My 82 has been stalling out lately, so I got a new from mazda fuel pump on which fixed it. Now the car drives fine but stalls at idle everytime. When I turn the key to the acc. postion the fuel pump will make a ticking sound that wasn't noticed before it was replaced. On my other FB which runs perfectly the fuel pump will make a Humming sound when it is turned on, completely different sound.
Any ideas where I should start looking to diagnose/fix the issue?
