Q: Car won't start on first attempt, takes several tries the vehicle will turn over 2003 Toyota Sequoia

Hello - most likely, your hard starting is caused by a malfunctioning fuel pressure check valve, or fuel pressure regulator. The fuel system is supposed to hold a small amount of residual pressure in the system for faster starts. A leaking check valve makes the fuel pump work harder, and run longer when cranking, before adequate fuel pressure is available for the injectors. I recommend a hard starting inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs. The " engine continues to crank after I release the key" is actually normal on most new cars now. Turning the ignition key to the "Start" position, even momentarily- then releasing it, initiates a "start sequence", which is computer-controlled, and runs the starter for a few seconds on its own. This is a precursor feature for the "auto stop/start" feature (at stoplights) more and more cars have now. Nothing to worry about.
