Hey guys!, I have a 92 EG 4 door sedan civic (153k miles). The car is just simply driving me nuts!
The car doesn't want to start sometimes. More often lately. There is a noise coming from the fuel pump assembly (not the hissing noise). It sounds like those portable air compressors for tires (like "trrrrrrr" or something like that. I can't really tell if it is a fuel pump or a ECU probem. It is reallly , really weird!.

Here is what i've changed so far.

New OEM Main Relay
New OEM Ignition Coil
New OEM Rotor
New OEM Ignition sensor (NEC) (the one inside the distributor) looks like a module.
New OEM Distributor Cap.

Battery, Alternator, Starter, and Ground wires are perfectly. No Check Engine lighted on. NO codes, no stored codes either.

I also plugged and unplugged every single connection in the car, but still the S. Old S.

I need help please! I mean it. Thanks.
