Car won’t start

What is your question?

okay so for starters- yes I realize my car is old and kind of a POS but it’s what I’m working with so let’s just skip over that part. back story- I purchased this 2004 pt cruiser in feb of this year. It had under 100k miles on it and seemingly no obvious issues other than cosmetic. since then, I’ve had issues with it randomly stalling out while driving, rough idle, etc. Since purchasing, I’ve gotten an oil change, replaced the plugs, replaced the coil pack, cleaned out the throttle body, got a new battery, and replaced the MAP sensor. But the problems, although temporarily improved, have persisted. Two weeks ago one day while leaving work- my car wouldn’t start- at all. I had to get it towed back to my house. The next day I messed around with a few things and got it going again. Now, as of yesterday, my car won’t start again. Thinking it was just the battery I hooked it up to a jump starter, no luck. I had a neighbor try to jump it with their car, and still wouldn’t start. Plz help!
