Hi Scotty, I have an 2007 odyssey and I recently changed the battery and alternator. Yesterday, the battery was drained without leaving any electrical component on, so coudn't start the car but atleast the engine was cranking during start attempt. When I tried to start the car today, the engine doesn't even crank and the remote lock/unlock doesn't work either. Can spark plugs be the problem?

That's a parasitic drain like have an electrical short somewhere draining the battery make sure you tightened all connections on the alternator and battery
@noobmaster69 there is alot of reasons why an engine could be knocking but putting windshield wiper fluid in the engine oil filler is not good how did you make that mistake?
No to plugs, short somewhere may be issue, look at it dark, see if any interior lights are on, stuck, then move to electrical short, battery connectors, u may have to take to independent shop.
