2005 Sterling: Detroit MBE 4000 wont start. Any Ideas?
My 2005 sterling wont start. It cranks but wont turn over. It was working fine until I changed the oil and filters, then tried to turn it over. Heres what I've done:
-Changed the fuel filter
-Changed oil and oil filter
-Checked oil level
-Changed fuel/water seperator filter, cleaned the bowl.
-Changed Air filter
-Open lines running to fuel filter, there is fuel going to through the lines when crank.
-Bleed the fuel
I've used starting fluid and it only runs on that then shuts off. any Ideas would be much appreciated as I'm running out.
Have you checked all your fuses and circuit breakers? Especially any of them connected to the ignition systems, fuel systems and engine in general.
How is your coolant level?
I assumed you prefilled your oil and fuel filters prior to installing them.
Make sure you didnt accidently knock any sensor wires off or loose when doing your service. These cars are very reliant on the sensor info anymore.
If you cannot find an electrical problem and there are no fault codes, I would look at the fuel pump drive. There is no keyway or spline on the shaft. The drive gear is held on and driven by the torque on the bolt holding the gear on the shaft. Your Sterlng dealer should have the service info on this.
Go to: and look for Service Information Bulletin 16-MBE 4000-04 and download the attachment.
The bolt torqued to 22 ft-lbs is the bolt the backs off. Some fleets just remove the bolt, loctite it and put it back in. You might feel better if you replace it, but 22 ft-lbs is not going to stetch the threads.
make sure the fuel filter is installed right , make sure its the right filter.
Sounds to me like there is some air in the system. I don't know anything about the Euro engine, but I would guess it's the same as the American version. Take your fuel filter back off and look inside to see if there is any fuel in there. Fill it to the top and reinstall. Make sure the seal is good and the filter is seated properly on the mount.
After a diesel engine gets air in the fuel system, it will take a lot of cranking to purge it.
If the fuel system has a hand pump mechanism, use it to help prime the system.
I do not know if your engine has a intake air preheater or not, if you do you should disable the preheater by pulling out the megafuse before you use starting fluid.If you do not have a hand pump to prime the fuel system one way to prime the system is to apply about 10lbs air pressure to the fuel tank thru the overflow/vent hose and loosen the drain line fiitting till you get a nice steady stream of fuel without any air. Let us know how it all worked out in the end, whether your car wasn't starting because of air in the fuel system or whether it was the fuel pump drive, as jlk had posted.
