2. There are 2 components to injectors, electrical & mechanical. A corroded or plugged injector can test just fine for coil resistance and still be the problem, so don't rely only on the ECM probe procedure unless it indicates defective.
3. ALWAYS keep the fuel tank full during long periods of inactivity. The pump assy can/will rust, plugging the strainers, fouling/ruining the pumps & clogging the filter.
Here's a photo of the one from my Ruby Zee. When it gets this bad, cleaning the tank is part of the fix.

That is really ugly! Years ago we used to put a little kerosene into the tank to keep rust down. Does that work with today's fuel systems?
