Not familiar with the Impreza, but I'd say the most common cause of that symptom is the starter, particularly the starter solenoid. The relay is rarely a problem.

On the side of the starter solenoid there's a single small wire connector. This is where 12 V is applied when the key is turned to Start. This 12 V should cause the starter solenoid to pull the solenoid plunger which, in turn, connects the heavy cable coming from the battery positive post to the starter motor itself (below the solenoid). The pulled in plunger also moves the starter gear to engage with the engine flywheel.

Have you checked to see if there's 12 V at the single wire connector on the solenoid when the key is turned to Start (and, of course, the clutch is pressed down)?

I tried but it was too crowded on the engine side of the bulkhead.

No. Will do next time it fails to crank.

Thanks

 

What are the chances the starter interrupt is being set by the Keyless module and the repeated on/off eventually hits the 3 needed in the right time frame to reset the alarm and start the car?

Got the key fob/remote?

Certainly possible, but the probability of the security system locking the starting system out would normally be quite low.

The OP has another thread on this where you had suggested some tests, but there's no feedback. http://www.subaruoutback.org/forums...subaru-models/77874-2000-impreza-2-2-l-outback-sport-man-tranny.html#post799354

 

Yeah, I know. Texan wants him to knock his Subie around with a 2x4 like a roudy drunk at a Dallas bar.

I just throw em out there as I think of it. If its intermittent like posted here, I thought of the possibility that the alarm is activating. People have missed it before.
