Here are a few pointers from a former pressure pump tech. Usually no spark is caused by the low oil safety system or spark plug wire shorted. This system will prevent the engine from starting if the oil is dirty or contaminated with gas. Try disconnecting the oil sensor and the kill wire from the coil. If no joy re-install the old coil and test without oil sensor connected. The spark coil can be tested with a growler used to test armatures. Sometimes a shorting sparkplug wire can be found by pulling the starter rope in a dark room and look for sparks jumping to metal. enjoy

Kohler command 20 twin engine - no spark


If there's no spark, then either the spark plug has come into contact with gas, or the ignition coil is bad. Try either replacing the spark plugs, or removing the old ones and seeing if the tips are damp.

If replacing them doesn't work or the plugs are dry, then try replacing the ignition coil.

Honda 3000 will not restart


hello this is a common thing what you do is drain all the gas out of tank and carberator take off the cup and drain it to becarfull because the jet may fall out take a dry rag and stick it in the tank and have a flat face screw driver are something to clean the tank put fresh gas in it and it should fire right up if not take out the spark plug but leave it hook and pull the string to see if you getting fire if not it is your coil that is bad if you see rust on the coil where the fly wheel is take a sand papper and sand it real good now when you put it back on set your screws and then take a dollar bill put it between the flywheel and the coil thats the space you need so it would send fire tighten your screws and that should do it if not buy you a new coil if it is giving fire some time you still have to chang your spark plug i hope i helped you have a bless day

Press washer starts an runs for 5 min then shuts down/ restarts in a few min then shuts down again


It sounds like could be one of the problems listed below or a combination of those things.

1) The exhaust is partially blocked. Check the screen covering exhaust port for carbon and dirt build-up. The high-speed exhaust air must pass freely.

2) Gas is not flowing freely to carburetor > under gas tank, find the rubber hose connected to carburetor. Pull off rubber hose and make sure gas flows freely. You can use this hose to drain gas tank of old gas, and then put in new gas.

3) Carburetor is partially gummed up and engine cuts off when gas flow slows down. Check small engine repair shop or auto parts store for gum out, and don't store engine with gasoline in the tank. Or put additive in gas when storing machine.

4) The choke is letting in too much gas or not enough gas. Try different adjustments. The choke-lever on our power washer got so bad that we could not set throttle at full open or the machine would die. We still use the machine at 2/3 throttle.

5) Dirty air filter that won't let engine breath enough air to keep up with combustion. Take off air filter and see if problem persists.

6) The spark coil is going bad?? Change spark plug to see if problem persists. Is spark plug wire pushed all the way on the spark plug?

Bought unit new last summer. Used it once last summer and once this year. It started fine both times. Today, it will not crank. I have replaced the spark plug, checked the air filter (it is clean), gas...


Unable to crank? Do you mean unable to start?

If you leave gasoline inside tank over long period of time, that will 'gum-up' and ruin carburetor.
To prevent problem, put additive in gasoline or empty gas from tank:: under gas tank should be a hex bolt that holds up gas filter > loosen bolt and drain gas.

Starting the engine:
Take off air filter and spray WD-40 directly into carburetor.
Start engine, engine should fire on the WD-40 accelerant.
If engine fires but does not keep running, try spraying WD-40 into carburetor continuously to see if you can keep engine going.
If engine stops each time after it no longer gets WD-40, then carburetor is bad or gasoline not getting to carburetor or gasoline is bad.
Try fresh gasoline.
Do not turn small engine on side or upside down or oil will get into carburetor.

Check gas supply: Go to gas filter under gas tank. Pull loose rubber hose that connects to carburetor and see if gas comes out rubber hose.
If gas is flowing to carburetor, then carburetor is gummed up.
Small engine repair might suggest 'gum out' or have other suggestions ... but you may need a new carburetor

If engine will not fire on WD-40
If engine will not fire on WD-40 at all, then spark coil may be bad or exhaust port is clogged
Check screen that covers exhaust >> is it covered with carbon and dirt or can air pass through it easily?
Check spark
Remove spark plug
Put spark wire back on spark plug
Hold spark plug by rubber spark cap so hands don't touch metal part of spark plug
Touch spark plug threads against hole where spark plug was removed >>> metal to metal so it conducts electricity
Pull start cord and look for sparking between spark plug threads and metal of engine (don't look at the spark gap ... look where metal meets metal
If you have no spark, the spark coil is bad >> time for estimate from small engine repair shop or get your part number and order replacement

Was running fine till ran out of gas ........fill tank up ...try to restart it .......wont start replaced plug ........still no go .


Recurring issues with honda engine no start. Engine was thought to be out of gas however engine was actually shut down by oil alert. Check/change oil to reset, or unplug wire from oil alert and check engine. Vacuum in fuel system due to faulty fuel cap. Loosen cap to allow air in tank. Water in fuel. Water will condense out of the fuel in fuel container and will be introduced into tank. Water is heavier than fuel and will enter carb bowl. Check engine fuel tank with flashlight for signs of water, remove fuel bowl (shut off fuel) and clean. Spark plug is rarely issue, however could be wet from too much choke. Good luck

Pressure washer will not start


Do you get a spark? Take out the plug and leave the wire attached. Hold it close to the metal frame using INSULATED pliers. Have someone try to start it. Can you see a spark? Is the oil OK? Some engines have a low oil shut off.

Replaced stop switch and it still won't shut off!


While attending college, I worked at a tool rental center and learned many tips and tricks from the mechanics. The problem that we heard the most from customers was that the machine would not start. Your your machine at least starts and runs fine, however will not shut down with the factory kill switch. Many times when replacing the mag. (spark coil) the kill wire would rub against the flywheel and break or over time the conductor wire will break inside the insulation. If you kill switch only has one wire, then all the kill switch does is short the mag to ground. Simple test is to remove spark plug, re-connect wire to plug, touch plug to engine and pull rope to observe spark, then short the tab on the magnito to ground, should be no spark. If you still have spark, coil is defective however good enough to run engine. Kill with choke or pull wire. If no spark with test, make new wire from tab of coil to kill switch or any switch that will short tab to ground. Good Luck

Unable to start gas engine on a NorthStar pressure washer


Disassemble and clean the carb. If it ran briefly with the starer fluid then gasoline is not coming through the carb.
