Hello, my name is***** will assist you.

Has your engine been sitting for some time?

How are you testing items currently?

Customer: replied 1 year ago.
The engine hasn't been sitting at all. Bench tested high pressure pump it's fine. Using a fluke meter to test.

We are a boat shop, just never seen something like this before
Customer: replied 1 year ago.
if I could get the flow chart out of the actual service manual and schematics we would be fine. Tried seloc online but what a 40 dollar waste of time.

Sorry about the delay...

There is not a flow chart in the manual for the fuel pump not running. It does not energize when using the pull start until the second pull.

Have you already isolated the kill switch from the circuit and tested it that way?

Main fuse is good?
