500 turns over No Start

[NorthGower]

Good morning .

Last weekend was out put on 100kms, next morning started up and drove to backyard.
Gave her a wash with garden hose, it started for 2 seconds then quite.
Went to start again and just turns over. Have spark sounds like fuel pump come on when turn key.

Any pointers where to go next.
