I have a 2016 7845R that normally starts in a fraction of a second, barely time to let the key off. Intermittently, and now always, it won't even begin to start. The cranking sounds good and strong. This last time it started instantly but then quit in about 2 seconds and will not restart. My first hunch was no 12v to the fuel cut solenoid, but it looks like it's doing what it's supposed to.
Here's what I've check so far:
1. I spun off the fuel filter and everything looks clean.
2. I opened the bleeder on the bottom of the fuel filter. No water, air, or sediment came out. It streams out faster with the electric transfer pump running.
3. The fuel cut solenoid on the injection pump looks like it's pulling correctly with the key on. The injection pump is a "Motorpal" brand made in the Czech Republic. I suspect it's a Bosch design. (It's also not the one illustrated in the service manual.)
4. There were no leaks before I checked the fuel at the filter.
5. The filter housing has what seems to be a hand pump. After a few pumps with the electric transfer pump running, the transfer pump sound changes from clicking to nearly silent.
6. Fuel tank is half full.
I have the service and owner's manual.
What's are my troubleshooting steps from here?
