Good night
My car is been giving problems about 4 months ago but its been in and out the mechanics. The problem is that the car when is cold start normal but when reach the operational temperature and you turned off after 45 minutes you try to strat the car again and won't start. The car make the starting but do not make the combustion in the engine. Is like the gasoline is not reaching to start but it have pressure. The fuel pump, the crank and camshaft sensor and the computer were change. Also de injectors were clean the oxigen sensor are good I have no others ideas. When the temperature of fhe car goes down its starts again and also if you put some gas direct in the engine also start. Does not give any codes.
Please help me I have no more ideas

When this happens, does the engine even try to start? Have you confirmed that it is getting spark and fuel?

Let me know.

If it is getting spark and fuel, it should run unless it's getting too much or too little. Has the coolant temp sensor been checked to make sure it isn't sending a false reading to the PCM?

The CTS is a guess at this time. I have had vehicles not start or just run really bad with no trouble codes. If the PCM receives a signal from the CTS, it doesn't know if it is the right or wrong signal. The last issue I experienced was a van with no codes. The CTS was telling the computer it was -40 degrees F. As a result, the computer dumped fuel to make it run in those conditions.

It is just a thought. If you have access to a real time scanner, check the CTS signal to determine if it is working properly.

Using a scanner, he can see the temp the sensor thinks it is.
