Chrysler Repair: 1999 Grand Caravan V6 3.3 L: no start, 4 digit numbers, grand caravan

Question
I recently bought this van from a friend and after driving it for a couple days it started to have problems with it not starting. at first it was speratic and just getting a clicking noise when we tried to start it. I replaced the starter, starter relay under the hood, and the battery. nothing has worked so far. checked all the connections and cleaned all the connections. Nothing has worked. When it does turn over it will not start. It just keeps cranking over not ignition. this is a problem that did not occur before i replaced the starter. Any Ideas?

Answer
Hi Michael,
Try to get fault codes using the ignition key: "on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the odometer window to see the mileage change to showing any 4-digit numbers preceded by a P. Let me know the numbers and we'll go from there.
