87 Mazda won't start

87 Mazada 626 2L 5 speed. I do not think the battery or the terminals are the issue.

Upon turning ignition to accessories, all oil/engine lights on dash come on as usual. However, when you turn the key as to start, all lights go black and no power is provided to engine. Lights will remain black until you jiggle the battery cable, and then oil/engine lights come back on (until you turn the key to start).

It is also interesting that when you shift gears (when the oil/engine lights are on) that will also kill the dash lights similar to as when you turn the key. Popping the clutch will start the car right up.

Is it possible that there is a short in the cable or a loose connection to what ever the cable connected to or otherwise a bad electrical component. Where and how would I determine what the problems is. Your comments are appreciated in advance. Thanks again.

Don't know if you are still troubled with the problem - but I also had the same thing on my vehicle and the cause was the bad connection to the EFI harness from the Starter motor just below the Airflow meter next to the battery - Check it out. and good luck
