Why does it take 2 tries to start my car?

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 causes a car not to start on first try?

A broken starter is another common reason your car won’t start. A starter is an electrical motor that is connected to the battery. It’s role is to set the engine (i.e. pistons, crankshaft, etc.) If the starter goes bad, the engine will not crank properly or may not crank at all when you turn the ignition key on.

What causes a car to crank for a long time before starting?

When the fuel injectors are clogged up they may not be able to fire at the right time or create an unbalanced pattern of fuel delivery. In such a case, the engine may refuse to turn over slightly but once enough fuel is poured in it may start right up. You can easily check for dirty fuel injectors using a screwdriver.

What is wrong if your car hesitates to start?

A lag between when the ignition key is turned to “Start” and when the starter kicks the engine over could be caused by a corroded or poorly connected high current connection to the starter – say a battery cable connection.

Why does my car sound like it’s struggling to start?

It sounds like you may have a failing voltage regulator or failing alternator. When the alternator is not working properly, this may result in the battery quickly losing charge and the car losing all power. You may also notice a whining sound as a result of the bearings inside the alternator begin to fail.

What causes ignition hesitation?

Common Causes Of Engine Hesitation Include: Clogged Or Leaking (EGR) Valve. A Failing Ignition Coil. A Failing Throttle Position Sensor (TPS) Clogged Fuel Injectors.

How do I test my ignition switch?

Put the ignition key into the ignition switch and crank the engine. If the engine cranks, then your ignition switch is obviously working fine. If the engine does not crank, and you hear a “click” when you first turn the key to the “III” position, then your ignition switch is not the problem.
