I'm not getting any fuel delivery to the carbs on the '66 MGB when I turn the engine, although the engine does turn over. The fuel pump does not click at all when I turn the key once. Does this sound like a leak, wiring problem, fuel pump problem, or all of the above? Any suggestions on anything else I could check would be extremely helpful. Thanks in advance!

Aloha Bridanp,
If you don't hear the familiar clicking of your electric fuel pump, that is probably the problem. If the tank was emtpy it would click continuiously, the same if there was a leak on the output fuel line or an air leak on the suction side. A blocked filter or fuel line preventing flow would cause the pump to stop. A few taps the cast iron core of the pump with a wrench will usually get it to run. The points in the pump are probably in need of a cleaning. Also the condenser may need to be changed to prevent pitting on the points.
Safety Fast,
Dave

Tap on the pump, if it doesn't start check the ground wire to the pump. Mine is located on my '72 behind the license plate bolt on the inside of the trunk. The first time I had the plate off, I had that problem and it took me a few minutes to realize what happened. Next check 12 volts to the hot side of the pump. Also the pump points DO get intermittant and will need to be replaced along with the condensor. Make sure you set up the pump like the manual says after you replace the points or you will have trouble getting it running again.
If the tank was empty, the pump would click real fast and not stop. If there was a leak somewhere down stream it would continue clicking but slower than with empty tank. So if it isn't clicking, then you have a problem with the pump or electrics.
