My ign live feeds under the bonnet have gone dead. Black wire with brown line i think.

They are the ign feeds for the orig loom also I think. It now has a pectel loom

Does anyone know if these are fused anywhere?

OTHER than the fuse box and the aux fuse pod on the battery. Ive checked these and there are none blown.

Strange one.. indeed. Means the ECU is dead and wont start the car. (ive placed a temp live feed to get the car back home and locked up)

cheers

 

I take it you no longer have fuselinks....

BTTT for Dave

 

Black with brown stripe ?

Thats not a normal ignition colour....

Normally black and black/yellow stripe.

 

cheers googlebong

Ding, probably yellow.. come to think of it... deffo yellow

 

could it be the igntion realy

most looms will have a realy for all your igntion lives

worth a shot duno which one it is though sorry

 

so nothing at the coil ?

This comes from the ignition barrell efectively via the fuse board...

What loom do u have installed in the car ?

As the normal cossie loom pick's up its live from the main loom - black wire usually 25amp

 

running coil packs ding... I have a pectel loom. The orig ign live feeds it from the std loom.

no starter, fuel pump, ecu live .. just ign lights.. turn the key and nothing


BUT

feed a live to the engine bay ign live that USED to be live.. then hey presto.. everything starts

somethigns blown... but where is another story lol... all fuses are fine (that i can see)

 

Dave, there's a connector on the left hand side of the battery - sort of on the plastic surround. Make sure thats connected properly!! If you cant find it, follow the small wire from the starter motor bunch of wires I think it's blue and black!!

 

Kev, I checked the fuse block that is connected to the battery... and everything is as it should be. They are much thicker wires also. This ign feed is quite thin

 

i had them burn out on the back of mine - the copper had gone all black and fooked on the two main ones that go from the battery pos lug to the main fusebox - had to chop them back, and solder new tails on them both of about 100mm to get back to decent copper - i think someonw at some point had had the battery on cgarge left on the car and the acid had bubbled all over the top of the battery, cos thhose wires were manky as were the inside of the main cooling fans relay right next to the battery.

 

I dont think I have that problem Dave.. all the links are clean.

These ign feeds come up behind the right hand side turret... they must lead somewhere that's fused .. or unless they've burnt out somewhere...

if i cant find out.. ill re-install a new ignition live to the loom.. but id rather find out what has caused this

any suggestions to take a decent ign live from, either from the fusebox?

 

Is it the permanent live for the P8 (as you have ignition lights)?

 

No Bill.. ign feed

I wasnt aware P8 had a perm live?

 

Not there.......

get hold of the starter wires that come up from the starter and there's a thinner wire with them - follow that and it goes to the LEFT hand side of the battery looking at it. On the plastic surround is a plug - check that!! I had this with the exact symptoms and I found I'd slightly loosened the plug whilst faffing around with the wiring!!

 

It doesnt make sense the car not cranking till you give that wire a live?

That wire not being live with IGN on (as it was) shouldnt affect the starter cranking?

Have you checked EVERTHING electrical works>? Lights radio heated screens etc etc could just be the common old fuse box issue...

BTW IIRC the wire is black alone

 

thats EXACTLY what I thought Damo! I thought an alarm problem... as i couldnt crank etc..

BUT the alarm has nowt to do with the ECU and nowt to do with those ign feeds to the loom...

as soon as i connect a live to that ecu feed... hey presto



something is amiss.. but what!

 

Or an alarm fault, that would cut the starter and IGN feed THAT is becoming my favourite option...

 

And putting the feed on to the ECU is backfeeding to bypass the fault?

 

Possibly.... either way the feed must be "backfeeding" some way, as that wire isnt linked direct to starter/cranking...

 

as a temp fix to get the car back to its locked up safety.

So IF its an alarm fault.. JOY OF ALL JOYS!

where the hell to start looking!?

 

They thing to try would be disconnect the Pectel loom from car loom at the IGN live wire, give the pectel loom a live from battery turn IGN on and try cranking, if it still doesnt crank, then it is a backfeed supplying starter relay etc

 

good call mate , will get on that asap.

 

The only proper way is to follow it all the way from the source testing for voltage as you go, and see where you loose it.

You might want to try finding where the wires from your alarm are spliced into the loom - test both sides of the same colour wires to eliminate the alarm.

 

Does it have a Vecta fitted to it?

They are common for relay contact failures....

 

no daz, long gone mate

 

right, update..


if i just give the ecu a supply.. the car wont engage the starter motor

if i give the dead ign feed a supply ( and the ecu) then the car starts... BUT

I can remove the keys witht he car still running, only way to kill the engine is to remove the temp +ve feed


SO it must be ign based related......


any ideas?

the als relays were plugged in the wrong way and overheated.. these were connected to the +ve ign feed under the bonnet.. this has caused the prob..

The alarm is fine.... just somethings killed the signal to the starter.. inturn killing this underbonnet ign live

 

and the ign live cable is black with a yellow stripe

 

Sounds like immboliser or burnt out wires and u need a this testing.

Try a local Auto electrician.

 

R26 is your ignition relay R24 is your starter relay....

Check for live feed on terminals 30 and 87 of the relays when the relays are engaged (assuming they click on and off with the ignition and cranking position)...

 

R8 is the engine management relay.

 

cool Daz! thanks for that!

 

Daz to the rescue again...

So at a guess its probably the relays or fusebox... If it isnt the alarm??

I'm still not convinced its not the alarm TBH

Why have the ALS relays failed? What was wired incorrectly? Pectel loom?

 

Im not speaking to you, you c*nt!

 

I was in the pub when you text me yesterday

 

im not talking about that!

 

its still there Damo!!

 

dave can u answer my pm's please.

u spud!

 

Ryan

 

pleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeas e

 

ok..


Yes
