Good reply. I'll give it a good look later and try and help. Looks more promising now though I reckon.

 

2-row and 3-row is a simple way of identifying the ECU families (basically old to new), where we're referring to the number of horizontal rows of pins on the ECU plug.

 

Yours is a * *** *** 119 which is a 2-row, so you have an older (original Mi16 alloy block) ECU, which does not run knock sensor or lambda.

 

We'll get there, but you should start matching connectors to what they fit, eg AFM, TPS, coil etc. Only one plug on the loom will fit each of these items.

 

See how you get on. Your solenoid/starter wire will be a thick, pale blue wire most likely with a female spade connector on. It fixes to the male spade on the solenoid piggy-backed to the starter motor.

 

The attached document may help you out a little bit if you study it.

 

Good to know that its a 2 row. GLP's diagram will also be useful aswell know. Everything apart from the fuel pump is plugged in so hopefully if can get some power on it i'll see whats going on.

 

cheers for the help Sarty, really appreciate it.

Your FP plugs in like this:

 

The FP relay is in the Mi loom. (The other relay is for the injectors).

 

From the FP relay will be a wire in the loom going back inside the cabin, which SHOULD end in one of the 2 brown multi-plugs which connect to the matching brown multi-plugs (1 x 6pin and 1 x 9pin) under the steering column. It SHOULD go to pin#2 on the 6pin brown plug.

 

To be sure you have the correct FP wire, you can check it to the FP relay (and you'll know it's the FP relay because the injector relay will have wire feeds to the injectors themselves - so you should be using a continuity tester for this) and then hopefully to pin#2 on the 6pin brown plug.

 

The matching wire on the other side of the 6pin plug should be a thick white wire #76. There is a fuse in the fuse box which feeds the FP, so if it doesn't work check the fuse, which I think is #15 (and 15A BTW).

 

There are some earthing rings you need to connect: one is by the injectors and earths where the fuel rail affixes, and a larger green and yellow wire which can be earthed under the ignition amp mounting plate.

 

And the loom needs power too of course, but I don't recall if it comes from the brown multi-plugs or from a connector to the shunt (power distribution) box just off the battery live terminal.

 

Keep going dude.

I don't have a earth at the fuel rail, only the the gearbox stud and at the ign amp.

Not saying it's necessary matey, just that there's one on an OE loom.

That earth is only present on BX 16v looms, 405 Mi16 looms don't have them.

[GLPoomobile 958]

I thought that was probably the case. Both the original loom on my car and the spare I used for reference were 405 looms.

hello, sorry its taken me so long to do this but pants rain and wind and darkness didnt make it easy last week. on saturday i managed to have a look over the car and take some pictures. I was sort of told that the guys trying to fix my car before had said that the ecu and chassis where different potentials and that some 205s where like this? hmm. well i managed to find that the GND chassis cable hasnt ever been connected to the battery, so im thinking this might change things alot?

 

anyway heres the pics:

 

Pic 1 shows the ECU and 3 wires. A thick YE one, a GY one and a GN one.

 

 

Pic 2 shows the 6 pin and 9 pin BN plugs?

 

 

Pic 3 shows a BN 5 pin plug that has a YE wire with socket on the end and a GY wire that turns to YE and goes to the fuse box.

 

 

Pic 4 shows where the GY wire goes on the fusebox. i havent got my haynes manual to find out what this is on the fusebox.

 

 

Pic 5 Shows what i beleive to be the FP wire from the fusebox?

 

 

Pic 6 Shows a WH 5 Pin connector with a YE wire with a socket and a GN wire that turns into a GY wire that also goes to a socket.

 

 

Pic 7 shows that im thinking that YE wire from the ECU goes to the Large WH 76 wire in the 5 Pin BN connector and then to the YE wire from the Fusebox to the FP? But im not sure where the GY wire is supposed to connect to at the ECU end (its very long).

 

 

Im hoping to get the Chassis GND connected asap so i can plug the battery in and see what i get. I'll go from there.

 

Any help would be greatly appreciated.

I'm not entirely sure what you're asking here, as you're saying what the picture shows and there's the odd question mark here and there.

 

You've certainly inherited a mess, that's for sure.

 

BUT: I'd say 99% of what you need IS in there, and we'll know more when you ground it (as you say the earth wasn't connected) and see if it runs. If it does, then all you have to do is some tidying.

 

Anyway: I'll try and work through what I think are the questions in your post that I can answer.

 

Pic#1

That yellow wire coming out from the Mi16 ECU is the fuel pump wire. It goes to white wire#76 most likely in the 6pin brown multi-plug in pic#2

 

Pic#2

Yes. They are the 6pin & 9pin brown multi-plugs.

 

Pic#3

What loom's that part of? The ECU loom? If so it should be in the engine bay. Otherwise I'd say it will have a home on the fuse box also pictured.

 

Pic#4

Slightly confusing. What GY wire are you talking about? The one from pic#3? As the wire you're pointing at in the fuse box is yellow & green, which means it's an earth.

 

Pic#5

The FP wire is #76 or #76A, and it's white. I don't believe that yellow wire is for the FP then and it's easy to find, as you can do a continuity check to wire #76 on the 6pin brown multi-plug.

 

Pic#6

?

It actually looks like {a} it belongs on the fuse-box and {b} that it's been altered already with the 2 different coloured heat shrinks on and just grey wires coming out of it. I could be wrong, but it doesn't quite look OE.

 

Pic#7

It looks like you've already started piecing it together and proves some of the above, especially about FP wire 76.

 

I think you've been sent some wiring diagrams - and if you haven't they're in the Haynes manual and downloadable on here anyway - and the wires should all have numbers on, eg #76, so you can look up exactly what they're for.

 

Good luck. Keep battling on.

hello, just managed to get my car to work last week where i can work on it during lunch times and get a hand of a mate if i need it.

 

Ive put a new chassis earth on the car as the old one had snapped off.

 

I was just wondering if anyone knows on the car where the ignition live comes from that goes to the FP relay to feed the FP? On my haynes manual it looks like the same ignition live that feeds the ignition module but i dnt have that either.

 

Also wondering if anyone would able to take a picture on there MI16 (with MI loom) of the Ignition part of the loom that goes to the igntion module and coil?

 

Cheers Keir

[simsk 1]

does anyone know where the ignition live comes from that goes to the FP relay to feed the FP?

 

is it supposed to come from the fusebox? if so, anyone no where abouts?

 

please, anyone?
