P2066 relates to a fuel sensor level:

P0404 relates to an EGR fault (Exhaust gas Recycler). You may be able to clean the EGR:

Whether this is causing your battery to drain isn't clear - there are other causes of batteries discharging, such as burnt out diodes in the alternator.

Treat it as 3 faults - try and rectify the 2 error codes first (disconnect the car battery whe not in use to prevent it draining) .. and then look at the cause of the battery discharge

sounds like worn rubber parts. Shoot some liquid lube on all the rubber parts focusing on where the rubber meets the steel part.

check for failing drive belts and check for a pulley that is running hot or reluctant to spin freely

the passerger side fron has an axel shaft that comes from the transmission and bolts to the engine block and the axel shaft has a bearing in it (its probaly called the inner axel shaft) the outer shaft goes from there to the wheel, the inner shaft is solid, the outer has rubber boots on them.

If the pump is starting to seize up, the belt maybe slipping on the pump pulley, causing the burnt rubber smell.

make sure auto shutdown relay isnt burnt out..also have it checked for a bad crank/cam sensor

You may have a frozen bearing on the tensioner or belt idler. This will cause the belt to burn and smell. I think you are on the right track. I would remove the belt and spin the idler and adjuster by hand to see that they are free and don't have excessive play in them. Replace as necessary.

Yes, get that oil changed ASAP, but the rubber is probably one of the two "doughnut" rubber rings that tie the exhaust system up on hangers.
