mk1 172 conversion

[williamsvts]

hi, im busy fitting a 172 engine into a mk1 1.2 clio shell. i have took the engine out of a clio williams shell.
when i go to start the engine it turns over but there is no fuel, cant here the fuel pump running either.
i noticed in the williams shell where the engine loom joined interior loom it was connected buy a large brown plug, + a white wire from a relay on the 172 loom was joined to a wire on the williams interior loom. does anyone know what this wire is for? as there is no matching wire on the 1.2 interior loom to splice it into.

pic of wire on williams loom, may not be much good.

From what i was told when i was doing my conversion, you need to run the full 172 loom(inside/engine)

The white wire is probably the fuel pump live...

You dont need to run the 172 interior loom at all, we haven't...

which williams did it come out of? not the one done by hill power was it? (from birmingham iirc)

This is the most freaky-est thing in the world. I'm doing the same thing, putting one in a 1.2. Tried turning it over but no fuel etc.

Freaky

My fuel pump was seized as a result of not being used. Cranked it over whist a mate tapped it and it fired up.

Buzzzzzzzz..... Sweet music to our ears! lol.

Ha ha!! turns out its my car! my bad ha ha ha ha

had the car started with easystart today so i know its sparking. still not getting the fuel pump to run. i have getting the brown wire from the fuel pump relay wired up now.
i noticed there is another wire (number 2 on relay), it seems to be grey coming out relay then changes to black within 10mm, this wire is not attached to anything. on autodata it says the the wire from pin2 on the relay is violet and goes to pin 9 on the ecu, but there is already a white wire into pin 9. does anyone know where this wire from the relay goes?

 

[cliosportcraig]

Which fuel pump relay are you wiring in?

Pin 68 is the fuel pump relay control

 

[williamsvts]

the 1 that is on the 172 loom. it had 2 cut wires on it. i have 1 wired up but theres a wire from pin 2 on the relay that im not sure where it goes.

 

[williamsvts]

just checked autodata and it says that pin 68 on the 172 ecu goes to heated oxygen sensor???

 

[cliosportcraig]

Autodata is wrong, a ph1 172 loom uses pin 68

It's in the F4R manaul

HERE

 

[williamsvts]

i thought it might of been, some wire colours were wrong. what program do i need to open that file?

 

[Matteh]

yep, autodata shows a ph2 172 for a ph1!!

 

[williamsvts]

ah right, thats a bit stupid!!! thought some of it was b****cks.

how do i open that file?

 

[Savi]

opens on PDF straight away.

 

[williamsvts]

it asks me what program do i want to use to open it

[williamsvts]

i still cant open it. so does pin 68 got to pin 2 on the fuel pump relay?

 

[williamsvts]

sorted. why does it show ignition coil`(778) as only having 3 wires? when it has 4?

 

[Sean6545]

Yes, its the energiser wire for the relay to work.

 

[williamsvts]

which 1? to pin 68 or to pin4 on coil?
pin 68 im guessing?

 

[williamsvts]

problem ended up being fucked plug on fuel pump. whacked another on and it starts.

^^ common problem that

mine used to do it now and again as the connector pins get worn, uprated fuel pump and connector and its never done it since
