Hi,
I am a new member to the Subaru owners club and own a 2004 Impreza WRX STI (JDM). This is my first Subaru. I have owned the car for a couple of months and use it for daily driving. have already clocked in 7K miles in the 5 months that I have owned it. I was having a lot of fun with it, but when the weather started to get a bit chilly, the issues started to come up. Sorry for my naive post. I am not really a grease monkey or mechanically minded, but just try to solve most of my problems myself.
So here is the issue.
I started smelling fuel inside the cabin while the car warmed up, found out tightening up a bunch of fuel lines fixed it. recently, the power steering pump started leaking and I ordered a replacement. While I was checking the powersteering system for air bubbles, I noticed that there was fuel leaking onto the engine. on closer inspection, I found that the injector was being sprayed with fuel really heavily. I put a bunch of towels there to soak up the leak. Since I am now scared to start the car, I couldn't get a good view of where the leak was coming from. So I have attached a couple of photos down below indicating the area of the leak.
The leak seems to be coming from above the injectors and sprays a lot of fuel onto them. I can also see a massive amount of fuel getting sprayed sideways as well.
1. Could it be from the injector O rings, Fuel pressure regulator or one of the hoses?
2. Is there a way in which i could systematically diagnose the problem?
3. Could it be an easy fix or should I take it to a mechanic?
Any help is much appreciated
