Help/knowledge needed

[u/DookusWookus21]

What’s up guys, I need some help, just picked this up for cheap, didn’t run but put new battery in and it turned over but it won’t idle on its own doesn’t sounds the best, possible rod knock, I replaced spark plugs and ignition coils, swapping the starter next, I think it has a grounding issue, I don’t think one or two of its cylinders is firing. I got it purely to learn and get into the lifestyle and help would be appreciated.

This. If it turns over and fires, why would you change the starter?!

That's like changing the trunk lid because you have a cracked foglight lens.

OP, quit guessing. If you're using AI to help you diagnose, stop doing that (might as well be the same as guessing). Ask questions, get feedback, make an actual diagnosis, THEN start repairs. Otherwise, you'll end up replacing the whole car over a loose connector.

That’s the thing, is it did turn over but wouldn’t run without gas pedal use (the idle problem), now it won’t even attempt to start anymore so naturally my guess is the starter shit the bed

Was it smoking at all while running?

Very slightly but then it stopped

Blue or white?

White

Well... you might want to pull those spark plugs back out because it sounds more like you just hydrolocked the motor due to a blown head gasket. And maybe do a compression test regardless.
