I'm posting this for a friend who has an older model impreza (mid-90's). We're having an issue where the car is throwing a CE light, giving the reason as a problem with the fuel pump relay system. The car semi-stalls intermittently while driving, in any gear, at any speed above idle. The car dosent stall completely, though -- the tach drops to zero and quickly jumps back up again.
Would it be a bad idea to hard-wire the relays (so that the circuits they control are always "on") just to see if that is the problem? Any other ideas on what it could be? I think he has replaced the relays once already.
Any suggestions appreciated. Thanks...
