Sounds like you have a sensor failure. There is a pressure switch at the
very back end of the engine at the very back end of the van right down
on bottom of the block just under the crankshaft pully. I had one of
these to fail. Just unscrew it, and install a new one. Not expensive,
but a PITA to get to, but you can get to it from up top. Don't have to
get under the van. The other switch is located between the push rod tubs
on the right side of the engine. It is a bit more problimatic to get to,
but can be done.

Hope this helps a bit.

Good Luck.
