I put in new headlights, and reinstalled my K&N Air filter, cleaned the throttle body, and now the Disco isn't turning over.

Battery is fine, drove it earlier today. It's in Park, I have locked and unlocked it.

Anyone have this happen to them? I am not thinking of what would not allow the car to start.

 

Several things come to my mind.
Any lights in dash when key is ON? Interior lights?
Clicking noises when trying to turn over?
Fully connected battery terminals?
After keyfob unlock, when you are sitting in the drivers seat is the alarm light still blinking? Make sure all doors and hood is closed, unlock button twice in a row.
Are you in park or neutral when trying to start?

 

Thank 04in719. I just got it going, I figured it was the alarm as you say. I must have immobilized the engine inadvertently. The alarm light should have been either flashing slowly or on constantly, but it wasn't. So I hit the lock button twice quickly, and then unlocked and she turned right over.

 

Sweet, glad to hear it.
It's happened to me too.

 

so, I got it started twice, am picking up mu son from daycare, and of course, not starting again. Tried the alarm button multiple ways. Not sure what to do except sit here and hope to get lucky.

Read and try the key sequence in the driver's door...
Good luck!

 

so, luckily I can keep the DII at Daycare in their driveway overnight. I will head back in the morning.

I will try the sequence, but any other things I should try? I will head backs with tools, multimeter.

I will check the starter connection. Anything else? Could it be a sensor near the brake pedal? Hear shifter?

 

I remember when this was one of my top concerns of the day...

 

Went back to get the rover today. Starts right up cold. Get home, turn it off, won't start back up.

I switched the starter relay, with the wiper fluid motor relay, still no start. I will have to inspect the starter.

 

Crank position sensor?
