Turns over good will try to start one time and thats it. Changed fuel pump, fuel filter, crank sensor. Gets plenty of gas to fuel rail. Runs good and started fine before. Went to start it next day and just turns over.

Lets see what the actual fuel pressure is? Also if the security light is on? If the security light is on dont worry about the actual fuel pressure just yet.

Have you checked to see if the injector fuse is blown? Do you have power to one of the wires going to injectors with the key in the run position.

Have you ever heard of a injector noid light?You plug it into each fuel injector connector then crank the engine watching for it to flash. It wouldn't be a bad idea to scan the engine and body control module for codes as well.

We reset the security system. Turned the key to the on position let it sit for 10 minutes, turned it off and the van started right up. We let it run for about 5 minutes shut it off and tried to start it again but it wouldn't start. Did we do the security system right?

If it started from one 10 min cycle then it has nothing to do with learning the pass lock sensor. But sounds like you have a problem with the security system. Your going to need to have professional scan tool that can read the body control codes.I would need the exact code numbers not code descriptions? Might even need that scan tool to diagnose the problem by looking at live security data. You could have a bad pass lock sensor. That's most likely the problem.

I will have to look those codes up but those are engine codes and have nothing to do with the security system. If you did a 10 min relearn on the pass lock sensor and it started sounds like you have a issue with the security system. Did you just get a free code read from the auto parts store?Those and the do it yourself code readers cant read body control module codes. Thats where we need to find the codes they will start with the letter B followed by a four digit number. You might also need that scan tool to find the problem by reading live pass lock sensor data etc. They dont make it easy for the consumer to find the problem on newer cars. The professional also lol.
