2006 Altima wont start
I had it sitting during deployment, replaced battery, fuel
pump, and camshaft position sensor, tested it, it ran. So i
drove it to my new residence, after which it wouldnt turn
on anymore. Battery was bad, so im thinking the
alternator is too. Battery was under warranty, so i got a
new one. Replaced the crankshaft position sensor and it
turned on again. But my dumb friend turned my car off in
the parking lot of Autozone to get the codes checked..
now they cant read my codes and i cant turn it on
anymore. Furthermore, when the key is turned to ON,
there is a continuous beeping coming from behind/below
the engine block.. Help?
