Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi and Welcome to Just Answer! RPM reading of 167 is OK
diesel engines do not have issues with Crank sensors gas engines do.
Fuel rail pressure should go to and above 800 psi
Have you tried starting fluid? use brake cleaner spray as it is less volatile then starting fluid for diesel. if you have not try it as you observe rail pressure! let me know!
your rail pressure is good, it sounds like Engine computer, and Fault codes?
I can not find this code in my data base, is there any description of that code?
it is okay, please do so. I may not replay right away because I am at work, but will do as soon as I see your message.
I thought you say say there are 1000 psi when cranking, please check all 15 amp fuses in front right side of engine compartment. If you have blown fuse, please let me know what is the fuse number
well in this case I guess your ECM is having internal failure(injector driver)
it is located in passenger side will well, between fender and vehicle body, remove wheel well cover and you will see it
check all power and ground supply, if all good you need another ECM.
You're welcome, please let me know what you have found! Best regards
The ECM has to cloned if used or programmed if new, otherwise vehicle will not start . check all powers and grounds before replacing it.
This is not so easy, you need to find someone that can read and copy the the original computer and transfer this info into the new one. ther is a company called bba reman. contact them at
Best of luck, Pavlin!
