I am troubleshooting my ZG327. Seems to be having a fuel issue. Is there a way to test or check that the fuel pump is operating correctl?

Assuming it's a' black disk like pump' with a line from the tank, one to the carb and a 3rd to the valve cover....
... remove line going to carb,point into a pop bottle, crank engine for 30 seconds.Gas should 'pulse' out into bottle. Engine may actually start with gas in carb !!!.

A common failure is the vacuum line from valve cover to pump.
