If your EGI Comp 1 fuse is blowing, READ THIS

D
The purpose of this post is to assist owners having issues with the EGI COMP 1 fuse blowing.

My girlfriend took her 04 rx8 to a run down oil change shop and this overweight man(i kid you not, half the size of the car) took her car inside their workshop. After she got home, it wouldn't crank anymore.

We checked the oil and the "new" oil she got was the color of my poop after Taco Tuesday(dark brown). So we checked for some pinched wires or other signs of damage, but we were limited as to what we could see because we do not own a jack that would allow us to climb under the car.


Sooo as the boyfriend who fixes computers, she inevitably turned to me and asked for my help with fixing her car(because they are basically the same thing, right?) The most I have ever done to any car is change the brakes, so I basically learned what most things were under the hood and became really familiar with fuses and things to look out for.

So here were the list of theories I went through:

  • Replaced the fuel pump and it turns out that wasn't the issue. I chipped both of my thumb nails and cracked a bone in my left index finger. This was because I didn't use anything to loosen up that damn fuel pump ring...


  • Took out all the wiring for the amp that had been installed(lots of loose cables, could have been grounding or something along those lines). The trunk had so many loose wires, I thought surely that was the issue, but nah.


  • Looked for shorts in the wires around the engine bay. I did see frayed wire on the positive battery terminal connector but I wrapped it up with Etape and felt responsible.

So I looked up the issue with the google machine and couldn't find anything EXCEPT a thread on this website that was eerily exactly like our situation. https://www.rx8club.com/series-i-tro...1-fuse-167440/ [COLOR=Blue]He changed the fuel pump, checked shorts, took out amp wires...super creepy coincidence. He said it ended up being the rear 02 sensor causing the fuse to blow. It took him 3 YEARS TO FIGURE IT OUT.
-----------4 months later------------

-Lifted the car up and saw that the rear o2 sensor had been whacked. We pulled it out, cranked the car, and the EGI Comp 1 fuse didn't blow!

So we ended up replacing the battery(it would only hold a charge for 2 minutes) and we replaced the rear o2 sensor.

Moral of the Story: I discovered that I did not want to pursue a career in being a mechanic.

So basically what im trying to say is suck it.

At the end of the whole fiasco, the problems were:

-The catalytic converter on the bottom of the vehicle(lifted it up). It was busted.
-There was oil spraying onto the air intake, not allowing air to flow into the engine
-A few bad fuses
-Bad battery
-Bad battery connectors

I remember telling that dumbass ex of mine to not buy that car. What a **** show that was.
