I parked my car in the garage last night. Woke up this morning and my car wont start. It cranks over fine, just wont start. A while later i heard a noise that sounded kind of like an alarm coming from my car. I disconnected the battery but it is still making the noise? PLease help????????

 

Hey, you could have a few problems here.
Could have a fuel pump issue, or possible a crankshaft position
sensor thats faulty.

 

would the check engine light come on if it was a crank shaft sensor

 

the alarm got it's own battery and even if you disconnect it from the power, it will still go on.

have you tried another key? lock and unlock the door and start within 10 seconds.

it might be the anti-theft system dis-abling the engine from starting.
