I would like to, have not looked at the wiring yet. Maybe it will just work out of the box.

For a second I was going to type "yeah it would, just mount the pump" but than realize this was a fit.

I'm curious to know the amount of space that was added by building the tubular radiator support. how far did the radiator move from it's stock position?

Back in the saddle again. spent about the entirety of Sunday sorting out the test unit. Had to order a new crimper too.



This harness I got turns out to be in terrible shape, missing and broken connectors. Got another unit coming from one of the homies on facebook.



Wanted to test out the harness, but upon inspection it looks like the Fit has a returnless system. So I dragged the fuel pump out to investigate some solutions. Looks like there is a vent that will work great. Ordered a Grams 255lph and will convert it to a more traditional system.



Got some dope Sunchip dust incase you get the snackies



And sometimes you've gotta make a wonky tool to get stuff done.



Spent all of saturday working on this little project.

Dude you have some skills there. Most people on these boards would never tackle the rewiring themselves.

After the fab work done, the wiring doesn't even seem out of the norm haha. Good job, definitely coming along. I am so excited to see how this thing handles with that big wonky motor up front.

Hmm...that interesting. I didn't realize newer honda's don't come with a return system.

Took me off guard too, hope the plan to bypass that system.

Got that new pump installed. Grams 255 from the boys at Speedfactory.



Frankfuel setup now. Spring system is not functional but the intake is nice and low in the tank.



I was planning to try to start up the car tonight, unfortunately I cut the push lock fuel feed. So I had to put in an order for a bunch of AN stuff from Summit.

Got a few parts of the harness sorted out, DLC is now working and the motor is turning over.



The biggest problem was the "solution" to connect the car to the J computer. I cut the plug from Fit ECU and was planning on using that to build the patch harness. Turns out that the pins were making inconsistent connections, once I bypassed that connector 12v was flowing like sweet strawberry wine.





That's probably for the best. I have a little set of knock off Deutsch Connectors and will put on an 8 pin tomorrow.

Here is the setup for the fuel lines too.

Lots of research and even more hanging out with my old man as a kid, just building bikes and goofing off.

So this is how I spent the entire weekend.



Looking over diagrams trying to figure out why in the He-double-hockey-sticks
the fuel pump wouldn't fire. First problem was that the ECU didn't seem to be spitting out a +12v signal to fire the FPR. So I hunted for missing grounds, and blow fuses, and broken relays. LONG story short, A15 outputs a ground signal to fire the relay, once I figured that out the fuel pump still didn't fire. So once again I started pulling more fuses, and relays, and then spent about an hour looking for an inertia switch that was mentioned in the troubleshooting guide, a guide that was for a Civic, apparently, another thing that got overlooked in my mad dash to get this project busted out.

Another day of looking over the A plug for the Fit harness I noticed a sneaky little second relay that needs to be run to ground that should allow the pump to run, ground that lead and still nothing. Back to the diagnosing again, using the correct guide this time, do a few checks. Turns out at some point the lead from the ECU to the chassis got disconnected. Plug that back in and I hear that glorious fuel pumping sound.



Now the bay is a disaster from all the testing and wire swapping that happened, still haven't fired, but I think it should be pretty easy, maybe a missing ground or something silly like that.



Additionally here is the Fit A plug and its replacement.

Good stuff. It's great that you can track down and fix problems yourself. If a shop was doing it the price would be out of this world.
