I’m troubleshooting a no-crank issue on my 2010 Acura RDX and wanted to see if anyone has ideas. The engine won’t crank at all when I turn the key — it doesn’t even try to turn over.
Here’s everything I’ve checked so far:
• Battery voltage:
12.47 V with the car off
When attempting to start, voltage only drops to about 11.9–11.7 V
• Starter:
I removed the starter and took it to AutoZone for their bench test
It passed the starter test
Reinstalled it and the car still won’t crank
• Starter wiring:
The large battery cable is connected to the starter terminal (with the nut)
The small signal connector is also plugged in
• Starter signal test:
I unplugged the signal connector and tested it with a multimeter
Black probe on engine ground, red probe inside the connector
When someone turns the key to try and start the car I get about 11.8 V
• Fuses:
Checked all relevant fuses in the fuse box and they are good
• Neutral safety switch:
Tried starting the car in both Park and Neutral multiple times
Current symptoms:
When turning the key, nothing happens — no crank at all, dash lights and all other lights do come on like normal though.
Since the starter passed a bench test and the signal wire is getting ~12 V when the key is turned, I’m not sure what the next step should be.
If anyone has suggestions for what to test next, I’d really appreciate it.
