I assume you have a Hilborn, or some form of fuel Injection, haven't heard of that brand of pump, and also assume it is a mechanical, rather than electric. Manual pumps typically don't have much pumping power, especially at cranking speed, or being pushed slowly, so that may not be uncommon, as soon as it picks up speed, and gets all the air out of the system, it should at least provide enough volume and pressure to begin a tuning proceedure. While pushing, or cranking if you have a starter, just make sure the throttle is wide open, that allows fuel to fill everything, and of course, if it starts, be ready to get off the pedal. Fuel injection is rather simple, once you understand how it works, and keep all supply lines to the pump, as low as you can, the pump will put out a lot of pressure, but doesn't have much on the vacuum side. Good luck! Bob
