If you have a Facet fuel pump, it sure sounds like the notorious "stuck ball" problem, resulting in fuel starvation.

The test and temp fix is simple. Remove the bayonet bottom of the fuel pump. This will expose the bottom of the check valve ball. With a fingertip, press gently on the ball. It should move smoothly against its spring.

if it doesn't move, apply more pressure. It should suddenly snap free with a perceptible "click" and operate smoothly afterwards. Close up and retest.

Unfortunately, this is only a temporary fix, as I have found that once the ball starts sticking, it will do so again. Only permanent fix is a new pump.

Anyway, try it. Its easy and only requires a few minutes. Let us know how you do.
