Well, it's been a interesting couple months with the Galant.
I don't drive the car much, but a few weeks back I started noticing the car was running funny as boost started coming on. I didn't think much of it at first, but soon realized the problem was getting worse. I loathe wrenching on the car these days, so some irrational part of me just hoped the problem would fix itself...But of course, that didn't happen. Since I rarely ever have issues with the car (it's been years at this point) I just think I got a little too spoiled.
So, into the garage I went to start troubleshooting.
I initially thought it was an ignition problem. I swapped out my COP for a OEM coil to no avail. On to my next suspicion, fuel.
After much dicking around, I found increasing the fuel pressure at the regulator made the car run better. My initial thought was my A1000, which are notorious for wearing out prematurely on E85 exclusive cars, was failing. Since I've been wanting to take my fuel system from way overkill to something more reasonable, I figured now was the time to make some changes. I decided to ditch my A1000 and dual 340 in-tank setup for a single Bosch 044 and Bosch Motorsport BR540 in tank fuel pump. Now, what I didn't realize is that finding a NOT f***ING KNOCKOFF
044 pump these days would be nearly impossible. So much so in fact, that I had to order my parts from EFI Hardware
in MoFuckiN AUSTRALIA.
Anyways, after some waiting for parts to get shipped around the entire world, I got the new pumps and did a quick clean install, ditching the Aeromotive stuff for all new German engineered Bosch greatness.
Annnnddd...Naturally, all my new parts didn't fix anything and I was left back at square 1 troubleshooting again LOL
By this point, I had also added a fuel pressure sensor that I could log with ECMlink. I used that to grab some logs, which didn't really lead me to any definitive conclusions. Fuel pressure (and the regulator) seemed to be working fine.
I went back to the fuel pressure regulator, and once again found increasing pressure made the car run better. At this point, I started to think my injectors were the culprit. In retrospect, this should have very obviously been my first check, but I digress. Can;t be great all the time I suppose.
I pulled the lines, fuel rail, injectors, and fuel filter, and confirmed some of my suspicions:
The filter was full of this mood dust sh*t. When wet, it was solid. As soon as it dried, it crumbled into nothing. At this point, I was convinced my injectors had ingested a metric shitload of mood dust, and needed a good cleaning. So, I sent them off the FIC, who confirmed that suspicion:
Once FIC sent me the flow sheet confirming the injectors were likely at fault, I started putting the pieces together:
1) The car sat while I was on deployment with E85 in the tank for nearly 8 months (f***up #1)
2) When I got back from deployment, I upgraded the fuel feed line with a 6an tank to rail, and swapped from a 10 micron paper element to a 40 micron stainless (f***up #2 and #3...you're not supposed to use paper elements with E85 and 40 microns doesn't filter out all the particulates).
3) The combination of stagnant fuel coupled with the 40 micron filter element let debris in the system pass into the injectors, clogging them up.
Somehow I couldn't put all thins together until this point in time.
So, got the injectors back from FIC and installed them in the car, crossing my fingers and hoping my issue would be fixed.
Additionally, I wised up and decided to run a dual filter setup to try and minimize and future occurrences of this happening. Probably overkill, but whatever. The 818 filters are cheap insurance. I decided to fabricate a Fuel Lab 818 dual fuel filter setup with a 40μ stainless element feeding into a 6μ fiberglass element (all E85 compatible this time...). The dual pass filters just before the rail should take care of any crap heading toward the injectors.
Put everything together, and used ECMlink to activate the pumps and check for leaks. With everything dry, I cranked the car up and went for a drive. SMOOTH AS BUTTER
. In fact, this thing hasn't ran this good since I had it out at Streets of Willow.
With the car finally fixed, I kinda fell in love with it again. I wonder if I'm ever going to be able to let it go, or if this thing is legitimately a forever car...
Lastly, I don't get everything right. I share with you all in hopes you don't f*** up the same stuff I do. Live and learn. But please, do learn 🤣
Thanks for following along
