I was driving on the highway and my engine started losing power and eventually stopped working. I still had power and got towed.
Been working on it the last two weekends, I've replaced the starter motor, alternator and ignition relay but it still only clicks. there's also rapid clicking behind my gauges when the key is in. I've checked all my fuses, none of them are burnt or broken. Electrical connections are good and my grounds are OK and provide sufficient resistance. Any help is appreciated, thank you.

Also, when the key is in, the dash shows that I'm in park and D4. Brake, battery and oil light all come on.

?
your issue is that the engine died while you were driving.
Why did you change starter motor?

I May have had bad guidance before, however the engine seems to be fine. I think I'm having an electrical issue, is it possible fuel just isn't making it to the engine? It's not even turning over.
also, for context, I don't know know what I'm doing and a friend is helping me a lot but we need more perspective

Bad battery/ground/alternator/starter connections. Electricity likes clean shiny metal, and a tight connection.
If you have the crappy battery connections that clamp the ends of the bare wires check there for corrosion. One of my cars wouldn't start because of that. Acted the same as yours

thank you for your reply. I've already cleaned out the terminals and grounds throughout the car. I'm seeing good ohms and voltage. I've read through another forum showing something about a bad alarm system? Would you know anything more about that?
I'm currently away for the next few weeks so I can't do much at the moment.

Does it have an alarm system?
it might ohm out on a meter but the current needed to spin the starter is way more than the meter puts out.
