2.7 trouble
 

Where do I start?
last year it started when it got cold out.
I have a 2003 allroad quattro 2.7
when outside temp was cold it wouldn't start or crank. if I worked the key it would start.
so here it is again getting cold weather.
the engine cranks strong, but won't start.
epc light is on so I changed the crank sensor.
still won't start.
I checked all fuses by drivers door.
I then checked fuse under hood. There's a 40 amp max fuse in with the ecm. It was popped.
so I replaced and still nothing.
also with car in on position and checked harness at crank sensor and didn't get 12v. On any of the 3 wires.
so now where do I go?
I would appreciate any info
thanks.
