Help 8.3 cranks wont start!!!

Hi all- my Bus wont start!!

I need help- I live in Central MI area- I have a 97 or 98 Tc 2000 ( title says 98 but has 97 dashboard and mechanical 8.3) rear engine TC. We have had the bus 2 years, has always been trouble free- starts at -2 below runs great no smoke 200K, allsion 3060. Anyway it has sat for about 4 months ( we use as a farm coordination unit in summer ( sits plugged in not ran) Went to start it- cranks will not start NOT even any smoke like it has no fuel (1/2 tank)!!
I have read other article on Google and others start then stop. Mine will not start at all- only cranks. This bus usually starts after the most 3 cranks (2 seconds in dead winter after sitting a month.
We are planning a trip in 2 weeks ( great - bus wont start) I am a long way from a shop so Towing is going to break me just to get to a shop
Anyway PLEASE HELP
Other info
1. We went to Nebr in March - drove thru snow ice ( salt ) I was bad did not rinse off engine- the battery Disconnect very corroded hard to turn- but everything powers fine. I don't know if this corroded lift pump ( I don't even know if I have lift pump. I think I found bleeder nut - steel tube with apparent rubber fuel tube going to it.

If anyone can help greatly appreciate- replying to my post would be great calling me would be fantastic. number is 616-755-6241
thanks
David

Ok, remember the first rul- Don't Panic!!

Is the fuel shutoff working properly? Diesels usually stop because there isn't fuel.


also-tap on the tank and make sure it has fuel.
Gauges are notorious for being utterly horrible.

check if you have any emergency hatches/latches that aren't secured.

oh-I'd check all battery connections, all chassis grounds, all engine grounds and make sure they are clean & tight

If you think you may have corrosion issues, take a look at the chassis ground to battery connection. There should be a connection at the starter that branches to the block and the frame. Your starter is working, so that's probably good, but the frame and/or block grounds are often the culprit(s) in ECM/TCM issues.

Don't forget to disconnect your negative terminals before taking the leads apart. Hate for you to arc weld yourself to your bus...

Also this little tidbit from a thread on irv2.com:
"There is a Starter - Relay Solenoid somewhere in the engine compartment or close by- Just trace the small wire on the Starter Solenoid back to it- This also activates and locks in the Fuel Shutoff Solenoid when the starter is activated."

In this case, it ended up being a broken terminal at the starter relay, but there might be something in there to point you in the right direction...

The thread: Cummins 8.3 Starter wiring schematic - iRV2 Forums

Note: They never actually post the schematic.

As mentioned, check the solenoid on your fuel injection pump. Since you have a rear engine, have someone turn on the key while you watch the IP to see if the solenoid moves.

and remove any jewelry...
may sound funny, but I was working on a lawnmower battery, and it only takes a split second to arc your wedding ring and a wrench to make a nasty burn all way around your ring finger

I have proven this message!

After my lawnmower jolt, I remembered a guy years ago......
