poor cranking when cold

Actually the startermotor by itself isn't cheap at all a 100 amp upgrade battery is cheaper...

As I said the battery will be a fraction of the cost of a starter motor and fitting....

Just upgrading the battery will not resolve the problem.

9/10 starting problems are because of the battery, not the starter motor.


Also, you mention it definitely won't be the wiring????

Over time the plastic and heat protection wear down, as does anything. A tiny fraction of the insulation can allow water into the wire, creating resistance and causing different faults.

Everything is diagnosable using the correct methods. Don't just assume what the fault is because your car had that problem.


Don't replace parts willy nilly as there is no need when you can diagnose everything. You might as well just throw your money in the bin.

To be very blunt, if you aren't 100% then don't tell someone it's definitely that, as you have little to no knowledge and it's not your money you're ****ing down the drain.

Like I said before my car is a preface 17 year old dti.. my wiring on my car wasn't in a bad stated.... his car is younger so why would that be in a bad state? Yeah no reason at all... it is one of the things vauxhall didn't skimp on.... anyway 9 out of 10 times it isn't the battery that is the problem but the startermotor as they slowly wear down

Also a standard lead car battery last for about 4 to 5 years than slowly they start to loose their ability to hold a charge unless they are put on a trickle charger..

So if that battery is being put on a multimeter and it doesn't drop voltage below 12v it is still fine.

And to make sure it is the starter motor, remove the relay for it and bridge 30 and 87... if the car starts up immediately that means the starter is fine... if it keeps turning over for more than 5 seconds the starter has had it...

Ps

Your rant is absolute over the top and clearly you are the type that thinks he knows everything... you don't neither do I.

But with the age these cars are nowadays, 9 out of 10 times it is the starter motor that causes the slow crancking when the engine is cold. Nothing else.
Again the wiring on a 1.8 is even less prone suffer from engine heat as it doesn't have a turbo, nore a downpipe running next to it. And yes the wiring is routed in a heat shielded abs tunnel, than the wiring is wrapped in heat shielded isolation, before you actually can see the wiring that is connected to the startermotor... and you would know that if you actually had replaced it yourself on any vectra or signum

If there is a cable problem it would be because it has been messed with but on most cars they are undisturbed since leaving the factory. Especially on a non turbo car...

I see on your profile you're a network specialist. I'm a mechanic who fixes problems like this day in day out.

I'm not here to argue with anyone, only to give the CORRECT procedures of how to diagnose and replace a component.

If I just guess faults with cars I'd be out of my job in less than a week. I don't know what's wrong with OP's car, neither do you. That's why you follow the correct diagnostic procedure everytime. But I'm sure you have much more knowledge from Googling then I do.

It's entirety up to OP who they listen too. Like I said I'm not here to start argument, but us mechanics see people who know much more than us from googling day in day out, gives us all a good laugh I guess.

Yes I studied to be a network specialist... but i have always worked on my own cars so I rarely need mechanics and when I do it usually is because MOT putting on and balancing tires or because I don't have a dry spot to some emergency repair...

I also built a few cars myself, nleuprinted engines myself, from actually boring out cylinders to building up a few special replica engines that you can't just buy anymore... try building yourself a 1.8 16vg60 for instance been there done that...

Oww yes I am no mechanic, but I know how to use my brain... and mostly i don't need to look **** up.

just to let people know fault layed with the battery when i inputed the details on diag tool battery readings were all over the place fitted 85 amp battery problem solved

Glad you got it fixed without messing about replacing parts willy nilly mate.
