M925A2 Shutting Off

[Russ Knight]

My truck has started intermittently shutting off immediately after starting it. I can restart it and it runs fine.

Have you serviced your fuel system lately(ever)?

Important portion of above in addition to general maintenance is replacing the flexible lines on the suction side of the fuel system. Really should be considered step 1 on trucks of this generation and age, as it is a known issue, and is one of the causes of what you are experiencing. Also be sure any frame mounted fuel filters are assembled correctly, if present.

This truck was completely rebuilt in 2011 and garaged for the most part until I bought it. It has less than 100 hours since rebuild.

 

[Russ Knight]

And I've put about 30 of those hours on it.

They don't "completely rebuild" the trucks at overhaul. They replace anything that's broken and give it a fresh coat of paint. The advice from others above is excellent and a great place to start.

I certainly will service the fuel system. Thanks!

all filters are available here on steel soldiers less than anyplace else
but you have to ask make pictures

You have no idea what they did and did not do. In addition to that, a lot of mistakes have come out of "rebuilds". Replace the flexible suction lines regardless, as they may not have been changed. New filters, and check tank dip tube. All very common problem areas. If still an issue, move onto OFV (overflow valve) in the pump (externally mounted, simple to remove/clean/test).

I think this truck was rebuilt by VSE. Is that the same place?

No. VSE was top notch, based on the few examples I've seen. I've only seen a very few trucks done by VSE, but a lot of trailers.

This truck was supposed to have been rebuilt by VSE. The engine data plate says it was dynoed for 4 hours when rebuilt. The truck looks new, runs well, very quiet. So far, so good...

Shuts off like you shut the power off or kinda idles low then shuts off? Does it re start right away or cranks a long time then fires?

 

[Russ Knight]

Shuts off like you turned the key off, re-starts instantly.

PCB going out possibly

Or a FSOV issue
