Here I am reading this post for the 1st time, 13 years after it was posted. In fact, it's my first day on this website. At least one of you said you didn't have test equipment yet said you had good fuel pressure. How did you know you had good fuel pressure? With carburetors, only a few PSI fuel pressure is needed and it's the vacuum that draws the fuel mixture into the combustion chamber. Fuel injection is different. With the vehicle you have, you should have between 30 and 45 PSI of fuel pressure. You need about 20PSI or so just to start the engine. When it drops down to about 20PSI it will stall. I'm working on such a van right now that has the same problem. The fuel filter was replaced by someone else and it didn't solve the problem. I'm using a pressure tester and determined that the fuel pressure regulator is good. I have dual tanks and it does exact same thing no matter which tank is switched on. I believe the problem is with one of the fuel pumps, but I don't know which one it would be and don't know how to confirm a faulty pump before spending money on a new one. I've spent hours on this forum today and I see the problem is common, though not always exactly the same. I noticed that on almost every thread, no solution to the problem is ever given. It sure would be great to find a forum where problems are solved and the solutions are posted. People take help from others and when they solve the problem they don't bother to give a follow up.
