Chrysler Repair: My 1999 Chrysler Concord wont start, pulley bolt, chrysler concord

Question
My 3.2ltr Chrysler just stopped at a stop sign and will not start.  I went through the manual and do not have voltage at the injector coils above the spark plugs, I have voltage on one side of the relay feeding the coils but not the other, tried swapping the relay, no good.  Any ideas?  The book kind of shows the PCM controlling the relay?  Also hooked up a fault code reader, got no faults.  Basically I have no spark and cant figure out why?

Answer
Hi Thomas,
When you first turn the key to the run position do you hear the fuel pump run for a second or so (located in the fuel tank under the rear floor so it should be heard coming out from under the rear near the tires)? If not, then check fuse N (center of the front row) and fuse S (next to the last near the fender) in the box under the hood. If so, then the relay is OK because the PCM is programmed to do that for a moment. Then if you had signals from the cam and crank sensors while cranking it over then you would again get the fuel pump and sparking for as long as you were cranking it, but not when you stopped. Usually I would suspect that one of the two sensors is going bad in which case it would likely recover when it cooled down and allow the restart. But it will die again a little later. It could be that the failure is marginal enough to not set a code so you will need to test the sensor signal wires for pulsing voltage while you turn the engine over by hand using a socket on the crank pulley bolt. So let it cool down and then see if it will start and get you home.
The signal wires are black/light blue (ground) and for the cam sensor the signal wire is tan/yellow while for the crank sensor the signal wire is gray/black. The third wire of both sensors is orange and it should show 8V constant with the ignition switch in the run posotion. The signals should pulse between 5V and 0.3V several times per revolution of the crankshaft if the sensor is working. So you might want to test for this when it is in the failed mode (heated up but stalled out).
Let me know what you find out and we'll go from there.
