Why does my car struggles to turn on in the morning?
There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), malfunctioning idle air control (IAC) valve, vacuum and EGR leaks, inadequate fuel delivery or pressure (clogged fuel filter, injectors), and contaminated or old gasoline.
Why does my car not start in the morning?
My car won’t start in the morning, just gives cranks but if I press gas pedal it starts and have to keep it until engine gets hot enough. then it works for almost all day. and repeat the problem in the morning when I have to go to work. As usual when the engine is cold or cool, it won’t start.
What causes engine crank time to be extended?
Another common reason for extended crank time for engines is a vacuum leak. Engine vacuum must be a sealed system which the mass air flow and map sensors depend on to send feedback information to the main computer which in turn sets the stage for the engine starting sequence.
What kind of car wont start unless you press the gas pedal?
I have a 2002 avalon XLS. In the morning the car cranks but wont start unless I press the gas pedal. After that everything was fine. But recently the problem is getting worse. The car became harder to start although it will start eventually. I have changed the Mass air flow sensor, but did not solve the problem. Any suggestion?
Why is my car engine taking so long to start?
If the engine takes more than 4 seconds to start there is a problem in the way of a leak, low pressure or reference to the computer problems.
What kind of car won’t start in the morning?
Car won’t start in the morning, but it starts perfectly t… Car won’t start in a morning but starts perfectly through the day My car has 137500 miles. My car has a manual transmission.
Why does my Car Crank but not start?
If it cranks but does not start, sometimes a temperature sensor is bad and the computer can’t figure out the proper amount of fuel to inject. Just a little off and the engine won’t start.
When to run the fuel pump before cranking the engine?
Some systems will run the fuel pump for a short period when the drivers door is opened or when the key is turned to the ignition stop before being turned to crank. If this isn’t happening for some reason, you may be having to wait until the fuel pump provides enough pressure at the fuel rail to start the vehicle. My vote is for the injectors.

It sounds like your engine does not have fuel pressure held up to the injectors overnight. The fuel pressure is leaking down due to a bad fuel pump check valve, or the fuel pressure regulator is leaking down the pressure. Have the fuel pressure leak down and pressures checked and the failure isolated between the pump and the regulator.
Why does my car take so long to start?
Another thing that happens with small cars like yours and mine is that it takes time for pressure to build up in the fuel lines. If your battery isn’t performing like it should, it could make things worse. Try an experiment. Turn the key to the “on” position, but don’t start it.
What causes a car to have a hard start?
Thank Kevin. There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), malfunctioning idle air control (IAC) valve, vacuum and EGR leaks, inadequate fuel delivery or pressure (clogged fuel filter, injectors), and contaminated or old gasoline.
What does it mean when your car wont start when you turn on the ignition?
If your battery is dead, then you will be experiencing a rapid-fire while turning the ignition to start your car. This could be due to a malfunctioning or faulty alternator or a low battery charge. Check your battery output voltage with a simple tool, the voltmeter.
