The ZX-7 is carbureted, so you will not hear it until the motor is running. It's not like the ZX-10 and doesn't need to "prime" anything. You won't hear it running when the ignition is on. I would remove the fuel filter and clean or replace it to see if it's obstructing the flow. Also check the pump output by unhooking the output side and running it to a bucket to catch the fuel. A pressure gauge would be better, but this will tell you if the flow is good.

When was the last time carbs were cleaned? If they are dirty, it will be a PITA to start. That would be the next place to look.

ok i got it going, it was the pump, i removed the pump and hooked it up direct to the battery, it coughed and spluttered and then started working, now i have to address the coolant issue lol.

when i got back from a short test ride it was hissing for 20 seconds after i turned it off, the engine was very hot , the coolant level was low but not empty, i dont know if the water was circulating around the engine, perhaps the thermostat has gone, i will look into it tomoz
