Chrysler Repair/'97 Concorde 3.5L will not start.


Roland, sorry I messed up on the normal reply. I checked for spark and basically have none. I checked all 6 spark plugs and I have 1 spark on cylinders 2 and 5, then it stops. No spark on any of the other 4 cylinders.  Could it be the coil pack being a problem or does the PCM see that it is out of time (from my water pump replacement) and shuts the spark off after the first spark? (I did have voltage at the wire at the coil pack while cranking)

Hi Ken,
That is a bit contradictory because usually if there is a loss of crank/cam signal that causes the dark green/orange wire (and the fuel pump too) to be cut off as a fire safety precaution.
So I would encourage you to check out the timing mark issue as it may be there are signals enough to keep the pcm from shutting off the voltage to the coil but not good enough to produce a reliable spark at all the spark plugs when needed. I will await your results, and keep checking for fault codes.
