If a fuel pump wasnt quite sitting right, could that cause the misfire? on 2000 Chrysler Cirrus

awhile back we put a fuel pump in my 2000 Chrysler Cirrus. It acts like its not getting enough fuel and when it starts it runs rough like its missing. After you rev it up a few times I smell fuel. If the fuel pump wasnt in or sitting exactly right could that cause this kind of problem?

Very doubtful. Your fuel pump is a complete module assembly and just sits on top of fuel tank. At first was thinking possible fuel pressure regulator but i think it's in tank with your module assembly so would have also been new when replaced. Is there a check engine light on? I've noticed these motors have big problem with their camshaft sensors.
