Hey guys... new to the site... recently picked up a 2000 jimmy SLS 4 door... yesterday it started and immediatly shut off... scan it... said " VTD fuel disable " active as soon as it started... when it wasn't running... and key was in "on" position it was inactive... im just trying to find out exactly the problem before i throw parts at it... the only weird thing is the security light doesn't light up at all... even at first turn of the key... but it used to come on like it should as first key turn on initial startup and went off... up until yesterday it wouldnt start,,, i checked the wires at the passlock sensor on the column ...

Yellow wire - 5.22 V

Red/white striped wire - 56.2 mV

Orange/black striped wire - 8.10 V


these were with the key in "on" posistion... anyone have any thoughts?.... just want to know if these are the normal voltages for this... and that i just got a bad passlock ... thanks in advance!!
