![]() This test helps you determine if the issue is related to fuel injectors, a fuel pump, or a fuel filter.Ĭonnect a fuel pressure gauge to the rail and check the pressure. ![]() To diagnose bad fuel injectors in your Toyota Celica, start by performing a fuel pressure test. Keeping an eye on your vehicle’s check engine light and addressing any potential electrical issues promptly can help maintain optimal performance. Inaccurate signals to the fuel injectors can result in engine misfires, decreased power, and reduced fuel efficiency. Looking for a damaged wiring harness is the first and easiest step to take if you suspect your Celica’s fuel injectors are failing. Faulty wiring or damaged electrical components can cause the injector to send an incorrect signal to the engine control module (ECM), leading to a poor fuel-to-air ratio. Electrical IssuesĮlectrical issues with the fuel injectors can also hinder your Toyota Celica’s performance. When the injector doesn’t close properly, excess fuel may enter the combustion chamber, creating a strong fuel odor and potentially wasting fuel. Leaking InjectorsĪ leaking fuel injector can cause an array of problems for your Toyota Celica. This buildup can eventually restrict the flow of fuel, leading to a reduction in engine power and acceleration. This odor can be a sign of a damaged fuel injector that needs to be addressed.Ĭauses of Bad Fuel Injectors Clogged InjectorsĬlogged fuel injectors can lead to imprecise fuel distribution, subsequently affecting your Toyota Celica’s performance.ĭebris, dust, or contaminants in the fuel can settle and accumulate in the injectors. Unusual Exhaust SmellĪ bad fuel injector can cause an unusual smell from your exhaust, as excess fuel or unburned fuel may be released through the exhaust system. This can result in sluggish performance and a lack of responsiveness when pressing the accelerator. Your Toyota Celica may experience poor acceleration if the fuel injectors are not providing the proper amount of fuel for combustion. In severe cases, this can prevent your engine from running altogether, leaving you stranded. Engine StallingĪ faulty fuel injector can cause your engine to stall, particularly when idling. This can make it more challenging to start your vehicle, especially if the problem persists. If your fuel injectors are clogged or damaged, they may not provide the necessary fuel to start your car’s engine. But, you’ll definitely notice the lack of power. Typically, as the engine RPM increases, you won’t be able to “feel” the engine misfire as much. This can lead to a loss in power and acceleration, making it difficult for your vehicle to perform at its best. Misfires and Loss of Powerīad fuel injectors can cause misfires in your engine due to an incorrect air-fuel ratio. When one or more of the fuel injectors aren’t functioning properly, the ratio will be off and fuel mileage suffers. Your Celica’s PCM is constantly adjusting the air/fuel ratio and timing to get optimal combustion. It may feel like the engine is about to die as the PCM (powertrain control module) struggles to maintain idle speed. That is to say there will be a sudden drop in idle speed. It’ll feel almost exactly the same as if it had a bad spark plug. With a fuel injector that is not properly atomizing fuel properly, your Celica is going to have a difficult time idling. This occurs because the injectors are not providing a consistent flow of fuel, causing the engine to operate unevenly. When your Toyota Celica has bad fuel injectors, you may notice a rough idle. In some cases, you may notice a bad fuel odor at idle or experience engine stalling.ĭetecting these symptoms early and addressing the issue can prevent further damage to your engine and keep your Celica running smoothly. When a fuel injector isn’t functioning properly, it can cause problems such as misfiring cylinders, the check engine light, or even a vibrating engine. When they leak, they can really cause some issues
