Hi all,

I have a question. I've seen many posts and much discussion about fuel relays and pumps, but they seem to come primarily from those that have fuel injected engines. I have a carburetor 2.3 engine, and I hear absolutely nothing pump-wise when i switch on ignition. Is this normal? Do carb engines have fuel relays and pumps in the same way. Fuel injected engines do? If the answer is 'yes', then why do I hear no pump noise, yet engine starts ok YET acceleration is terrible (occasional backfire on 2nd and 3rd gear) YET, on a long run i averaged over 30mpg?
