Chrysler Repair: 1993 concorde 3.5 will not start, coolant temp, sensor output

Question
I have a 1993 concorde 3.5. It will not start. It turns over fine. The fuel pump runs. It displays not codes. The battery is good and the alternator is working. I get a spark when it is turned over.  Not sure where to go.

Answer
Hi Ron,
Do you even get a 55 code? Is the check engine light working?
If you have spark that continues for a full 5 seconds of cranking, and you have fuel pump sound when you first turn the key to run, and you have gas in the tank, and you hear/measure the pulses of the injectors while cranking, then you have to have a mixture or a compression problem. I would check the compression and then verify that the coolant temp sensor is reading around 10-20k ohms across its terminals. The map sensor output voltage should show a decrease when you are cranking if it is working.  You might also want to clean out the throat and butterfly plate of the throttle body and its idle air side passageway. It would be very helpful to get a code via the check engine light so if that isn't illuminating I would replace that bulb.
Those are my suggestions.
