Van will not start cold w/ delayed check eng light

Check the fuel pump relay. It will be under the hood in the fuze box or in a separate box of relays for lights aircon etc. It may be independently fuzed but the underside of the lid should help. If you don't feel it click on startup see if there is another the same for lights etc and temporarily swap them.
When you crank you, or helper, should be able to hear the pump running under the car near the gas tank. A high pitched whirring / buzzing noise.
If you have the knowledge to carry out this task carefully, then slightly release 1 of the fuel injector connections, have a rag ready and see if fuel is released on cranking. Use a connection as far away from the ignition leads / coils etc to reduce risk of fire. The pump could be putting out 40+ psi so take care!!
If there is pump noise and fuel emitted then the next thing is the cold start system which also has a relay, you should be able to feel both relays(pump and cold start) click with your finger on them when helper cranks up. The cold start system runs for a few seconds until the engine has established enough warmth to continue running.

Your ecu is in need of repair. Your jeep has what is known as the "delayed check engine light problem". Time has taken it's toll on some of your ecu's internal components, the ones that supply power the fuel and ignition circuit relays. The ecu is slow to supply power to the circuits in the morning, causing the delay. Your jeep may also have a bad crank sensor, which would cause the sudden shutdown while driving. Your ecu can be repaired or replaced, your choice. Both options are available on ebay.

The cold start switch might be bad, not allowing the cold start injector to fire when the vehicle is cold, causing a longer than usual cold cranking time.. Have that switch checked.
