What’s the cranking speed on a Cummins M11?
I have never seen a Cummins have a problem with the ECM, if you are getting power to the fuel solinoid, and 195 cranking speed. You might want to check the wiring plug in the intake cover, is tight If you have it on the computer and it should show the cranking speed.
Do you need CPL for a Cummins M11?
If you call Cummins you can for a lot of the Cummins injectors, just buy a spring. You will need the serial and CPL. If the injectors were working there is no reason to replace them all. That is what I called diagnosis by the ripping and tearing method. It is very expensive

The best way to rule it out is to check if the fuel tank is sufficiently filled, then make sure the pump is delivering fuel and run diagnostics on the actual pressure. Insufficient fuel supply: The engine needs a sufficient supply of fuel to run correctly.
What should the RPM be on a Cummins M11?
An M11 needs 195 RPM cranking to start, it should have at least 75 lbs, going quickly to minimum 140, fuel preasure, you want to test the fuel system while cranking for restriction, filter, fuel lines, ECM cooler plate, as will a plugged suction tube, all will give you a high resistance above 10 is a problem, with a new filter, 6 is max.

Where is fault code 434 on a diesel?
Fault code 434 is low voltage to the ecm on the unswitched power supply. A good place to start is the battery connections. The two 15 amp fuses for the ecm will either be in the battery box or near the ecm. Check the fuses for a good clean connection. Follow the fuse wiring to make sure it hasn’t rubbed through somewhere.

Why does my Cummins M11 have low fuel pressure?
This needs to be done with a bucket of fuel connected to the pump by/passing the ecm cooling base plate.Air will cause low fuel pressure but so will a bad fuel pump.You need the manual says 25 psi to start but all the engine i have checked will have 50 psi as soon as it starts and then to 100 real fast.
