Hi guys, I have a healthy 1999 Impreza EJ22 with about 180,000 miles running in my 1987 GL with a good aftermarket fuel pump. It's pumping a consistent 38 to 45 psi. My questions is: When the vac line to the fuel regulator on the fuel rails is disconnected, is it still supposed to flow fuel back to the tank? I have a steady stream and pressure with it connected. When I disconnect it, the stream reduces very slightly but is still strong and the pressure rises a few psi. I'm trying to diagnose if it's not regulating properly - also temperature dependent... I'm having stalling issues when the car is hot and it doesn't throw any codes. Thanks, SK -
Hey Guys,, I haven't had the chance to research this, but it seems interesting. It says this unit has it's own built in ECU and can control ignition timing.. Only 8 connections. Could this be a viable replacement to a carbed unit without having to find a GEN3 donor SPFI and wiring harness.. What are your thoughts.. this seemed interesting. http://www.atomicefi.com/home.aspx I looked into the pricing... 2 GRAND!!!! Probably not an option for any of us.. but, still, interesting!!!

So i recently bought an 87 subi wagon, it had intermittent spaz sessions where it would lurch from low rpm to high. it happened under load most. I think tracked it down to the FI system, most likely electrical... i thought i fixed it with a new rotor and cap as it ran well for about a mile... when it completely stopped getting fuel. My fuel pump is fine. but I tested the FI itself and it its impedance is out of spec. I'm not sure if that can cause it to fail to inject fuel or not, but currently my next move is to get a pick and pull fuel injector that passes the ohms spec from the book. ive got all the pieces of the puzzle except fuel to get her started again. Any of you guys think that the spaz sessions, and the not starting is the same issue? Is there anything i haven't thought of that could be causing this issue? If so which systems would be good to check? Thanks in advance.
