Have a 68 camaro SS clone. Unfortunately, don't know the complete history of what's been done. Please bear with me, I don't know cr*p about this.
When we bought the car, the guy was showing us how you can hear the fuel pump when you turn the ignition to the accessories position - electric fuel pump, right?
The reason I ask is that when I started the car to go somewhere today, this REALLY LOUD "chatter" sound started coming from the rear of the car and continued even when I started driving. Initially, I thought it was a mechanical vibration, but couldn't find anything. A short distance from the house, the car stalled out as I slowed to take a turn and wouldn't start again unless I held the gas pedal all the way to the floor; even then it had to be cranked for a few seconds to catch. To get it back home, I had to put it in neutral and rev to couple thousand rpm everytime I slowed down to keep the car from stalling. Also, the fuel filter has almost no fuel in it, as opposed to normally being 1/2 to 2/3 filled.
Does this sound like a bad pump? bad relay? both?
When I trace the line from the carburetor, it looks like it still goes thru the mechanical pump (small housing, looks like it has a diaphragm in it, low on the side of the engine?). Is this normally done?
Thanks in advance for any knowledge that is shared.
