Why is my Toyota hard to start?
Fouled Plugs: Spark plugs create the spark which allows the vehicle to burn fuel. Fouled plugs are one of the most common reasons for a hard starting engine. As electrodes wear down, the voltage required to jump the gap to ignite the fuel increases. This can lead to prolonged cranking before the engine will start.

What are the most common engine starting problem?
1. Dead Battery. A dead battery is the most common reason why engines fail to start up.
Why does my car take forever to start?
A: Possible causes: a marginal battery, a poor connection in the starting circuit or starter, a charging-system problem, or the battery is being drained while the car's parked. If this only happens first thing in the morning, a weak battery or a drain in the electrical system are likely causes.
Battery
This is the number one cause of starting problems. It is also very easy to detect because the starter motor does not turn or almost does not (it seems to have difficulties), the lights tend to decrease in intensity.
Starter
Obviously, the starter can also be the cause. It tends to stop working overnight without necessarily having any warning symptoms. The carbons (which are used to transmit current to the moving rotor) end up getting dirty and the starter does not work anymore.
Spark plugs
First thing, change the candles without thinking if they are already a few years old. The role of the spark plugs is to generate an electric arc which will ignite the fuel. If this arc has trouble forming, it will have a hard time igniting, so you have trouble getting started.
PMH sensor
This sensor (located towards the flywheel) which allows ignition timing can cause starting problems.
AAC sensor
The camshaft sensor (located near the top of the engine) has often been the culprit for hard starting.
Other sensors
A problem with the cooling water temperature sensor can interfere with start-up. Other sensors may be involved, especially on modern engines which have them because the computer needs a lot of data to run the engine.
Fuel pump
The fuel pump could obviously be the cause, because if it no longer sends anything to the engine it will no longer be able to “feed” and therefore start. Its relay can also be responsible.
