How do you check that fuel is reaching the carburettor?
Turn on the key and monitor the fuel pressure, it should be around 60-psi. If equipped with a mechanical fuel pump, remove the fuel line to the carburetor and connect a fuel gauge to the fuel pump. This should yield a low pressure, under 20-psi when the engine is cranked over.
Why is my jet ski not getting fuel?
First make sure you have all the hoses hooked up correctly. Second it isn’t uncommon for the on/off valve to go bad and restrict fuel. Third the square o-ring on the fuel strainer can go bad allowing it to suck air. All of this can cause no fuel to the carb.
How can I tell if my fuel pump is working?
Check the fuel pump fuse and relay. If both are good, check the wiring to the pump. If voltage is present when turned to “on,” then the pump has failed. Here’s how to swap it out. If there’s no voltage at the pump, check the condition of the wiring and for solid connections.
What’s the best way to test a fuel injector?
Step 1: Turn the car on. Turn the key to the second (ON) position for this test. You want battery power flowing, but don’t want the engine running. Step 2: Set up DVOM to measure DC voltage. Use the lowest range possible if the meter doesn’t auto range. Step 3: Touch the negative lead of the DVOM to a ground source.
How does a fuel pressure test work on a car?
The various fittings connect to the fuel system of nearly any vehicle. When it’s connected and the fuel system is pressurized, the tester displays the pressure in psi on a large gauge visible from inside the vehicle. This allows you to verify fuel pressure while sitting in the driver’s seat, making testing fuel pressure a one-person operation.
How can I tell if my car is not getting fuel?
Usually, you figure out if you have a fuel delivery problem by process of elimination. If you have good spark and clean air, you’re probably not getting fuel. Some folks like using starter fluid as a check.
