Odd No/hard Start Condition

Same situation has happened 2x to me and I can only find one common denominator.

The end of my driveway is a slope, not very steep.

I typically don't park the truck in that part of the driveway but when I do it seems to cause a no start condition. The last time I got it to fire by WOT and cranking and it made all sorts of smoke and angry idle.


My only crazy theory is that the HPOP reservoir drains when I park on the hill and the oil has a hard time filling the reservoir when parked there. I have had times where I will crank 8-10s figuring that the LPOP will fill the HPOP reservoir but its usually to no avail.

Needless to say I park it somewhere flat and it starts with no issues. I have no idea if thats the cause but its a theory. I have AE in the mail now so I kind of want it to happen so I can see what the heck is going on.

Now I cannot confirm nor deny this, but i've read a similar thread where the guy states that a shaft seal is bad in the hpop, and when parked at an angle, it drains causing hard/no start. I'm not intimately familiar with how the hpop is constructed. Hope this helps. Btw, you are not the first person to post this condition.

Up until recently I would have and have said it was not possible.
My contention has always been if the seal leaked enough under gravity conditions then it would not be able to hold enough oilpressure in to crank and run when the truck was faced the other way.

However a mechanic whom I admire and respect on another forum said he had come across one himself and had heard of other from techs he trusted.

We compared notes on our testing proceduers and found we both ran the same tests but got different results. Mine was a pinhole in the oil pickup tube in the pan. His was the bottom o-ring on the pump to reivoir pick up.

Two sample tests really are not enough to draw a definate conclusion. So all I can say now is it can happen. This is a very rare instance it took 4 years before I came across one and only that one, I have worked on several thousand since the first 6.0's came out and only saw that one.

If any other techs come across this and would be willing to share their test proceduers and results I would like to hear them. PM me at any time.

Thanks for the responses guys, I have no idea what goes on.

But trying to isolate situations and conditions related to them this is all I could come up with.

ICP reads about 600ish at idle when its running, have no idea if this is related.

When your at the end of your drive way and this happens are you nose down or nose up? I know some think I'm crazy but I can make this happen on mine any time it's nose up hill for longer than 4 hours. I didn't see what year your truck was but I have only heard of it on the 03 early 04. there is a tec on anther forum that has me convinced that mine is HPOP or the o ring under it I am hopeful that I'll make it until spring don't want to do it in the snow,,,

Had this happen on mine last weekend for the first time. Sat for three hours on a slight nose up incline, took three long cranks for it to slowly sputter to a start and idle with a big cloud of smoke. Have been glued to the FICM volts, IPR/ICP readings since then. They've all checked out and can't repeat it at all, but have been maintaining level parking spots since then.
