2019 ford explorer 3.5L Put a new fuel pump on and after driving it will not start again until it cools off. After it cools it will start and run fine. Just acts like it’s not getting any fuel. Any thoughts?

 

Since you would need a capable scan tool to check fuel pressure and chances are you don't have one ,sooo,
You can check for spark and if you have it we get back to pulling one spark plug after it won't start and from the appearance of the plug would tell you if wet, yes getting fuel, and if dry no fuel, and we go from there. Can you do this?
