While doing that press down on the aerosol to provide the cleaning solution. Once that’s done, quickly tap the other wire on the positive end of the battery. Ground the injector to the negative end of a 12V battery. Now, you’ll need to connect the injector electrically. You’ll need a cleaning solution, a battery, and a way to pressurize the system.įirst, take out your fuel injectors and attach one end to the nozzle of an aerosol. On the other hand, a clogged injector can easily be cleaned.
If your fuel injector isn’t making the clicking noise you’ll have to replace it. Wet spark plugs are a sign that the fuel got to the plugs.ĭry plugs indicate there was a blockage keeping the fuel from getting in. If your injectors are fine, stop cranking and take out the spark plugs. Repeat this for all the injectors.Ī bad fuel injector will make inconsistent clicks or won’t click at all.
If you hear a constant clicking noise the fuel injector is working. Put your ear to the back of the screwdriver when they are cranking the engine. Once you’re done, ask your assistant to crank the engine. Now place your long screwdriver against the fuel injector. TestĪfter disconnecting the ignition system, locate your fuel injectors. Over time, their nozzles get clogged due to rust or corrosion.Īll you need for this test is a long screwdriver and, as before, an assistant. The fuel injectors deliver the fuel to your engine. Add a product that repairs engine compression. But you can avoid a repair when the offender is a worn-out compression ring. In case the cylinder head valves are the offenders, a garage visit is the only way. However, if the values shoot up, then the issue is worn-out piston compression rings. No change in the values would mean the cylinder head valves are the issue. But, this time add a tablespoon of oil to the cylinders. Once that’s done, take it from the top one more time. Take note of the reading and repeat the same for the other five cylinders. Ask them to stop cranking once the needle on the gauge stops. Next, get your assistant to turn the key while you observe the gauge. Tightening with tools can result in stripping the holes. Then thread the gauge into the first cylinder. The ceramic insulator on a spark plug breaks easily. And then you can take out the spark plugs. Taking off the “Spider” assembly will disable the fuel system.įor the ignition system, you can either remove the ignition coil or the ignition module. To ensure your safety, you’ll need to disconnect the fuel and ignition systems first. All you need is an engine compression tester and a person to crank the engine. You can easily test whether that is the issue or not. If the compression isn’t sufficient your car won’t start. Your engine requires 4 components to start. We’ll be covering every possible issue that could cause a no-start condition. But we’ll be providing a thorough guide to make things easier for you.
