Sparks at start-up.. immediately dies.. HELP :(

[itavaltalainen]

do you have any sort of guide on how to use vcds to test this??

Simply go into ECU (01) - then into measuring blocks and click your way up... there is labels for most things on mk3... just look for throttle angle or throttle position or something similar.

Got it it's labelled t.b. angle for throttle body

It's working perfectly. Measures the angles in degrees from 0 all the way to 73 degrees when it's crushed down..

And yeah I tried the bonnet earth no dice haha.

Thanks for the suggestions, more would be appreciated!!

Did the turning on, leaving it on, key out key in, on, start.

Nothing still only if I hit the peddle.

I am starting to wonder if the alarm system installed is faulty, causing the immobiliser to malfunction?

It's one of the fancy ones that stop hijacking etc so can control the immobilisers.

Other than that I really am at a loss..

If I can't figure it out she will have to be sent to a garage to try and figure it out.. After having a clifford authorised retailer remove the alarm system..


My hopes of having her alive for the summer are quickly diminishing!!!

Throttle body angle stays at 0 when trying to start. If I let the angle go below 5 degrees it shutters and then less than 3 it's out.

Immobiliser no codes. Measuring blocks shows key status 1, engine start permitted 1, so okay I believe

Have you tried do a reset of the immobiliser?
You say its an aftermarket one a Clifford???
You should have some kind of fob that you poke in somewhere

Love it - how do I do that?? If it's what was suggested earlier of turning ignition on, leaving it, off, key out, key in, start, I've done that but otherwise I will try how you suggest?

I've reset ECU by disconnecting battery and reconnecting after about half hour.

Yeah It's a clifford concept 650 I think.. or 630, one of the 6-series.

No fob to insert, it's a remote which locks/unlocks and then you enter a code when you turn ignition on to unlock it.

I called a local clifford authorised installer/service center - guy was amazingly honest and said he can take a look but from the sounds of it he really doesn't believe it's the alarm, because if it was it wouldn't even let me turn the key..

He's right, cause a few times I forgot to enter my unlock code and turning the key wouldn't even let the starter motor start up!

So it seems the alarm ain't the problem.

But yes, how do you do an immobiliser reset??

just seen an older thread where someone hit their icv with a hammer as it was stuck. gonna try that after another clean haha!!

I think it could be a nackard throttle body. I have recently fitted a genuine gasket to it so its nice and clean. If u want i can take mine off and post it to you for 20+ postage. Before buying mine of me. Have you checked the wiring aint split going to it?

[xAntiVenxm]

Had a new symptom now!

Turned the ignition on.. got smoke coming from wires behind the steering wheel!

Thought faulty earth.. wiggled the wires a bit and it stopped smoking.

Wondering if this has anything to do with it!

This weekend going to do a full check over of all the wires and clean anything that looks awry.. There's a LOT of wires that look very dirty and the connector pins probably need a good scrub too.

The fact this car sat in a barn for a year could mean things have corroded.
Apparently it didn't have this issue when it was last driven.

My thoughts are seized idle valve or faulty connections somewhere.

If checking everything over gets me nowhere ill take you up on that throttle.

Smoke behind the steering wheel is common just some dirt build up will cause this so just a small clean up of the contacts
