Fuel filter/ and pump? Does your van have TBI ( throttle body injection) looks like a carb with 2 "sprayers" or SFI (sequencial fuel injection) has injectors at each cylinder?

[bighouse3867]

Yes on filter and pump
Sequential injection

Okay, thanks that helps. Have you changed the fuel pressure regulator? You should also check for vacum at the regulator. If I remember right the regulator should be on the fuel rail, where the fuel from the filter goes into the rail system.

that is next on my list.....I did change the vacuum line on the regulator....
another issue I have is that it will stall at highway speeds....I can put it in neutral and restart it, but it's a pain in the ass
