Chrysler Repair: Stratus cranks but will not rollover, powertrain control module, crank sensor

Question
I have a 1997 Dodge Stratus 2.5L V6 that cranks like it's ready to start but just will not rollover. Seems to have no spark. Last week it started to make an odd noise and I took it to my friends work at Tate Dodge where they took a look at it and immediately identified that it was the Flex plate. Took it to my friends shop and had him replace it, sure enough had a small crack in the center of the flex plate. Once job was completed the car just did not want to start. They figured that it was the Crank Sensor so they went a head and replaced that as well. Still....will not Start. They are clueless and taking their sweet precious time getting my car back on the road soo im getting irritated and trying to come up with a possible reason why this is happening. Is their anything else they could have possibly messed up in there that could have caused this ? Battery is fully charged and both terminals are on nice and tight. Cranking very hard but theirs just no spark. Hooked up a tester and the PCM is responding but it is coming up with no DTC's. "All tests Passed". Worked perfectly fine when it went into the shop soo I don't think that it could be the distributor. Oddest thing tho, the Check Engine light is not appearing what so ever. Usually as soon as I put the key in the forward position the CE light would pop up and then go away as soon as the car is started. It just won't show up what so ever, no idea. Any ideas

Thanks,
Ken


Answer
Hi Ken,
I agree that the CE light should appear when you turn the key to the run position. It may just be burned out, or it could indicate a problem with the voltage supply to the powertrain control module which of course also runs the spark. But if they have a direct readout via a pluf in reader and get no codes or signs of "no communication" over the digital bus, then I would assume that is OK. Other than those issues, they might check the distributor cap and the rotor to see that either of those are not defective as that could kill the spark. They should be able to access that the pulsations to the distributor and the voltage supply to the coil are or are not present at the input plugs. So encourage them to separate the issue between the distributor itself and the powertrain communications to it. the distributor is expensive so I would be reluctant to authorize replacing it without proof it is faulty.
At least it is in the shop and not stuck at home!
