1997 Chrysler Town and Country anti theft system

I am experiencing an intermittent problem with the anti theft system shutting down the fuel pump and not allowing the van to start. I used to think that it was caused by the system not resetting when the doors were unlocked, but it has done this even when the doors were not locked prior to starting. I had it towed to the local dealership once after it happened, and they told me it was caused by a loss of communication between 2 of the ecm's. They then "reestablished" communications between them (for a cost of $125) and it worked for a while. Twice I have had the van towed to my house where within 4 hours it would start again. I know it will not start the moment I turn on the ignition and the display for the odometer and the gear shift indicator are not lit up. Can you help me? I have not driven the van for over 5 months because the dealership doesn't have a clue what is causing it and they want to start changing out the control modules which they say cost around $1000 each. I would gladly donate to your cause if you can help me. I am not in a very good situation financially right now and do not want to offend you by making too small of an offer. If you coud help me solve my problem, what would be a proper donation?
