Little update on (non) progress:
Finally were able to "listen" to injectors during a nonstart event. No injector clicking! This moves us to a different area ... The PCM, sensors, harnesses, etc, etc.
Since we could not find any easy means to thoroughly test sensors, we thought we would just throw some more money at the problem. Beware!, after much wasted time and effort, we have detemined that the cam and crank sensors for this vehicle are cataloged wrongly at AutoZone ... will not hook properly to the harness, with pigtail lengths as provided. However, found AdvanceAuto (a longer drive) to have exact replacements ... and lower cost!
Hopefully these sensors get installed today. (It looks as though the crank sensor has been upgraded ... now has a metal sleeve over the sensor probe ... for heat perhaps?)
Stay tuned .... |
