I have the car listed above that I just recently bought. I just replaced the alternator. The issue is the fuel pump. I believe idk I'm just looking to see if I'm correct. I spray like a starter cleaner, and it starts right up just feels like it wants to shut off at lights and stuff. If it runs when started isn't the fuel pump good. I mean it must be getting spark if it turns over and runs. What could it be before I buy a fuel pump?

This could be a weak fuel pump, or a vacuum leak and I would even service the throttle bore.
