Why does it build pressure, but when I squeeze the trigger the engine stays at idle?


POSSIBLE this look picture hose coupling with water stop put on the tap side or lime in valves after long time or a nozzle with dirt close beaten
clogged nozzle on the lance

Bypass not working (lyme)
if you disconnect the lance and the handle grip is giving enough water and water comes out then the nozzle clean it with a little paperclip.25944841-me02dbjx1ofpduv3i0g3gg4u-5-0.jpg

Aireated fuel after cold soak


check for a loose fuel line hose/connection that is allowing the fuel to drain back over time and filling the line with air that is causing a air lock when trying to start

99 buick start easy then dies unless you give it gas. then stays running until you go to start again.


Check the fuel pressure regulator. It is on the drivers side, front of the engine near the throttle body. Remove the vacuum hose and see if fuel comes out of the nipple. If it does than the regulator needs to be replaced.

If the regulator is fine than you will need to check fuel pressure with a gauge. If fuel pressure drops as soon as you shut off the car than the fuel pump is likely bad.

I bought a honda pressure washer power boss 3000. I load the gasoline, start the machine, but pressure water is not coming out from the trigger. i tried so many things , but can t get started.


If you are using a water tank for water supply, remove the water supply line from the pressure washer and connect a water hose from a faucet. Turn the water on, then crank the engine. Pull the trigger of the spray gun until water comes out. When then water starts to spray properly the release the trigger, shut engine down with pressure on the line then reconnect the water supply from the tank to the pressure washer. If this fixes the problem then the problem was "air-locked"! Happens alot with new pressure washers that have never been run. If you need any other help, please email me @ davidandlisacampbell@yahoo.com

Take hose and gun off pump.
Start engine.
See if pressure comes out of pump.

Sometimes the problems happen because the gun lever is bad.
Hook up hose but not the gun
See if pressure comes out hous.
These steps will tell you if problem is gun or hose.

Engine runs great, when i turn the hose on it dies.if i hold the trigger and start engine it runs, as soon as i release trigger the engine dies


Make sure thre is no air lock in the system line. So first of all use a clean line to wash off and blow out any dirt in the spray gun.
make sure the engine is having good fuel and power it on to run and warm up . let it run over without any load on it . Now turn the hose on it and power it on slowing, do not stop but keep it running to power spray . The accumulated dirt might come off and make the run smooth after some time.

you may have a broken or sheared pin. That being said I am stepping out of my comfort zone because I do not know that exact model but I have seen it happen to others. Any small engine shop should be able to repair it for a reasonable price.
