Weak / worn starter motor, key switch contacts, or relay. Could also be bad connections.

If this is a 2002 then you might have an electric fuel pump on the frame rail below the driver door. It should run on contact to build up pressure. ..if not no start. ..
If you connect to torque pro app then you can see if you have enough rpm and enought voltage during starting.

Good luck

So .. Voltage was good but i definitely have to get them both tested, and test my starter.

Even bypassing my batteries with another big truck jumping me was not enough to power the starter.

Did almost pick up this morning with my jumper box connected to only the main battery. Did suck the entirely full jumper box in 30 seconds .. :/

Feeling like focusing on the batteries and the starter until i can REALLY clear them out as causing my issue.

There is definitely barely enough power getting the starter spinning in all cases.

Thanks for any details, tips, and opinions !

Thanks !

The fuel pump sounds like working. Is there a way to test it ?

Cant get torque pro on my “dumb-smart-phone” 🍎

Need it though ..

Thank you thank you

Tiny progress made today.

Both batteries were charged over night, at a very helpful person’s place. Was reading 12.89v on the main batterie this morning. Cranked it once, starter was doing its job, heard a couple injectors try to fire, almost picked up. Cranked it again and only heard the starter working, no firing.
Was cranking way better than just after the engine died a couple days back.

Does that eliminate battery and starter failure ??

Feeling lost here.

Next thought is to drop the fuel lines into a 4 gallon jug of fuel .. :/

Any suggestions ?

It's possible your fuel pump is going bad. Remember, pressure is critical, simple presence is not enough. Not sure if the 7.3 PS has the high-pressure oil pump setup on the fuel injection system that the 6.0 PS does. But if so, that's a distinct possibility.

Matt, not sure how you can hear the injectors while you are cranking..
Maybe I have to look back thru your thread but..

What outside temperature?
How long is the glowplug light illuminated?
If below 60 f ..can you plug the block heater in . Should not be required but it sure helps to take another factor out of the trouble shooting.
On the fuel filter is a schrader valve...at least at the older powerstrokes.. here you can measure the fuel pressure ...of course the fuel pump has to be running..
What phone do you have.. getting torque pro would have paid back by now.

Do you have the electrical diagram for your powerstrokes?

Check the relays that turn the idm on.. check voltage while cranking at the idm or fuse box with a multimeter.

If you have a bad starter and it draws to much current and or turns to slow then that all will be helped with a warm engine. So block heater can do wonders.

Good luck
Johan

Thank you.

So if i get a fuel pressure gauge, plug it in the schrader valve, i can know if the fuel bowl is properly under pressure ? How much pressure y’all think i should read ?

Its 53° here, what is a block heater ? How do i plug it in ? I’ve started so easily in colder mornings last winter. The light stays light for about 5-10 seconds. She is a ford 2002, and thanks, i did fetch a 2001 diagram on the forum somewhere.

Apple = 100$ blue drive app ; torque pro apk is not compatible with ��ios :/

Looking for an Elk327 online. Too far from a walmart.

Thanks for helping to keep centered.

The block heater has a 120 vac plug hanging close the front bumper.. normally you do not need it but now that you are trouble shooting you can make it easier on all components if the engine gets warmed up and see if it makes a difference.

Yes Apple...get rid of it...get a uses $40 android

Peary happy about your stance on apples ! Actually dug out an old android friend Gonna make that happen.

Thank you so much for that block heater tips !!! Wondered what those plugs were for quite a minute !

Going to the part store tomorrow morning for a fuel pressure gauge, the fuel line clip tools, and that bluetooth OBD2 scan plug.

Hopefully make some progress before too late tomorrow.

Blessing to all !

In a pinch you can use a tire pressure gauge.. will get a little messy with fuel squirting out. For starting I would not think that the " ford manual spec" pressure is required. So even if you press the center pin of the schraeder valve and fuel squirts out will give you enough knowledge to eliminate that from your no starting list.
I am not sure how long the fuel pump stays "On" after you turn the key.. so this might be a two person job.

Good job on the Apple.

harbor freight if you are near one sells a pretty cheap fuel pressure test kit that works good and has the fittings to screw onto that schraeder.. crankinf fuel pressure is important if tyou can read it while cranking as it lets you know the fuel pump can still pump under the low-voltage cranking conditions and maintain pressure...


torque pro is a big help as at least you can see what the cranking RPM is and the HPOP pressure is while cranking.

Today had the oil flushed. Cranked for a second, then nothing.

Starter tested, and working properly (solenoid & rotor), though under powered by tired batteries that are both charging again for the night.

Will see after the sun warm us up tiny bit how it cranks or not.

Maybe getting that elk327 adapter in the mail tomorrow.

Fingers crossed !

Stay tuned

Okay,

The 50$ battery tester from oreiley is not better than a multimeter to actually know how healthy the batteries are or not.

My friend couldn’t get my batteries to fully charge, so this morning when he brought them back. One was reading 12.54 and the second one 12.34.

Put them both back in with the secondary one un-grounded so the hot line was hanging any where close to a short.

Had the battery booster on the main battery to give it a kick.

Before turning key in : 12.54 v

Turning the key : 11.04 v

Cranking : went strait below 8v in less than 3 seconds .. no good, right ?

Gave up cranking, sounds like the batteries are shot, both because of not having been properly fed by the loose lugs on the main battery.

Opinions very very welcome

Thank you all

Couple questions ..

Is this starter fluid spray safe to use in a 2002 e450 7.3l with glow plug assist ??

There is that warning on the airfilter waring not to do it ! The bus dealer told me a bit was safe .. so unconfident about that ..

I dont want to brake or blow up the engine .. :/

Also, i finally have torque lite working on a phone. Not quite sure what corresponds to hpop pressure. Is it the same as general pressure of the engine ??

Getting lost here ..

Any help is a lot, thank you

Cant get any phone app to communicate with either obd2 adapters i found .. :’(

Edit: Connection made (had to restart phone & replug the adapter) !!! Hopefully will have some relevant data soon !

Different adapters serve different protocols, and you need to find out which protocol your 02 PowerStroke engine management system uses. I'll put in a call to the local dealer here and see what I can find out.

Are you using group 65 batteries? And two of them.? Do you have aaa. It does not make sense that your battery voltage drops to 8 v in 3 sec. The computer needs 10.5 volt so maybe there is nothing wrong with it besides broken batteries. Aaa can give you a jump start.
I would not use ether unless you know for sure that you flow plugs are broken and you really need to get of the railroad tracks.

Yeah, i stop fiddling around and get two or even four fully changed batteries, borrow them, rent them, buy them and return them, do what it takes to eliminate this as an issue, I know diesels need major cranking power (I did have a f350 diesel once).
It is a simple fix if that is all it is.

Hi, For feature info, should you or other readers need to use a starting fluid, Try using WD-40 instead.
Yes WD-40 Liquid Wrench works very well as a starting fluid!

Enjoy your freedom while you still can!
