I'm really hoping someone can help me with an issue I am having with my WRX after a full engine rebuild.
So my car has been off the road for almost 2 years while I underwent a full engine rebuild. I finally got it all back together and went to fire her up and the car cranked, but did not start.
I had a local technician come check it out, and the first problem we noticed was that the fuel pump did not turn on when the ignition was in the on position. I had replaced the fuel pump to a DW unit and swapped it back with the oem one as well just to make sure it wasn't the fuel pump. They are charging me 100bucks/hour and after 10 hours of checking each pinout of the ECU they told me some of them were having wrong readings and that they want to swap out the entire dash harness which is gonna cost me thousands in labor. They think a rodent might've chewed through some wires while my car sat for 2 years, but I think it's kinda unlikely. I want to troubleshoot a bit further before I go with this option.
There's 2 things that I initially might think is an issue but the car is at the shop right now so I don't have access to the car but next time I visit I want to try out some things before I decide that the harness needs to be replaced.
First, I have installed new composite TGVs and in the installation notes it said the ground needs to be relocated. My technician told me this shouldn't be the issue since there are bolts that run through both the manifold and the blocks so it should still be grounded, but I had painted my manifold so it is most likely a grounding issue that I'm having. I was confused as to how to relocate the ground.
Do you run a wire from the ground on the manifold to the engine block, from the manifold to the chassis, or do you move the grounding point completely from the manifold to somewhere else? If someone has any idea on how to properly ground your car after a TGV delete it would be appreciated.
Second culprit is that my car was broken into while it was sitting and had my radio stolen. The thieves cut a bunch of wires to get the radio out but I don't really see anything in there that could be causing an issue. I will try to get a picture next time and make sure that the ground wire, which was one of the lines that was cut, isn't touching something.
I know my issue is kind of vague, I'll try to get a more clear idea of what the issues are the next time I'm down at the shop, but first and foremost I want to make sure my car is grounded properly with the composite TGVs in place if someone could give me some advice.
To clear up what I'm asking, there are 2 grounding points on the manifold. Shown in the pictures B and D. I am not sure if I need to run wires from those points to the block, or to a new point on the chassis. If anyone knows and could help me out it'd be seriously appreciated.
