Parked the Voyager overnight at house. Next day engine cranks , no start. Getting no fire, not reading any code to display. Replaced most electronic parts including PCM. Did not replace crank sensor yet. Getting no codes for a sensor prob. Have had far and few episodes of it trying to stall at red lights. Like I said, not showing any codes. 3 pin connection at coil showing center tang is hot .What you think

becaue the pcm was replaced it may not start unless a mechanic programmed the security system. put old one back in if you have it and reset security system it will probably start. if not have towed to mechanic so he can program security system now that is has a new pcm.

The PCM was replaced 2 yrs ago. Never had any issues with it ti my knowledge. I have been informed the crank sensor can go out and no code can show. I mean, have had some hard starting in the mornings. After it starts it ran fine. Have noticed though a little decrease in power though. Fuel system well within specs, has good compression. No spark from the new coil I just installed.

the crank sensor can do that but security reset it pretty easy so try that first then , also do wiggle teston crank sensor harness as they go bad on Chrysler products too.

Yes, this van does not have a security system on it. Going to disconnect the neg. and put a new crank sensor on. Going to check out the harness on the CS also. If it's not that, would be moving towards the PCM. Will get back with ya. Thanks for the reply, AC

Just to add to this one you can measure the resistance of the crank sensor usually when they fail they will read no resistance as a open circuit.
