Chrysler Repair: 97 plymouth voyager:no start, powertrain control module, 4 digit numbers

Question
my 97 voyager stalled on me while i was driving and would not start back up. the battery is fine and it sounds like it wants to turn over but wont. did not have any indicator lights come on before the stall.

Answer
Hi Dawn,
The best way to correct this stall and no start would be to get a fault code readout of the powertrain control module using a code reader that plugs into a socket under the dash next to the steering column. That would likely tell you what needs to be replaced. If you have a friend with a code reader that would be the inexpensive way to go. There is an outside chance that the ignition key might do the same thing, but officially '97 was not a year that still had that feature but give it a try. Turn in 'on-off-on-off-on and leave on' doing that in 5 seconds or less elapsed time. Then watch the check engine light, which remains 'on', to see if it begins to flash, pause, flash, etc. Count the number flashes before each pause. Then repeat to assure an accurate count. Write me back with the counts in order of appearance. If no flashing occurs, then a code reader will be necessary. If by chance it starts again and you can get it to an Autozone parts store they will often do the readout for free, or an independent shop will do it for about $40. The codes will be 4-digit numbers and let me know what those are.
I could guess and suggest a few things that would do this, but there is no point in throwing parts at it hoping that you hit the right one by chance. If you have a digital voltmeter I can tell you how to test a couple of sensors, one of which could fail in this manner.
If you write back, tell me which engine you have.
