2005 Chevy Cobalt won't start
 

My Cobalt won't start, won't even turn over.

There was water in the trunk for quite a while.

I've replaced the battery and the 50A fuse and the connectors and checked the ground in the trunk.

I've checked the fuses and relays in the engine fuse box.

When I turn the key I get no fuel pump sound and no crank.

I don't have a Key Lock symbol on the dash.

I've checked the ODB2 for codes but there were none.

Has anyone experienced this before? What would you try next?


Thanks,


A.
