No 12VDC to acc fuse, and engine won't crank

[Kevfra]

Installed a AVIC D3, operated it fine before mounting after I'd done all the wiring, and had to leave town for a few days so I left it sitting still hooked up but not installed. Came home - doen't play and car won't start. Panel lights up but no crank at all. Battery is fine. ACC fuse blown. Replaced but still no crank, and no power to acc socket either. Using a DMM I find no 12VDC at the acc socket with the fuse removed. Like something big popped and even though it blew the fuse it took out something else? Would this stop the car from cranking? Seems more like some immobilizer feature, like maybe my key programming got erased or something. Even changed the ignition switch but no change in problem. Help?

I don't know about the ACC being dead, but twice now I've been in the situation where my dash would light up (and headlights, and the roof worked fine) but the engine wouldn't crank.

It turns out that my huge size-13 boots keep catching one of the wires to the clutch interlock switch. If the wire becomes disconnected, the car will think you're not pushing the clutch and hence won't turn over. (I'm assuming you have a manual transmission.) It's a little brown wire, easily accessible under the dash. Just follow the clutch pedal up and you'll see it. Let me know if you need a photo.

Cheers!

You may want to check the following fuses related to

-Central locking/alarm system control unit, engine electronics control unit

-or Terminal 86s: Instrument cluster, radio, central locking/alarm system control unit, info system, roll-over-sensor control unit

When I first bought my car, the previous owner had the XM power spliced from the factory radio. Since I didn't subscribed to XM, I decided to add some accent lightings to the footwell area drawing from the same power source. What happen was I heard a pop and same thing happened to my car. You get the gauges lit up but the car doesn't turn over. So I checked every single related fuse I could find, and eventually the culprit had to do with some radio alarm fuse that blew. So check thoses fuses above and look at your fuse box diagram to see if there are any other possible fuse that are related to alarm or radio and check them too. I pulled 4 fuses out before I found the one that was broken. Needless to say, I removed the XM and the accent lightings and removed the spliced wire to insure I didn't draw any additional power from there again. No problems ever since. Good luck.
