Loud clicking sound when i try to tunr it over

Boost, hummmmm ?????????????
a charger with a boost button? (big shops have this)
or you mean jumper cable , jump started from a running other car?


my wild guess. is you always start fine, when jumper cable jumped.
this proves, the
battery in your car is BAD or is only discharged.
for 100 years now, same deal.
try a fresh battery off a good car.
works now, so ??? yours is weak or bad!

but started car , is the voltage 13.3. to 15v? a walfart $10 meter.?
no , then the charge system is bad (charge lamp on?)
note, i said system. not a specific part.

if the charge system is failing.?

1. bad battery. tha'ts right alts do shut down with battery bad. (open or shorted battery)
2. loose alternator pulley belt.?
3. bad alternator wires. connections.? or bad battery cables.?
4. scan the PCM most 2007 will report what is wrong with voltages and charge. scan it.

engine rpm way below normal at idle 800 is typ. good. 400 dead wrong.
battery cables bad.
battey cables lugs green with corrosion
someone put the minus cable far end to the wrong part>?
this minus cable has correct spot near the starter.
some fit to block others to stater , bolt or bell blots.
to frame is wrong, seen that , with lazy work.
