I believe it has been mentioned on here multiple time but I just picked up this van and it ran great until I changed the battery and washed down the engine a little. Now it start right up but stalls quickly. Have been trying multiple things but with no success..

Any ideas Chevy Fans?

That'll teach you to clean things up!
lol

Double check all your vacuum lines and make sure they're all connected.

I'd double and triple check the battery cables, too.

Battery cable have been checked as well as all vacuum lines, dried everything. Check coil, distributor and possible security issues. Seems to be a signal shutting off the engine / gas. Was in storage for a few years so I was just rincing off some dust etc. under the hood and then shut if off and have had this problem since. Low miles on this thing so with some new tires I thought I was ready to go!

Check/troubleshoot the fuel pump relay operation and connector, also the oil pressure sending unit wiring. The computer will bypass the the oil pressure signal for a few seconds on start-up but if it doesn't see a reading after that it will shut off the fuel pump relay.
Worth a shot, you may have gotten the connections wet/etc when you cleaned it.

I think he's onto something here!
The fuel pump will run for a few seconds when you first turn the key on to pressurize the system during cranking, but then it needs to see some oil pressure to come back on, that explains the easy start then quick shutdown.
I'd check the connections you can reach or see, especially the ones that got squirted with the hose, both visually & with a wiggle. Maybe take your leaf blower to it, if its moisture related it might dry out.

Tried all of this. Taking it to my mechanic to see if he can figure it out. Thanks for the feedback.
