This may or may not be the reason she has decided not to start.

Took my voltmeter and checked. Was getting 12.77v to the front side.

Turned on key and listened for any kind of whirr,click or hummm. Nothing.
Manually felt pump,no vibration.

Disconnected front fuel filter, turned on key.. no flow (other than a bit of gravity).


Should I hear anything or see flow if the pump is good?

Machine was running OK when I used it last week.
Both filters are within a month of being brand new.
I did have a problen with the seat switch, but that's another story.

Help please!

You need to check all the safety switches to make sure that isn't the problem. You said you have power to the pump correct?

Thanks for the replies!
Fixed it.

We had bypassed the safety switch under the seat and must have bungled the job.

Rewired it and she fired right up.
