Holy cow! Make sure you stick to the basics here. Battery cable corrosion, Ground straps to the body. Bolts tight on the alternator. I have seen all of those issues and they can all cause that problem. Also, I have seen a voltage regulator (internal one) swing up and down on voltage when certain RPM is met. Please stick to the simple items.

This may help.

Sound like your fob and your pcm are not communicating with each other.try the other key see what happens.

Have your electrical system tested for shorts.

You starter could also be using higher amperage if its older. You would need to remove it and have it checked at a parts store.

You can buy a switch that mounts on the battery and disconnects the battery completely from the vehicle when not in use. This way you can rule out a short AND have a practical way of immobilizing the van when you want to.

cam sensor is located in distributor

In the 87 model the check EGR light was triggered by mileage to get you to have the EGR cleaned and serviced. In 87 they didn't have differential pressure transducers or smart computers to monitor EGR performance. On the right Side of the dash there is a square hole plug about 1 X 1.5 inches square it's behind your key ring if the keys are in the truck looks like it's for a factory option switch that you don't have it matches the one on the left side for the emergency flasher switch. Pull it out and look in the back of the hole at the top there is a black switch I can't remember if it resets the EGR Light or just checks the light Play with it and see of it turns off your EGR light.

1. Check the Motors, or similar manual at your public library for your van or enter your problem in your internet search engine.

does it try to turn over if not it could be that the battery is dead if that not it then you mit have a blown fuse

Have you actually tested voltage output with multimeter, as this all happens ? May need new alternator to start with, it has voltage regulator built in I believe.
