Xu10 J2Te Cut Out And Not Starting

[NFS 32]

Dont know the AA man tested it, im useless with electric.

[NFS 32]

Does anyone know what these two green wires could be? could they be for the keypad? if so that would explain why they are soilded together and infact is not my issue.

[welshpug 1,661]

TELL US WHAT THEY ARE CONNECTED TO!!!

[Slo 283 1 Cars]

They wont be, or weren't rather, connected to the theoretical keypad. The only reason i can think of for this kind of bodge is to hard wire the fuel pump that the ECU controls!!!!!!!!!. SO..........

 

As above you need to tell us which pins they are connected to.

[NFS 32]

Looks like its pin 3 on the brown plug

[Slo 283 1 Cars]

and the other one?

[NFS 32]

I cannot find where it goes. It gives a reading on both wires when I put it on pin 3

[Slo 283 1 Cars]

pin 3 should be switched live from the ignition it should also be linked to pin 27 on the ecu. so trace those green wires to the ecu plug and see

This is the pin that is on the other end of the two soldered wires

[NFS 32]

What are they for?

[welshpug 1,661]

depends which pin that is.

 

both wires wont be going there, so you need to carry on buzzing through till you find where else it goes.

[Slo 283 1 Cars]

Well thats the right pin alright so im making a guess that the other wire that you cant trace goes to pin 1 or 9 on the double relay plug

[NFS 32]

I checked all the ecu pins and that was the only one that registered. Does anyone have a pinout for this ecu so I can see if rejoining these wires will fix my problems

[NFS 32]

So what are these wires for?

[welshpug 1,661]

as in look elsewhere on the engine loom, not the ecu plug.

look at the links on page 1.

[Slo 283 1 Cars]

Hmm someone has made a right pig in a poke there but theres a diagram on this page how it should be wired up.

[NFS 32]

It goes to this plug that is next to thee ecu

[Slo 283 1 Cars]

What does the other wire that's soldered to the other one that goes to the ecu pin 27?

 

Looks like an ignition amp extension connector to me

The two picture I posted are where both wires terminate. According to my MM

[Slo 283 1 Cars]

So your saying pin 27 on your ecu is wired to the middle pin on that connector through those soldered up wires?

[NFS 32]

Yeah twhy?

[Slo 283 1 Cars]

Can you pull back the rubber to see if its got any number on the wires of that connector.

 

Whats it connect to?

 

I've got a turbo wiring loom out in front of me right now to compare too.

Thank for your help guys. Real credit to the forum!

 

I put the loom back in and have now got it running again. I didn't connect those green wires and have insulated them. It's running now however it's not very smooth to drive like it might be down on power abit juddery on light throttle load. Any ideas?

[Slo 283 1 Cars]

Is it just me?

[NFS 32]

Huh?
