Ran into some deep water tuesday, now jewp wont stay on...
It ran fine the rest of day, drive 45 min home . That was Tuesday: went to start today , she fired right up but sputtered off when gas pedal applied. My thoughts are fuel pump or computer. But would wound water burn out the pump? The rear wasn't even really that deep. Any thoughts are great before I just start replacing things. Thanks

Nice photo - suitable for framing.
If you have Federal Emissions O2S's (two O2S's) or California Emissions O2S's (four O2S's) the front (upstream), and/or rear (downstream) O2S ('s) may have been submerged. A bad upstream O2S will give you stumbling (sputtering) problems. Detach the O2S connectors and squirt the connectors down with Electronics cleaner and see if this helps.
