sikwrx i think could be right checking the ignition switch.... altho i don't know how the alarm system is on the WRX's but im guessing that it cuts the system in at least one place? fuel? ignition? starter?

If you can hear the fuel pump prime it might not have actuated the cutoff on starter motor.

I'd check the barrel - but double check the alarm/immobilizer system.

Maybe off target but, my car just stopped going round a corner, no reason, just wouldnt start, pump primed, brant ok, most electrics, turned out to be an 8 buck fuse in the engine bay. Maybe there is a small crack? and heats up to a point of disconnection when the engine bay is idle, eg fuel stop. Brought my mighty Rex to its knees, now got a couple in the glove box.

Motor still under the bonnet?

OH FUK!! Thats it!! thanks man, I been trying to figure out wot was ment to go in that big gap for ages. U rock

Your problem definitely sounds like it is your alarm module relay or immobiliser module relay, faults in either of these systems produces the same problems you have described, sometimes it can be both modules- for some reason they can go at the same time. you will find the problem will get progressively worse to the point every trip up the shop results in a no start, but then will have no problems for a week. is a frustrating scenario. people often look to starter motors, batteries, alternator, but it wont be as you are getting power to all accessories, and its not even clicking over, which is a tell tale sign. All lights on dash will come on as if its immobilised but no click when keys turned. The relays go after a while and build up a high resistance. If its just one module youll be looking at a few hundred with labour, if its both modules ( id reccommend doing both at same time) about $450. They will probably upgrade your immobiliser to a newer version that has a few different characteristics to the one you have now, i personally preffered the original system. Anyway thats what my money is on, im sure subaru will tell you the same after a diagnosis. let me know how it goes for my own curiosity. good luck..

Im thinking the same
But I would read up on resoldering the conections inside the brant module
( see threads on rexnet ) before going to subaru
these bad soldered conections have been known to cause many problems like this and seems to be an easy fix...........

had something similar happen to me, i got to start her, fuel pump primes, then u crank the key and nothing, i pop the bonnet and then about 30 secs later the alarm sounds.

I wiggle the battery terminal clamps/leads and go to start her up and she starts.

Doesnt happen often.
