Could have a bad ground or a bad computer.

Take the computer out, and have it checked at a parts store. Most times their remanufactured electronics supplier can test them for a fee.

Engine control module???

Joe - Do you think the Engine control module could cause this? It worked fine last night and this morning it would not start.

Could very well be. You could also have a ground problem. Need a wiring diagram to start with that though. Check the links in my signature file for some wiring diagrams, but only the factory manual is going to have anything useful here.

We own a 90 Caravan and 2 things come to mind that have caused us a problem...The MAP sensor and the a Pickup which is located under the distributor.I think if either one is faulty it can tell the computer to shut off the power to the fuel pump and/or the plugs... One time we had it towed to a garage and all the tech. did was tap on the pickup and the damned thing started right up...go figure. Anyway good luck with your van and please post back and let us know what you find out.

There is a relay on this van called the ASD relay (Automatc Shut-Down) It disconnects power to both the ingnition and the fuel pump. They do go bad, and I would check that before I got into the more complicated things.
