My 2007 Toyota Highlander Hybrid didn't start this morning! I turned the key, and everything went off. I could hear the electric engine trying to start, but that was it. The fuel engine never started. The lights and dashboard went back on, with the "Engine" indicator on. It sounds as if the main battery was OK, but the electric engine battery is dead!? Is the electric engine supposed to start the fuel engine?

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.
Sounds like a bad battery. If the battery is OK than lock and unlock your Toyota with your fob. If it is still dead than take the better terminal cables off and touch the negative and positive cables together while both are disconnected and away from battery terminals. Should reset your anti theft system. Connect the cables back and try to start. again. If no crank likely bad battery. If battery is OK but no crank then it is the starter.
Check for spark and fuel. When you turn the key on you should hear the fuel pump in the tank for a few seconds till the pressure builds up. When you crank the engine there should be spark at the plugs.
That sounds really steep to me. Id ask them how they are justifying it. I have replaced a Highlander HV inverter before and It only paid about 4 hours, its not difficult at all. Yes, I am Toyota hybrid Certified.
You have to pull off all of the rear interior trim panels to expose the hybrid battery. On the driver side of the HV battery, there is a large plug in device, that looks like a two-pronged plug. Extract it, and the HV battery will be disconnected.
