inspect the underside of the power distribution box that has the fuel pump relay for corrosion or loose wires, also check the condition of all ground connections.

Underside looks good. Wires seem all the same and the grounds are clean and tight
Replace spark plugs if not working get new coil packs/spark plug wire/connectors whatever u wanna call it....

Let me ask y'all this. I cleaned the relay box ground really good but it didn't start. I then pulled the relay and put it back in. The car has been starting ever since. Is there any possibility that after the ground was put back I kind of reset it by pulling and plugging relay back in? In other words did I fix the problem by cleaning the ground wire even though it didn't start immediately after?
