Crank no start T444E 54,000 miles 10,000 hours, with servicemaxx

[godisgood]

Greeting skoolie people,
God is good but my bus is not /
Can somebody please help me out
I have a crank no; start does anybody know the minimum voltage of the battery? /
I read the codes from the diagnostic button, then cleared the memory.

CODES:
111
144
124
113
323
313
626
525

I read the codes again but nothing came back /
I decided to post this message for a better attack
The motor is a 7.3 (T444E) /
Year of manufacture 1996 + 3/
It used to start and run fine, then ran rough suddenly.
I am not sure where to think /
The text below is from USB link.

THANKS

Couple of low voltage codes, including one for the ICP sensor being low. Those and the low coolant codes are not terribly concerning. However the last two are a bit concerning to me, 525 is Injector Driver Module fault and 626 is PCM Unexpected Fault or Reset.

First and foremost, test your batteries. Verify the connections are clean and tight. The computers will not work without a minimum of 10 or 11 volts, but would much happier with 12. Weak batteries will dip system voltage below what the computers desire while cranking the engine over and a bad alternator could have put you in this position.

Next attempt to perform an injection buzz test. If you got a nice buzz on all 8 injectors, then verify you have fuel pressure and the glow plugs are working. If you did not get a good buzz on all 8, then there is potentially a problem with the harness, an injector, or the IDM itself.

I am no stranger to automation logic and PID loops and error codes but I am really really glad my bus is amechanical 5.9. Good Luck!!

[Simplicity]

Battery Voltage - 12.5 - 12.8. If you don't have a battery charger/maintainer, buy one. Your batteries are not cheap and are key to not only starting your bus, but being charged when doing testing when you have an issue, like now.

Don't overcharge your battery. Having a charger with a maintainer function that is designed for your type of battery (probably a lead acid), hopefully sealed (no maintenance...filling with distilled water). The maintainer should have a multistep charge process that ends in a float step to just keep the batteries topped off.

T444E, I have a diagnostic manual for 1997 - 1999 and another one up through 2003. If you PM me with your email address, I'll send them to you.

Testing - Do you have a 12v test light and a multi-meter? If not, I'd suggest you buy one. Lots of great YouTube videos on how to use them effectively.

Best of luck.

2 Months later…

Thank you all for the prompt responses.

I am slowly taking the steps mentioned to get the vehicle running. However, I am convinced this is a fuel issue due to the mud/glue-looking stuff in the fuel bowl.

I should have checked the fuel filter long ago. Feel free to provide any links to redoing/ cleaning the entire fuel system.


IT LOOKS LIKE THEY HAD THE WRONG SIZED SHORT FILTER IN THERE?


I assumed a bus from a major city would not have had waste vegetable oil-like substance added to the fuel, but that is what this looks like.

Note to self and future readers:


Check the fuel filter ASAP.. (even if the oil is still clear and it runs like a dream.) P.S. There are several different types of fuel filter caps for the T444E (at least 4); some caps are 1/2 inch driver or 1/2 socket to remove, others need a specialty tool... STILL CHECK IT

I believe the worst-case scenario is the injectors got clogged up?

For those of you that are interested in the solution to this problem, I will try to solve it by making it even better than it was and try to incorporate the waste vegetable oil system that I wanted, when I initially purchased the bus. I will have to familiarize myself with the fuel system. Feel free to provide any tips.

1.Drop the tank, look at the fuel pump ..get the goo out.

P.S. In the 2 months that it took me to respond. I "made" a battery that gets around 2000 CCA from Lithium iron phosphate cells. Oh and I adopted another bus.

The last picture is what the fuel and filter looks like on my other working 2001 7.3
