I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

I have a Briggs & Stratton gas power washer. This is the 1st time this year that I have used it. I put in fresh gas, hooked up the water supply. The engine started and then quickly stopped. I had to release the water pressure in the hose before I could pull start the engine. The only way to keep the engine running is to hold down the spray nozzle trigger. Once that is released the pressure in the hose builds up and the engine stops.
