Pretty good. Fired up the samara the other day from hibernation other than the starter bendix is going bad it fired right up. Purrs like a asthmatic kitten. Back to work though have a good one and good luck with the fuel pump NS.

So I checked the power to the fuel pump and it was 12.4 volts and then I checked the power to the fuses and it was a big goose egg. So from that it seems the fuses aren't getting power.

Actually what happened was I first started to check the fuses and then the plug to the pump and kept getting zeros, I was pretty sure I was doing it wrong especially when it showed no power to the ignition. I then realized I didn't actually have the black wire on something grounded. I then followed that with checking the the side of the plug to the fuel pump after i disconnected it that wasn't connected to power when disconnected. Embarassed Eventually I figured it out and got the above results.

The other part I'm confused about is that the battery light, oil light, and parking break light (which is engaged) are all on when I connect the batter but don't turn the key, actually no key in the ignition and all of those are on. I imagine that should all be off until I turn the key to accessories, no?

Yes they should be off. Maybe double-check your connections on the ignition switch.

Hold on. You can't have power at the fuel pump and nothing at the injection system fuses. The fuel pump is powered via a relay from fuse 1 (Red position - the other end from the blank position) on the ECU fuse panel.

You probably have power to the fuel level sender which is independent of the injection system.

There is a 50amp in-line fuse hidden behind the footwell A-Panel near the ECU/ECU Fuse panel/Diagnostic socket. Remove the plastic trim and it's in there somewhere, this is the main feed to the ECU system. Check this isn't blown and whether you've got 12V or not. If there's no power here this is the easiest wire to trace back to the ignition relay to (a) find it and (b) check it's energising. You can also temporarily "inject" 12V at the main power fuse to see if the ECU and associated gubbins want to play.

Hey GB, so I checked the fuse and it has power 12.4 V, I also double checked the other ones and still no power.

I don't know how to "inject" 12V into the main fuse.

But I've also add some pics below.

In terms of my instrument panel these are the lights showing once the battery is connected, this is even without the key turned to the ignition (not sure if its like that with ignition completely disconnected I'll have to check that)

These are the wires to my ignition, in this configuration when I turn the key the check engine light comes on, also I did hear something electrical starting in the engine:

And this is the fuses I checked, red one the 50 and the three blue ones are 15.

Again I really appreciate the help.

Hey I saw that picture on your site GB but my ignition is different... regardless I attempted to follow that as closely as I could and sadly it resulted in no power to the ignition, and the lights still on. I've put a picture of what I did and you can see there are two extra prongs and two wires that come out of the bottom of the ignition. The two wires I have connected to the same ones that I disconnected from it before, but I'm guessing the blue / black wire isn't where I want it.

I'll have to look at it again tonight as I could only take a quick look at it before work...

Follow the terminal numbers not the positions.

I'm becoming more and more suspicious of your new wiring loom.

Coincidentally my excitement from putting in the new loom is also turning to suspicion.......

Re: "injecting power"

Take a wire directly from the +ve battery to the ECU side of the 50 amp fuse. I suspect it'll start if you do that temporarily.

I've had a look at the wiring diagram for the carb version of your car and the colours match your loom.

Your ignition switch should be:

50 Red/Blue
30/1 Brown
30 Red (Brown tail - your's has faded to pink - the little short wire)
15 Blue

Note: There is no Blue/Black on the ignition switch!

Disconnect the battery +ve while you change the wiring and just touch the terminal back on to make sure there's going to be no blue smoke.

So I set up the wires as you said and the battery oil and parking brake lights stilll come on. But when I turn the key to the accessories but not all the way to turn it on the check engine comes on and the tail lights turn on so something is working right there, I think.

Also I hear something powering up in the engine area. Still no fuel pump but its something.


As a note I do have a blue and black wire that is with the ignition wires so I dont know what to do with it... Ill have to double check but I think they may have been put together on the old loom. [/u]

Greetings all,

So I'm beginning to give up on my rewiring project as it seems the wiring I need for my Niva is not the wiring have or can get. That being said: how complicated and what is the process to swap this engine out for a carbureted one or even a fuel injected that's not GM influenced (as I believe this is part of the problem).

Any help is appreciated.
