SOLVED! Broke down New Mexico

A bad crank or cam sensor can definitely shut the engine down, but it is still strange that when this first started the fuel was low in the filters, and you have yet to see any white smoke when it cranks with the inline pump added. Let's hope some codes will show with the reader.

Thanks Bob. Will see if I can jumper the coolant level sensor just for fun. Cliff, hahahah. Don't jinx me. Walter, if the crank/can sensor were toast, would it shut off fuel to the injectors? If so then no amount of priming or fuel would get
Me white smoke I would guess right? The fuel filters being low (they were about an inch down from the top) is weird to me.

An inch down from the top is not a lot, I had the impression you were down much more. The electronic controls & sensors are top candidates now, in my opinion, but those with electronic Detroit's would have more experience with such things (I stayed mechanical

) My trucks have been shut down by sensors, buy they were newer Volvo's and Internationals.

I recall my low coolant issue in the drive way after setting a while, it would consistently start run perfect 10-15 seconds maybe and like clockwork shut down. fwiw
I may have missed it but has there been mention of the fuel sensor n the filter housing 2nd believe. ? curious with the low amount in filter also, but
But anyway the cam sensors! no connecto no run o. (nice tech usage turning motor over without startup on most, in a shop setting)
so with some carful hand testing the front pulley sensor as in the book, resistance ohm's maybe checked here with the cen tec. not sure spec across with it un plugged.
with more carefull test possibly an ac, or book spec. test reading can be had while sensor connected by way of back side testing the connector, with fancy paper clip if avail, this is its pickup test from the tone ring/or whatever they call it.
To close for lunch these dang 500pg books I remember buying different manufactures, these are only part of it then there's parts, and omg Electrical. well guys before this here internet cd stuff this was the prize, consider for just a moment in 86 bought my first jd book at 600buckaroos again only 1 of the required books. In the shop I needed different books for each different model tractor, loader, roller, grader, vehicle so paper gold they were.

good day

WE ARE UP AND RUNNING. I finally checked 12 V power to the actual ECM harness connector not the power connector the power connector has always had 12 V but I guess that 12 V feeds the injectors. The actual power to the ECM the 12 V wasn't making it all the way to the ECM because the relay in the back died. So I did not have 12 V to the ECM via pin 439 so I jump or 12 V to that pen and she fired right up. Thank all of you for your help. Been a long four days. Ken Arnold has been on the phone with me several times a day, cliff has facebooked me and you guys all just helped me so much to chase this down. I also know a lot more about my coach electrical system now. Wow! On a sidenote this appears to be a similar fix that beachfinn (Sami) had to use on his MC 12 a while back.

Awesome!
I was just sitting here going over some things in my head and looking back at notes from problems I've had in the past trying to see what we were all missing!

Glad to hear yer up and running!

Thats why the Aliens wouldn't let you go because your ECM ( Electronic Communication Machine ) was not getting through to them. HA

Congrats Dave5Cs

That's got to feel good, real good! Awesome - have been following this closely - most of it was above this dinosaur but was really impressive watching it unfold in real time. Great job guys! Have fun Scott!

chessie4905 · October 28, 2016, 11:11:33 AM

That's got to feel good till you sit down and total up the cost for this adventure. Wow! I feel for you.

Debo · October 28, 2016, 12:01:11 PM

Congratulations! I've been following this like everyone else, and I'm glad that it came to a positive outcome. I wasn't any help on this one because my beast is mechanically injected, but the combined knowledge of this board is outstanding. A great group of folks willing to help a fellow bus nut get back on the road. Awesome.

Same here. Sorry about the expenses you incurred so far (including loss of work) but at least that's the end of it. Good luck from here! BH

Finally ... the feel good moment.

Note to self: Put those spare relays I bought in the tool box.

DoubleEagle · October 28, 2016, 06:17:02 PM

One little relay brought the whole bus down, paint the new one day-glo orange with two eyes on it! There is much to be said for being self-reliant and knowing as much about your bus as possible, but it is also true that your willingness to share your troubles with us (repeatedly) generates a lot of good responses. You must feel very relieved, why, it's almost worth the $1300 tow, right?

DKO · October 28, 2016, 06:20:32 PM

Very glad you are going again, Scott. We are all breathing a little easier now.
