172 starting issues with some clip info....

[Ander3670]

Hello all i have been on here and posted a few things since owning my 172 the car will not start but turns over i have bought the clip diagnostics off ebay which has steered me down the right path to fixing a few things but the starting problem has me stumped.

Right down to it here are allthe systems with faults

I'd say it sounds like the immobiliser is the problem. That usually lets it crank but wont fire. What's the red light on the dash doing when you try and start it?

Could also be the battery going by those low supply voltage faults. I'm sure these cars love to throw all sorts of issues if the battery isn't that great in it. (I don't know how to read clip codes tbf, so I might be talking out my arse here)

Red light flashes like normal then goes out as it should, with regards the battery i have charged it with no change its really busting me

Id say it's the crank sensor. When that's fubar then the engine will crank really quick for a few seconds but not fire. It's also known as the TDC sensor on here. It's above the gearbox right under the throttle body side of the engine.

It can just need a clean but you might as well replace it whilst you're there imo.

It's under the thermostat housing. It's the drilled metal plate and two bolts in this picture

Just try erasing those faults and see what happens. IMO those faults in petrol injection shouldn't stop it starting. Also if you click on the box to the right of the description of the code it will give you the conditions of the fault i.e short to earth, coherence e.t.c.

Can you click on the down arrow on the bottom of the screen as that will bring up more faults by the looks of things

Welsh name its not tdc sensor its fine,

Clio ben most of them come straight back and on the right alot of them do say short earth or low power. But the battery has been getting charged with same results. Il have another look on clip to see what they all say

first port of call is fusebox under the bonnet.
