I have a 2002 ford focus ZX5 hatchback, I'm pretty sure my fuel pump is giving me problems, trouble with cold start, rough idling, high rpms, but I'm smelling my Catalytic converter. I was told different opinions by diff people, could the catalytic converter cause those same problems? I hope not, its mounted on the front of my motor, there for I'd have to rip apart my whole front end, or i was told it could be my O2 sensor. if its my fuel pump, I didn't see a removable plate under the back seat like in my latter car, a 2001 ford focus (wasn't a hatchback) so I'd either A have to cut a hole to get to it or B, drop my full gas tank (uugh). I need opinions people, please and thank you! Not taking to a shop, the lowest wait time I could find was 4 weeks to get it fixed and I need it done now.
