so you turn the key, does the engine spin? do you hear the starter click? do you hear the starter turn?

i meant to say trying to start. it turns over but when it actually turns over its makes the sound a starter makes when it goes out. could it be the harness for injectors n coils? cuz they r kinda corroded looken.

when the starter goes out it clicks or makes no sound...

so the engine is turning right? this means your starter is fine but you are lacking spark or fuel

is it turning really slow/ slowing down before kicking over? your battery terminals not being tight enough or corroded will cause the starter solenoid to drag on its way in and out. how old is the battery also?

idk how old the battery is. but the car is turning over jus dying as soon as it starts pretty much. thinkn maybe the harness for coils n injectors maybe. idk tho its got me stumped. it didnt do this til i put the injector in.

so the car starts, then dies? defineitely not a battery or starter issue, most likely a spark or fuel issue

check the ecu for codes

clean your connections and reconnect them, the old corroded connectors have a tendancy to loose connectivity when fiddeled with
