"What I mean when I say " battery jumped but still nothing" is it didn't solve the situation. Obviously."
Don't be offended or say "obviously". It isn't obvious to anyone but you. WAY too many people say, "... And nothing". In the last year I can list dozens of totally different sets of symptoms that were all referred to as "nothing". I was told numerous times but I had to learn for myself, no matter well a test question is worded, if you have 100 students, you're going to see 100 ways it can be misinterpreted. That's why in all my replies, I'm very specific to avoid any confusion or misunderstandings.
As for diagnostic fault codes, those were erased when the battery was disconnected or run dead, so that information is lost. You will have caused another problem though, and that's why I asked if the engine will start and run if you hold the accelerator pedal down a little. Once the battery has been charged, (or jump-started), if the engine runs while holding the accelerator pedal down, the fix is to drive the van. The Engine Computer lost its memory when the battery was dead or disconnected. It has to relearn "minimum throttle" before it will know when it has to be in control of idle speed. Until that happens, you won't get the nice idle flare-up to 1500 rpm at start-up, it will tend to stall at stop signs, and it may not start, again, unless you're holding the accelerator pedal down 1/4".
To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the pedals.
