Sorry, that's not the solenoid for the CAV pump. It's this:

And you can see it's not in the hundreds of dollars as reported. If it's in fact in need of replacement, it's an easy job.
A reliable test to eliminate the solenoid as the problem is to unscrew it from the pump, remove the plunger and spring, and screw it back in. If the problem disappears, the solenoid is the culprit. You can run the engine that way until the replacement part arrives, but you'll need to shut it down at the injector pump. The shutoff lever is on the top of the pump throttle housing, it's in the upper left corner opposite the throttle cable, and is a short lever with a spring. Just rotate the lever and wah-lah: Shut down.
I had one go intermittent- how sweet, it would just shut down, no warning. Started right back up. Disconcerting.
Priming, as Ski indicated can be a bear. Put throttle wide open, hand on the ready while cranking. Be careful you don't load up the exhaust with water, you may want to close the thru-hull to prevent that until it fires.
There are two priming ports on the pump, on is on the side of the throttle housing, the other is on the circumference of the distributor section of the pump at about 10 o'clock looking at the fuel line end of the pump. It helps to purge them if the pump gets air.
