Flashing cel
 

Ok have a flashing cel, 05 wrx, can't pull a code I've tried about 5 different code readers. New oem coil packs and plugs all gapped right. 40 psi fuel pressure at idle, blip the throttle goes to about 50. Compression test all cylinders around 50-60 psi. Hasn't done a leak down, don't have things to do so. Brought car to a garage they charged me 160$ to tell me my car was misfiring, and that they couldn't pull a code. Great shop. So any other ideas?
