    1996 WRX STi (RHD/JDM IMPORT) NO START! FUEL RELAY? FUEL PUMP? 911-HELP!

    I have a 96 STi no start. JDM import car that landed in Canada in Feb. 107K km, timing belt changed at 96K. No mods. Was running fine when parked (2) days ago. Last pm no start.

    - Fuel pump not making any noise. Has 4.3V at the fuel pump plug. Hitting/tapping tank does not help.
    - Do not know where the fuel pump relay is located, JDM RHD.
    - Fuses under hood appear to be good.
    - Is there a fuse I should be looking at in panel on kick plate in car?
    - Should I pull the fuel pump and try jumping it? Can this be done with the pump in the car?

    Regards,

    temsinc

    Is the battery OK?

    Does it crank and not turn over, or just not crank at all?

    First thing to check is if it has fuel pressure at all.

    It turns over normally. Spark at the coil. 4.3.V at fuel pump. Shouldn't there be 12V at the fuel pump?

    At least on the OBDII cars, the pump receives variable voltage from the ECU depending on the pump duty cycle.

    UPDATE:

    I think I found the culprit. Pulled the fuel pump and jumped it direct to 12V to no avail. I think she gave up the ghost.
