David, there is a buzzer that sounds off when there is an oil pressure problem. I had it happen to me. In my case it was with a brand new engine. I replaced the rear pressure sensor and also put the two pressure lines on correctly( the mechanic helper got them switched backward) and the problem was solved. There was a buzzing but the problem was most definitely NOT the fuel pump. John Rodgers 88 GL Driver "MOST,DAVID" wrote: > I heard a buzzing while idling the engine earlier today.
