Has anyone encountered issues with warm start because of the electric water pump? My waterpump is throwing codes 2E84 Missing pump and it's intermintently failing causing fan to go on full speed. The thing is the car doesn't start (cranks but doesn't fire) when water pump turns off or if the coolant temperature is above ~85 C degrees. When it cranks but doesn't start, the cooling fan is blowing on full speed and running for 5-10 minutes. If I try to start the car after fan turned off, it will start.

EDIT: If I disconnect the coolant temp sensor, the engine fires up immediately when hot as well.
