Suzuki Ignis Engine in a Sammi

[twiss]

hahah I didnt say i didnt like doing electrics, I just think its extra stuff to break! Scottie's got the right idea, only use the bare minimum!

Right a bit of help required please.

I've totally disregarded all advice re keeping the loom to a minimum, 'cos I'm getting a bit excited and want it running.

I've basically got both looms in the car at the moment all lived and earthed up. All plugs seem to be connected except for the obvious like Ignis lights, electric windows, wipers etc...

I've even got the Ignis dash hanging in the engine bay, and it all lights up as expected with the Ignis key.

But the small trigger wire that goes to the starter solenoid is not seeing any juice when the key is turned.

If I swap over to the Sammy solenoid trigger wire, the engine turns over, but no sign of life.

As the Ignis had some form of immobiliser, is it possible due to the time it's not been connected it could have died?

Any pointers?

[ScottieJ]

sounds confusing to me, have you got both ignition barrels wired up then and turned on when trying to start it?

The immobiliser in my GV is a small silver box like this, not sure if the ignis does? If so is it connected?

Mmmm, me too.

I've got this wired in. I believe it to be the immobiliser.

The Sammi never had an key, but a battery isolator, all this is turned on, lights work etc so I presume the Sammi loom is working fine.

The lead that went from the isolator to the starter, the heavy one is now connected to the terminal that would have gone to the + on the Ignis battery. The idea being this energises the Ignis loom. This is live as the dash is lighting up.

At the back of the ignition switch I am getting 12v some permanent, some switched, and the one I believe should be the starter trigger goes live on the final turn of the key with 12v.

I have checked the spade that connects to the starter soleniod to the switched ignition live for continuity and all seem fine, but it doesn't give any volts when turning the key

This is what makes me think the immobiliser is not triggering correctly.

Any ideas on how I could check this?

Looking at the only (free) workshop manual I could find the immobilizer cuts out the ignition and the injectors. It shows the starter circuit connected as normal, so it should turn over ??
I think the coil antenna for reading the key code is built into the immobilizer control module or is it fitted nearby.

[Darrell]

Why didn't I just look first ...........

Yes it is ..............

So why won't it even turn over.... I dunno

[Ladaman]

Even stranger now.

I've got the whole ignition bit as per the pic, so it should crank, but not fire with an immobiliser issue then. I can't get it to crank with the Ignis loom.

Darrell could you post me a link to the manual? I've searched and failed to find one myself.

[Darrell]

Urm No!!

I downloaded it weeks ago when you asked something (Can't remember what) and I can't remember where I found it as I searched shit loads of sites before I found it.
I must be getting old

PM me your email and I will send it via "Yousendit" as it's probably to large a file to send direct.

Ladaman - if you're trying to convince me to forget the standard loom and go for a custom loom and megasquirt, you're doing a bang up job!

Hope you get it sorted mate, I don't even have the faintest clue what the problem could be! All I can think of is try finding out which pins on the ECU do what, and use a multimeter to measure the lines responsible for injectors, spark and starter to see what they do when you turn the key - maybe that'd give you an idea of where the problem lies.

Sorry if that's a stupid idea for whatever reason, I know nothing about ECU's. Don't they usually have an output to plug into a diagnostics computer/laptop? Would that be a possibility?
