Andy,
You say it 'appears' ready to turn over but does not. What do you mean by 'appears'? If you turn the ignition switch to start but it doesn't turn over, the fuel pump is not even on the list of possible causes. Number one would be battery. If you get a fairly loud and rapid clicking noise but the engine won't turn over, that would indicate a bad battery, connections, or very low charge. If you get NO noise whatsoever, check the battery connections themselves both at the battery and the starter, or the starter solenoid may be frozen (corroded) in place and unable to engage the starter motor and contacts. Turn on your headlights while trying to start it. Do they dim considerably and still not turn the motor over? Probably a bad starter motor or Bendix drive. Try a few of these things and get back to us with the results.
