Hey, everyone. I recently bought a 95 ZX7, and everything was fine, then I went out to ride it, and it had some problems starting. I figured it wasn't getting fuel, or the carbs were dirty. So, thoroughly cleaned the carbs, and the hoses. Nothing clogged, and the carbs were actually fairly clean. When i put everything back together, I went to turn it on.. and... The fuel pump kicked on, but never stopped trying to build pressure. What could be the problem?

The pump should shut off automatically when there's sufficient pressure (like 3 psi) in the line. The first thing I would check is whether or not you have a sticking float that's allowing fuel to be pumped directly into the intakes and thusly the engine. Sometimes when carbs are completely dry, a float can stick and when the float needle doesn't seat, the pump will continue to run due to no backpressure on the line.

Okay, so I re-checked the Carbs. Floats are fine... Any other suggestions? I'm getting frustrated.

So, no fuel flowing into the engine? It must be going somewhere, unless the pump isn't working at all. Maybe the problem is on the other end and the pump is sucking wind.

Like, maybe the outlets on the tank are plugged, or there is a hole somewhere?

So, I disconnected the hose from the outgoing spout of the pump, turned the key... And Nothing. Fuel pump was on, but nothing was coming out. It squirted a drop, but then nothing. New pump?

Check all the lines, and the filter.

To test the pump, use a bucket of fuel (kerosene is a better choice to be honest) and a couple of hoses. See if it pumps anything. Then kink the hose and see if it shuts off if it is in fact running.
