Alarm goes off with ignition on. Dash lights work so there is power but nothing at the starter motor

SOURCE: have power but when i turn key i get nothing. no click,no starter???

I had a similiar problem, I had a bad sensor at the back of the engine, it was connected by 2 hoses to the EGR pick up tube.
I unplugged the sensor and the car started, I drove it to the parts store and replaced the part and it ran great after.

SOURCE: turn the ignition on my 330d fuel pump buzzing ok

test power to starter with a voltmeter while someone else turns the key. if you are getting power, than solenoid is faulty. If you are not getting power, than relay or ignition switch is bad. Do double check your battery connections to make sure they are metal to metal contact.

SOURCE: Ignition switch failed and starter motor stuck

Hi, Look for a fuseable link not just going to the starter, but also coming from the firewall where the ignition wires come though. Hope this Helps, RSMITH972278 P.S. PLEASE RATE MY ASSISTANCE

SOURCE: ignition on but starter won't engage. Had new key

sounds like you need to relace the starter

SOURCE: I bought a Chevy Trailblazer, used, had keyless

You need to find the black push button called the valet button. That is the overide. Get in the car turn the key to IGN as the alarm is going off and then you have either 5 or 10 seconds to push that button once and then 2-5 seconds later the alarm is shut off. To put the car into valet mode which means no alarm at all you put the key to IGN push that button once then pull key out at which point the blue light should turn solid blue.

Or option two is you open a door and hit the lock, then unlock, then lock button again on the remote and the blue led will be solid which means no crazy alarm.
