be prepared.

 

Hey Devildog,

I am having the same problem with my '05 F350. In trying to help my mechanic figure out what is wrong, I came to this site, and I'm getting lots of good info. (Thanks all you other guys for your replies to Devildog!)
My question is, should you be seeing oil leaking, because my truck isn't showing any sign of a visible leak. The other variable with my truck is it happens when the fuel is down to a 1/4 of a tank. Is this just a coincidence?

Thanks,
Shilohsara

 

How old are your batteries? I had a similar problem when warm. I thought mine rolled over good enough I was wrong, a new set of NAPA batteries 880 cca seem to have solved it. It really spins fast now and starts crisp.

 

brand new.

I had them checked and everything is good to go. Still runs great and has absolutely no problem starting when cold. Once it is warmed up though it wont start to save my life. I noticed yesterday that it is black smoking a little more at full throttle than I am used to seeing. Not sure if my mind is playing games on me or not. I still haven't taken it in yet. It should go in the next few days though.

 

Shilosara, the oil leak from the hpop is internal...you should see any external oil drips....everything stays in the valley...different from the old diesel where both the filter and pump were external...and so if there was a leak you discovered it on your driveway...of course being external easier to get to and know when you had a problem...now with everything in the valley of the engine...things are different. Do you think you have an HPOP leak?

 

Hot crank no start on an 05 is probably the STC fitting on the HPOP. There is an updated part to correct it. You should not need an HPOP. If it's always happening when you get down to 1/4 of a tank of fuel, then when it happens, pull the lid from the secondary fuel filter under the hood to see if it has fuel in it. It may just be a bad sending unit in your fuel tank giving you an incorrect reading.
