Is your "Security" light on or flashing at all? This could be a VATS issue.
I've had this issue but not necessarily after a car wash - it turned out to be that I needed to replace my key as the pellets on the ignition key were so worn down (1993 Z28 with original ignition key) that it was not always sending the correct resistance to the VATS computer
- if the VATS computer does not receive the correct resistance from the key, the "Security" Light is supposed to light and shut down the fuel injectors and starter connection for a period of 3 minutes. After 3 minutes, the "Security" light should turn off and you can try it again.
If your "Security" light is flashing once per second, you got a short circuit in the system.
Here is a nice explanation of the VATS system and some diagnosis for this problem:
