Honda powered gx160 model pressure washer wont start

Hi pulsing is usually a sign of insufficient water flow to the unit.
always get the largest water hose you can for the feed and check to see if your water system can keep up (if it is a three gallons per min machine grab a bucket and make sure you are getting at least 3 gallons per min before you plug the machine in.
The number one culprit for bad flow is the ez hoses or retractable hoses.

Is the ignition switch turned to "ON" . Is it full of oil?

Thanks for choosing FixYa,

The engine should be a Honda GXC160 5.5 Hp.
GO to this website and download your manual:
http://engines.honda.com/parts-and-support/owners-manuals/gx160

You will need your serial number.

If I got the engine model number incorrect choose the owners manual link on the left side of the page and enter your model number.

Being petrol driven, it may have a mercury kill switch which puts a ground on the ignition circuit stopping the engine if you move it. Perhaps for safety in case you overturn the unit somehow.

Hi Greg. Walk into your nearest Lawn Mower parts supply with your engine model number (usually on the recoil) and they will have the replacement part or repair your old one. It is less expesive to have the old one repaired unless the support struts have broken. 2200 PSI should have a Honda GX160.

Here is another source....

They can range from $32.00 to $68.00 depending on source.

Honda PN is: 28400-ZH8-013ZA (do net search this number) Or call your local Lawn Mower repair Supply with the number.

If you have a Briggs & Stratton engine I will need the ENGINE model number off of the air shroud just above the spark plug.

Thanks for using FixYa.

what about the linkage between the governer and the carb. Is that working and not binding?

problem is that u have to use with lowest pressure i believe black tip

It could be several things...oil level, make sure its sitting on level ground...if not did you use StaBil when you laid her up for the season? If not, go to Advance Auto and buy "SeaFoam" and following directions run it for as long as it will run...make sure you have water running through the pump during tests!
Good Luck

Most Honda engines have an oil pressure switch that prevents engine damage due to low/no oil pressure. Make sure there is sufficient oil in the engine and that the wire is connected to the pressure switch.

Is there an oil sensor unit if it is going bad it tells the engine the oil low and engine wont start. I had same problem with my pressure washer, i just unplugged the sensor unit and it started fine ever since
