Thank you BFL13
I will print this out and take it to the Mechanic
Those steps may clear it up, unfortunately the mechanic will tell you they can't guarantee it, so you still won't have absolute peace of mind.

But you won't be totally out of luck if the truck tends to start after it's sat a while and cooled off. I guess, for the next few weeks try to avoid hard left turns while out in the boondocks.



Neither turns were hard left turns, I had plenty of room to make the turns. Yesterday I was not really making a turn as I just pulling over as the truck was stalling, trying to run

Had to get a new starter for the E350. The Bendix (sp?) went out on it they said. Made a noise like that ISTR. It spun like crazy but no cranking.

Had that throttle body clogged up on my 2003 Chev truck. It sort of got worse and worse without me noticing except at high revs pulling the 5er up-hill, it pinged some. Then it died while driving. Ran battery down. Good Sam tow. Got battery recharged, truck fired right up. Later got it in, and they said it was the throttle body which they cleaned. No trouble after that.

Ford has a box that plugs into the OBD port on your vehicle. It sits on the floor and records everything the ECU sees and does. When you have the issue, you push the button on the box and it locks in the previous 10 minutes worth of data. My BIL is a Ford service manager.. That is what they use for intermittent problems.

My 99 F350/V10 did something similar. Turned out to be the fuel pump in the gas tank.
When it wouldn't start you could hit the gas tank with a board and then it would start.
Or just wait until it cooled off and it would work. Not a cheap repair.

Sounds to me like a failing fuel pump. I spent a lot of time trying to find the problem and changing parts. What I learned from this experience is fuel pressure does not predict a failing fuel pump. If the fuel pump is bad (totally failed) it will but one that is working intermittently testing the volume of fuel(gals/min) is a better test. Have your mechanic look up the specs for your vehicle and have him do a flow test, you don't want to be caught on the road with a failing fuel pump especially in the summer when everyone is traveling and you can't find a shop available to fix it.

I agree on failing fuel pump.I had a Chevy do the same.Would not start with ether due to not building fuel pressure in the fuel rail..It died on road two times before finally figured it was fuel pump..After new fuel pump installed all has been good

For your Ford truck there is an inertia fuel shutoff switch located in the passenger footwell on the right side kick panel that will shutoff the fuel to the fuel pump in case of an accident or sometimes a bump in the road. But if it is triggered, you have to manually reset it by pressing a button and not waiting awhile like you have been doing. Maybe not your problem but I just thought I'd throw it out there for your info.

We are talking about a 17 yr old vehicle with 17 yr old "technology".

2003 that is actually OBD1 with OBD2 port connection, in essence it is a "hybrid", OBD2 readers can connect and they can read codes, however with the OBD1 system it is connected to has very little diagnostic information that is monitored and reported.

As long as there is no CEL or MIL light, there is no "codes" stored and most likely no "pending" codes since OBD1 has a lot less sensors to report on. Even "live" Data is pretty sparse on vehicles of this age making trouble shooting a lot harder.

Even on OBD2 vehicles you should NEVER fully rely on the codes or live data and just randomly throw parts at it..

As far as a local Ford dealer trouble shooting a 17 yr old vehicle, yeah from my experience plan on spending north of $4K and multiple trips and lots of parts thrown at it AND STILL NOT FIXED!!!.. That comes from experience with a 2006 5.4 which does have full OBD2!

I ended up fixing the original problem (not the same as the OP) with a CAN OF THROTTLE BODY CLEANER AND A RAG! Got tired of NPF (No Problem found) and $4K poorer I did an internet search of the syptoms and found out the throttle body was gummed up.. In the mean time the dealer damaged a cat converter, changed fuel pump, changed plugs and darn near cost me thousands more when I discovered a LOOSE PLUG!!!

My advise to the OP, IF you love and are attached to your truck, you will want to fix it yourself, otherwise I will recommend saving your sanity and a lot of money and buy a NEW truck.. The 6.2 V8 gas engines are awesome and from what I hear, the new 7.3 gas is even better..
