Bucking and misfiring sounds more like an ignition problem. Check your wires
and distributor cap. Probably ought to change those if they haven't been
changed in a long time. Cracks can let in moisture and cause misfiring.
When you turn on the key, you should hear a whine and then it will shut off
if you don't crank the engine. If you hear this, then your fuel pump is
probably working properly. Need more information for this problem as it can
have several causes.
