this is a 96 Chevy astro van >>>>>>> it starts fine but in about 1-3 seconds running it stumbles and shuts down, now please note! everything has been changed like the wires-plugs-cap-rotor-fuel filter and even the ignition coil and it's still doing the same thing the fuel press it's 62-65 psi steady even when it's shutting down the fuel press won't change ,,, so if you happen to know about this problem please help ,, thanks a lot
also note! this van drives fine it only does that at starting time ,,thank you
 
Sounds more like compresion problem, getting too much air into the engine.

If you start the engine and have no load on it (putting gear into nutural), does it last? or last longer?


Or a spark plug that aint fireing right, make sure they all seated properly
