    My '99 V70 still won't start!
    I changed the 02 sensor, took it down from the jack, and problems.... cranks
    but won't start.

    There are no OBDII error codes, so I don't think I have a bad or a
    disconnected sensor.

    I am getting spark, and appear to have decent fuel pressure at the injector
    bar (checked the schraeder valve for fuel and pressure)

    I am at a loss for what to check. Does anyone have a list of connections
    (vacuum?) that may have gotten knocked loose, to cause no starting?

    Thanks,

    I would unplug the o2 sensor breifly and check the engine bay fuses for the
    injection system- there i a 10amp one in there as i recall. You may have
    somehow shorted the heater supply to the o2 sensor and blown the system
    power fuse- i.e. the same one as the heater which supplies +12v to all
    engine actuators like injectors, ISCV, etc etc...

    Otherwise...I dont know.
