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.
