Wiring problems 1.4 to 1.8 grr

[AmDaMan]

Hey all, the engine is finally in, all wired up etc but the fuel pump wont prime, been told that this may be because to looms are slightly different! We plugged the looms into the black box near the passenger wing, and 2 wired started to fry on the white plug?

On the valver there are more wires going to the white plug than the 1.4 (there are 2 black ones on the 1.4) It also looks like the wire arrangement is a bit different on the brown plug. The 1.4 is a 94 and the valver is a 91 btw.

My question is, what should we do? Will we need to take the entire loom that goes behind the dash in the valver? Also where does it connect up and how much do I need? Alternatively how do we make it work as it is?

Some pics:


Valver loom, where should it be disconnected to enable it to plug into the 1.4's?





Valver plugs, the white plug only has two wires on the 1.4.. I'll get pics of the 1.4 plugs tomorrow.

Cheers!

To stan in the other thread: What does the white plug do as we have left it disconnected for now..

The pump is now a valver pump, you can't hear it prime though.

The old engine was an injection.

There was an immobliser but that has been sorted, also how do I check the voltage at the points I need to.. eg, ecu, injectors etc?

sounds like the usual live to fuel pump from ecu not matching.

You can put an ign live to it to make it work.

You need to identify which is the fuel pump wire. to do this, check for continuity between pump terminals and each of the wires in the brown multi-plug. off the top of my head its white, and i think its the 4th one in from the left, on the top....of the car plug.

Then run a wire from an ign live (yellow iirc) to the fuel pump wire.

are you getting a spark?

Hi stan, cheers, i'll have a look tomorrow. We couldnt hear the pump that's why we think it's that.

What's the easiest way to check for the spark? Is it something you spray in the TB while someone turns over or by looking at one of the plugs?

[AmDaMan]

ps what are the black wires i fired on the white plug?

[stan]

god knows about the wires.

Pull one of the plug leads off, put a spare plug in it, and rest it on the engine. crank the engine and check for spark.
should be a strong blue/white one.

or take lead off and whack a screw driver in it and earth and look for the spark :D ( incase you dont have any spare plugs)

[AmDaMan]

cheers going to look after dinner.

When you say check the wires from the pump, there are 4 iirc, which one is the power?

So I check that with a multimeter and a long piece of wire to the brown plug and check the connections?

Thanks.

Had a look but can't seem to see what the heck is up with it! Also there doesn't appear to be a spark which doesn't help anything!



This is the relay box, the immobilizer has been connected up.



This is the valver plug.



Where it connects to the 1.4 loom



White plug from the 1.4



Valver whiute plug (addume this is for the clocks, but it's not connected)


Any help greatly appreciated!

thanks.

[AmDaMan]

anyone? Could it still be an immobilizer as there doesn't seem to be a spark either, i thought we had joined the immob wires up though!

how shit. sorry cant help dude. my m8s is basically ready to fire up now. jus gotta sort fuel lines and driveshaft. hope we dont have any probs like this!!
