Jamie,

One other thought is moisture in the fuel.  It doesn't take much for fuel issues to surface, and I've seen many chase problems that a treatment of Dry Gas solved.  Always a good, cheap, first treatment.  When I store my van for the winter, it is always stored with a full tank of gas, with a fuel additive like Dry Gas.

Once on a cross country trip, the van was running great... following a fill up at a major name brand gas station, it started giving me issues with the engine starting to cut off at highway speeds.  We coasted into a rest stop, slept on the issue, and in the morning it started right up. We drove for about 5 miles, with the problem resurfacing... pulled into a gas station, and purchased 2 bottles of Dry Gas.  Added one, topped off the tank, and drove the rest of the way home with no problems.  In fact, drove the rest of the summer without any issues.  Now I always keep a bottle in the van, as my 1st line of attack when fuel like issues surface.

Good luck with your van!

Subject: Fuel Pressure Regulator Bad?

Hello list,
I have been lurking for sometime and need your wisdom. I was having issues with my 1989 Blue Star before I parked it a year ago. It would run well but when it got warm I lose power like the fuel was cut off. I have decided to get it going again. I have tested the fuel pressure and read 36 psi with the vacuum line to the plenum disconnected. When I attach the vacuum to the regulator, the engine cuts off. Any ideas as what is happening? Thanks in advance.
