Default RE: It cranks but doesn't start

I installed the new ICM but still same [:@]

What else could it be? Am I missing something here?

Is there any other fuses other than the side of the driver door?

I only checked 1st one. I dont think I have any spark on others because rpm does not even move at all nor I dont see anything blowing in the engine.

no exhaust sound or anything.

There are the main fuses next to the ecm that will cause this problem.

So you had fowled spark plugs but you didn't replace them? And you didn't have any misfire codes but everyone thought it was ICM? What else am I missing here?

Take the spark plugs out,pull the fuel pump fuse, release the fuel pressure,and turn the car over a few times. Let the plugs out for about a half hour while you go buy new spark plugs. When you get back put the new plugs in and replace the fuse for the fuel pump. Turn the Ignition key on for about 30 seconds and then try to crank it.

Let me know what happens.

LOL, no thats the O2 connectors, engine speed sensor connector, and knock sensor connector.
You have to open up the ecm box, if those fuses are ok replace the engine speed or crank sensor.

Ummm no. Both O2 sensor connectors, crank sensor, knock sensor, and maybe something for the abs depending on what year A4, but the brake wear harness goes directly to the clutster, its a simple circuit.
