OMG
When the truck is in this state all sensors are at a baseline reading
It helps give an idea of sensor electronics Integrity unplugging the ICP Checks this as we'll in a round about way
getting a reading at KOEO IS easier Plus it checks the wire harness integrity for this sensor as well
Most early HPOP do make it to the 100k point but not all
Early HPOP are poor design
Starting it in 32*f or below without the block heater plugged in helping get the oil warm is very. Hard on the pump I'm not saying that's what you did just saying there's other variables that play in HPOP LONGEVITY[/QUOTE]
looks like the problem so far today is passenger side injector O-rings bad I'm going to replace those And hope for the best
