Fuel Pump Issue?, walbro whine gone... Options

[elvasoshexai]

for some reason, when the car is running, i noticed that i cannot hear the loud whine of my walbro fuel pump anymore... but my car still runs... is it messed up?

actually.. damn.. i just noticed that when i turn the key to the 'on' position, i can't hear the whine either...

i'm assuming the FP is still working since i can drive the car... but its not pressurizing or something so not making the whine?

based on zeitronix readout, af ratio ranges from 13-16

used to get lower readings between 10-13


and actually i can slightly still hear the FP whine.. but just today it all of a sudden became a lot quieter




also, so where do u stick the multimeter to check voltage?
