I'm not familiar with Kwik Way. However, hydraulics are hydraulics no matter what.
Oil comes from the tank to the pump to the control valves to the cylinders which picks up the load.
Make sure the key that drives the pump isn't sheared. I'm assuming there is one.
You can tee in a gauge onto a pressure line to see if you are getting pressure out of the pump.
Is there a filter on the tank line, "suction line", feeding the pump? Could that be clogged?
If you take a line loose at a cylinder, does any oil come out?
Are your control valves 1 lever you control (pilot "joystick" style) or two levers you work back and forth (forklift style)
