Hello! Just ask, why my toyota vios start fine when engine cold but when reaching the normal temp its hard to start. It would be a coolant temp sensor? No check engine light and my radiator fan works very fine and my thermostat is okey. What would be the possible cause to this hard start issue. Thanks!

So, fuel pumps go out when they are hot which sounds like what is happening, but to be sure you can spray a little starting fluid inside the intake when it is starting hard and if that fixes it replaces the fuel pump. Here is a guide to help and I have included how to change out the fuel pump in the images below.

You are lucky because there is a trap door, so you don't need to remove the fuel tank. Check out the images (below). Let us know if you need anything else.
