Very hard start drove great next day wouldnt start bought battery did not start held key on for a bit started making a noise i cant describe had a smell i cant describe finally after struggling turned over drove 45 miles came back car wont start one click i can hear under hood. Help?

 

Checked oil, checked battery voltage, checked coolant temp and level under pressure cap, pull valve cover off and inspect timing chain?

 

Tighten the 4 bolts in the fuse box?
push all fuses and relays firmly into their place?

 

You don't like to punctuate?
