Your question as written makes no sense. You made an earlier post 10 minutes before asking "How do check fuel pump is working".
Although badly written, (How do you check that the fuel pump is working?), I can answer that.
In the engine bay on the fuel rail there is a port that looks like a tyre stem called a Schrader Valve. You connect a fuel pressure gauge to it and test the fuel pressure when turning the engine over to start it. The pressure should be 44-50 PSI.
You really need a Hybrid specialist for that one . It could be the engine seems to run but it's just the hybrid system turning it over , sounds like it's running .
The computer monitor the system and recognized a problem. After so many years and miles the battery may go bad and computer send a massage. Or something ales is bad. Hard to guess w/o scanning for code. stop buy to dealer or mechanic wit good scanner and read the code.
this fan noise may be the coolant fan doing the job of cooling the radiator when there is no air flow through the radiator as in standing in a line or at lights. IN a drive through line you would have the window down and so the noise came to your attention when the fan cut in. However have it checked out by an accredited repair shop to put your mind at rest.
the aux battery is bad its uder the hood the generator does start the gas engine but you left the dome light on or something like that it will not turn on or switch to ready mode
take the inner pannel off and there will be two clips,screws ors bolts just simply remove theese and sisonect wiring it should just push inward and come right out.
