All M pumps should use 8-10 ATDC engine timing (compression stroke).
Follow the instructions found in the manual. Navigate to the Resources >> om606 >> om606 Manuals menu item. Open chapter 7 of the manual and follow the instructions in manual 07.1-8410. Again, timing needs to be 8-10 ATDC.
Pump locks can usually be found on eBay and are in expensive
We do not install injection pumps or perform work on customer's vehicles.
The Dieselmeken elements have a lifetime warranty as does the labor to install them

Customer is responsible for shipping charges to BenzForce for warranty work, we will pay return shipping.
We will always try to assist in troubleshooting issues but most problems come down to improper installation. Stroke cycle, fuel supply, air and timing are the most common issues but we are limited in what we can do without being physically present.
Most common issues: Air in the hard lines, restrictor banjo bolt left off the engine side of the pump, wrong stroke and wrong timing.
om60x M issues: Pump not timed appropriately. Pumps should be timed to 8-10ATDC on the compression stroke.
Another problem that happens from time to time is that the pumps are dropped or jarred so hard during shipping that the pins slip out of the rack. If things are not working right, you can take the side cover off the M pump and verify that all pins are in place. Below is a picture of pins that have slipped out. This is not a big deal, it just needs to be popped back into its holder and the side cover reinstalled.
