It runs great some times won't start let it sit little while or sometimes a day and it will fire right up. The garage had it for a few months and i t neaver happened it dont show no codes it dont give no warning. Security light comes on and stays on when it happens and gas hand goes crazy. And u can here the fuel pump. Have resit the computer and everything. Dont no what to do its to good of a van to get ride of if I can't fix it I'll put a new moter in it

 

May be a Passlock issue. May be a short somewhere in the wiring.

 

I have a 2000 same van. There is a black box right under dash, a security box. When it won't start unplug it for a few minutes and it will start. Mine does anyways.Everytime my security light comes on i do this. I can't hear my fuel pump most of the time when this happens. It's a 4by 4 black box about even with my right knee.Keep the key on so you can see security light go off when you unplug . I also push my van back and forth in case something is making my fuel pump stick.Good luck and i hope this helps you.
