Chrysler Repair: Chrysler Repair - 1996 Dodge Caravan 3.0L will turnover but not start - CONTINUATION, dodge caravan, spark plug wire


Question
You had a previous question and answer thread regarding a 1996 dodge caravan which would not start.  This string of questions ended with the following questions which were not answered:

'Alright, so is there or isn't there a  sound of the fuel pump humming for about a second when you first turn the key to the "run" position, before trying the starter (there is supposed to be such a short hum sound)? And there is no spark when you are cranking it?
Please verify both those or tell me otherwise. If you have no spark AND no fuel pump when you are cranking it, then that would be consistent with a faulty senosor(s)'

THE ANSWER TO THIS PREVIOUS QUESTION MAY HELP US!

I have the same problem with a 1995 dodge caravan which will not start.  When trying to start, the engine turns over and the fuel pump can be heard (while laying underneath the van).  If a spark plug wire is removed, no arcing/sparking can be observed.  A new coil was tried with no change in the result.  I have applied a volt meter to the two wires leading to the coil and nothing could be measured when the engine was turned over.

This all happened after driving through a mud puddle and the van stalled.  Since then we have been able to re-start it.

I am assuming we have a short circuit but I am unsure where to look. =(

Hi Richard,
Have you tried for fault codes using the igntion key? "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 begin to flash, pause, flash, etc. Cound the number of flashes before each pause. Then repeat to assure an accurate set of flash counts. Then group the counts in pairs in the order of appearance to form the two digit fault code numbers. The last such number is always 55 because that is the code for 'end of readout'. Then write back with the results, or go to www.allpar.com/fix/codes.html for a code translation. I believe that will be the best way to begin.
Also check fuse #3 (eng) in the power distribution box under the hood. Then while cranking measure the voltage compared to ground on the dark green/orange wire (the cross-piece of the T plug contact arrangement) at the spark coil, during a 5 second crank. Do you get 12V for the full 5 seconds?
