Oh darn, another thread not solved
Did you tow the van to autozone to get a free scan for codes? of course you didn't. There's not enough information in the thread to tell what the problem was or if it was even a fuel delivery problem. You didn't say what kind of diagnostics you did on it. What made you decide to change the fuel filter? For an engine to run, it needs fuel, spark and compression and there could be many different problems causing any of those 3 from not happening.
