Don't feel bad I am having the same trouble and am going to have to replace the fuel pump. I was a little more extensive in trouble shooting before I came to this conclusion. A lot of times it could be a wiring problem so you just have to foow the steps and trouble shoot until you find the problem. If your van is like mine Early 93 it is an OBD 1 System so it makes it harder to diagnose. If it was an OBD 2 it would be a lot easier. Here is atip for you. Go to Autozone.com and got to the fix it yourself secton. They have some pretty good and accurate trouble shooting pages. What I did was print out 3 diffeent possibilities ruled out most right away and it left me with 4 items to check . 3 checked out and the fuel pump did its thing so I checked fuel pressure at no start and it was ZERO. But I heard the pump pressure up but not enough to get through the regulater. So out comes the pump!
