Project IRX: CRX-Insight Renaissance Experiment

[SVOboy]

Yay, I'd gladly take that plastic bit off your hands

[Christ]

Darius says: General Mail will take a few days to get to you, so you'll have to deal with a busted one until then.

This one is 21 years old, so it's gonna have tape on it when you get it, as the inner contact plate likes to pop loose from the plastic. It pops right back in, and stays there unless you really jar it.

[SVOboy]

Sounds good to me. Perhaps I'll have you send it up to dartmouth.

[Christ]

PM or txt address and I'll try to send it in the morning, or on Saturday when I leave for my Father's house.

Brace is exactly what I was talking about Right on!

Fazio's is a SoJo Institution. It is really that great. I could seriously spend a whole day there just looking...words just arent' enough to describe the inspiration that place can bring.

Now for some constructive critisism. The welds on the bottom of the brace are a bit globby. Practice some on some scraps with wide gaps. That should help get those smoother.

Thanks, they are pretty globby, eh? I haven't gotten the hang of how to start up from where I've stopped or there is a tack weld, since the flux makes it hard to get and arc going and then a huge blog ends up shooting out.

Anyway, I'm nearly done the rear mount, but the neighbors yelled at me for grinding so I had to give it up for the night, sadly. I'm pretty proud of what I've whipped up so far so eventually I'll show you where it's at now and then hopefully again when I finish.

I'm gonna get out for a snack break now, but first a question!

Spent the last hour and a half tracking down the issues with the ECM, it's not getting power. I've determined that if I run power right to the main ECM power pin (B1) it (and Will's loaned SGII) work properly, as well as the immo stuff. So, what's the problemo? Grounds? I think I've done all the multi-body grounds inside the car, but are there grounds hiding around the engine somewhere I need to tackle?

Thanks!

Does the wiring still have/use a main relay? (The thing that used to be in your left kick panel behind the dash) If it is, take it apart and re-solder all the points on it. If you need to, you can run the ECM on a switched lead instead of it's original wiring (I've had to do this before on the Civic.)

I wouldn't jump on grounds immediately for this one, instead, trace the wire from B1 back to wherever it terminates in the harness and every foot or so, check for voltage w/ the power on. At some point, you may find a short or open circuit.

The only ground that ever (normally) effects how the ECU operates is the one directly under the dash on the d-side, and the one that connects to the thermostat housing. I'm not sure what part of the harness you've reused, so you'd want to look into all the grounds (clean the contact point and the terminal with a wire brush) that you have used. Also, you may want to make sure the ECU is grounded (case) before you really get to playing with it, I've destroyed more than one by not having the case clipped to the body of the car.

Also, regardless of whatever engine grounds already exist, I'd still make sure there is one from the battery to the head, batt to block, batt to transaxle, batt to body.

Remember, the easier pathway you have for grounding, the less electrical load you have to deal with.

To clear up what confusion there may be on how I've dealt with the wiring, you should assume there is no CRX wiring left in the car, just CRX plugs on insight wiring. As such, the insight main relay, which works, is used.

I'll try to chase the wires, but it'll be annoying since it went immediately to a little junction box and now there are 4 wires running away from it. Time to track them down I guess.

Also, the battery is sitting on the floor in the passenger side of the vehicle, grounded to the body

So when you turn the key, you hear the relay click, then after a second or two, you hear it click again? (Or just the second click... some people can't hear the first one)

Yep, you'll have to either track those wires down, or run a wire from the output of the first solenoid in the main relay to the ECU directly. (The main relay is actually two relay solenoids.) It's probably better to spend 15 minutes tracking the wiring, though, so that you know exactly what the problem was, and you can fix it instead of trying to work around it, and having it happen again later on, possibly.

I've been trying to figure out the wiring. I thought it might be the fact that my fuel pump isn't hooked up since it's in the same wiring, so I fiddled with that for a while. In the end I figured out how I'm going to have to do my fuel pump wiring, but in using the battery to find the power wire for the pump I ended up spilling fuel all over the garage floor.

At that point I decided I should call it a night. I did manage to get the fuel gauge working though

Also, while I had the wiring rigged up I went ahead and pulled 4 codes from the SGII, will update with what they are soon.

Also also, I tried grounding out everything on ECM plug B directly to see if it was the issue but that didn't do it, so maybe it is the power. The two wires I haven't tracked for the power go out into the engine bay, but I really don't want to hack up that harness, since it's my last uncut one
