Bad cell in battery?? Blown fuse?? Bad starter or contact AT starter?? Seized engine?
DON'T NEED manual to TEST fuses.....TEST ALL!!! Then wiring broken or bad ground(s).
VOLTAGE at ground wire with high beams on???
Compression/valve timing ?? Describe how verified if answered........PLEASE.......
Clean the throttle body.Electronic throttle- key on engine off have someone or something depress the pedal to open throttle body for cleaning do not force open by hand.
May need reprogrammed.
PSI -#?- high side & PSI # low-side??? need pressures , and how much it varies. ALSO What KIND of noise??? GRINDING/scraping???
then swap position of #5 coil(label them before removal!) with another cylinder like #2or#3 and see if the misfire goes with coil......
What is fuel pressure doing from key on engine running to 'start' then after it stalls? IF you answer , give PSI readings from a gauge , not just a yes it's good!...Ignition switch failure ... next thought. other guesses which can be tested/verified before spending money on wrong parts...Mass air flow meter(or leaks in intake hoses) and idle air control valve.
