Why does my car take multiple times to start?
Hello – most likely, your hard starting is caused by a malfunctioning fuel pressure check valve, or fuel pressure regulator. A leaking check valve makes the fuel pump work harder, and run longer when cranking, before adequate fuel pressure is available for the injectors.
What would cause my car to have a hard time starting?
If your vehicle won’t start, it’s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you’re dealing with a battery or an alternator problem.
What causes long cranking?
When an engine cranks for a long time before it starts, either spark or fuel is missing or weak and each has its own reasons. A bad coolant sensor, a bad throttle position sensor (TPS), a bad fuel pump or a plugged fuel filter can all cause a lean condition causing long cranking times.
Why does my car take longer to start in the cold?
The chemical reactions inside of batteries take place more slowly when the battery is cold, so the battery produces fewer electrons. The starter motor therefore has less energy to work with when it tries to start the engine, and this causes the engine to crank slowly.
Can fuel pump cause hard starting?
2. Difficulty Starting. Another symptom commonly associated with a problematic fuel pump is difficulty starting. A weakened fuel pump can cause the vehicle to take more cranks to start than normal, and in more serious cases may even cause the vehicle to require multiple turns of the key before it will start.
Is it bad to keep trying to start your car in the cold?
It’s a common occurrence as low temperatures can cause your car battery to produce less current, making it that much harder for your engine to turn over in the morning. The cold can also stop your engine oil from flowing as well as it should, which puts even more strain on the battery.
