Battery get drained / ticking sound from ECU HELP!!!!!!!!!!! 94 q45

[Q45dude]

Hello...

this is the second time it has happened. Car starts right away, I go and park somewhere for about 20 minutes or so, then I come back and I get no power at all, like there's no battery in the car. Then after a while, I see the security light blinking and the radio was coming on and off continously and I was hearing a ticking sound from the ECU. Car would not start. Called my friend to help me jump it, now I get full power but when I wanna start I hear tik tik tik tik, car won't start.

Can someone tell me what the heck is wrong?ECU? starter? battery??? Ground wire ???

THANKS SO MUCH...

sounds like something is drawing too many amps... i had the same problem with my car and it was the starter drawing too many amps which caused a plethora of issues including the ticking/dead battery symptoms.

So , how would I diagnose what the problem is?

You have to figure out what codes it's throwing then go from there.

Starter relay?
