My car starts fine when it is cold outside, but when it is warm it is hard to start.
Scan data if engine temp. is normal if ok see if there is engine faulty code.
hope it helps

Sounds more like your ignition module is getting hot and not working. I'd go there first before replacing the ECM. You can remove the ignition module and most NAPA stores have the ability to test them for you. Make sure they test it at least 5 times. This way it'll simulate starting and stopping.

yes...first...how old is the battery?? you have 3 options...the battery is bad, the alternator is bad, or the serpentine belt is bad...most auto parts stores will check your battery for free while it is in the car....otherwise take it out and bring it in to have them check it...

Check the cold start injector useing a digital multimeter with a bar graph. Unplug the injector wires and insert the probes into the wiring plug, crank the engine and the bar graph should pulse if it does remove the injector and with the wiring reconnected and the injector held over a suitable container crank the engine and observe the spray pattern. If insufficient replace injector. This should be a starting point at least

Please check the fluid level in the power steering pump. After putting on a new hose the fluid may have traveled through the system and you may need more fluid.

It is a default setting in the vehicles computer. When the remote start is activated it only enables the engine and the accessories are on standby until the key is inserted. As of now I am not sure of a change to this default setting.

No codes. It mostly happens when it is warm outside. The engine does not have to be warm for this to happen. I have replaced the gas cap, and plugs and wires. Thank you for your input.
before starting scan data of temp. sensor if it out of range
whatever the outside temp . the temp sensor should match outside temp example if outside is 30 c then the temp sensor should be near 30c
I checked the temp, it matched with outside temperature. No fault code.
