New alternator had it tested before putting in new battery van still is dying and battery light is staying on. Im lost on what else could be wrong

I know I have a 1/2 tank of gas, but when I start the ignition the fuel gauge reads completely full. If I idle, the gauge will fall to completely empty & the low fuel warning will appear. The gauge will once again go to full if I shut off the engine and restart. No service lights appear when this happens (other than the low fuel light & bell tone). My engine has been running high RPMs at times and a new EGR valve has been placed. The engine temp will read high, but not into the red zone when it races.

changed valve cover gasket, putting it back together there is a hose that comes off the ribbed piece near top right of the engine where does the vacuum hose go?

tension pulley replaced already, all other bearing seem okay

Already replaced EGR, & EGR sensor, & evap pipes

I did a carmd and it showed me the areas to get check out the H02S-11 heater circuit malfunction (Bank 1 Sensor 1)

Even when I disconnect the battery a high pitched, fast, chirping noise comes from what sounds like the inside back of the van.

now the dash tells me security the car wont turn over or anything,if l bypass the starter and manually start it it will only run for about three seconds then shut down. [ have tried all the relearn proceadures with no luck. the light on top of the dash is not on or flashing any ideas at all would be greatly appreassiated
