My dad’s truck stalled out on him and now it won’t start. Starter just cranks over and over again but the engine won’t start. It’s a 2005 Ford F-150 SuperCab with the Triton V8(4.6L Displacement). It’s stuck in the middle of the road now but will go down tomorrow to see if I can get it to start when it’s not -10F. Just wondering if there are any suggestions of what the issue could be.

There are many things that could be causing problems. You will have to determine if it’s lack of spark or fuel. Once you determine that we can try to guide you toward a diagnosis.
Was able to get it back to the house but had to jump start it. On the way up it really struggled. I had the pedal mashed and it was just cutting in and out as if I was intermittently punching the throttle. My dad thinks it could be the battery, and wants to replace it anyway since it’s still on the factory original battery. I don’t think that’s the issue but it could be that simple.
Tomorrow I may play around with it since I’m stuck home with a possible MRSA infection. I looked tonight and it looks like the fuel rail doesn’t have a stem on it to diagnose the fuel part like my older Jeep has. It has new spark plugs, and the wires come directly from what looks to be some sort of computer controller, wires look fine and don’t seem to be rotted or broken. No check engine light and no codes either. I bet the thing will nag though if one tiny problem with the emissions happens.
Don’t know if it could cause something like this but the ABS light has been on for a while, could that screw with the engine electronics and cause this sort of stuff?
Also alternator seems to be working great and puts out between 14-15v steady, depending on engine rpm.
I think you may have a partaily frozen fuel line. Try putting some isopropyl dry gas in the tank. Let it work for an hour or so. The methonal stuff doesn’t work as well. It may be that simple with the low temps we are having.
My thoughts were that it could be the fuel filter. I had Chevrolet 1/2 ton van that had the same issue and it ended up being the fuel filter. It’s worth a try. Good luck!
you say the generator output is good correct? Have you checked the stand alone voltage of the battery? is is it over 12.4 V? if not one or more of the cells is bad and time to replace. I think Eric has a good video on youtube on it. Is the check engine light on? if so, best to have the codes read at Auto Zone or some place so you get an idea of what is happening, in terms of possible misfires.
Fuel, Air, Spark, Compression and Timing. One of those has to be off
It really could just be frozen fuel. As far as I know, it’s not good to leave the gas tank almost empty.
Well, frozen might not be the best choice of words. If it’s cold outside wherever you live, don’t leave the tank almost empty.
It would be very unlikely that it’s the battery.
Much more likely that it’s a fuel related problem, maybe due to the cold weather.
I’d make sure it has plenty of gas and make sure the battery terminals and cables are tight and clean. The fact that it started from a jump could be due to the terminals– there’s more strain on the battery in the cold. A bad connection I would think may cause sputtering as well if the sensors aren’t getting right amount of juice.
Keep us posted please.

I borrowed one of my friends code readers and drove around while monitoring the RPMs. The idle seemed really low, even after the battery change. So I opened up the throttle body and cleaned it, also replaced the air filter, now it seems to be idling a lot better but haven’t had a chance to test it again against cold weather. If throttle body cleaning happens to be to no avail fuel filter will be next.
The new battery did fix one thing though, when it stalled shortly after it started right back up. Been three days since throttle body cleaning and no stalling since then.
