General No start - Airbag?

[paulharpur1978]

Hi, Just a quick one. My car wont start and I scanned with a topdon tool, here is the fault. Any ideas?

 

[koalar]

No start

Cranks but will not run

Or

No crank

Make a small video of the right dial as you insert the key, wait a second or 2 and try and crank

We often get asked the question my engine will not start, what should I do, and the answer is no idea too many variables, it needs narrowing down, cranking but not firing, starts but then cuts out and so on Here we are talking about, no crank, no weerweer noise, not turning over, not cranking...

Clearly is not the airbag causing it.
What's happening exactly?!

 

[Mike1alike]

So... does it crank or not?

OK, so there is no crank. Here is the video. Thanks for the help Koalar

Well I turn the ignition on and nothing. I will rescan but I will start with fuses and earth's and then have a look at the Starter motor.

 

[Mike1alike]

Yes, do look at the starter motor. I can't tell for sure, being a video I'm watching (and maybe I'm missing it), but by the sound of it the starter motor relay ain't clicking. So do start your check there, see if there is 12 V on both lines and all.

I don't see the oil can or battery coming on and staying on


Usually indicates a faulty block ground

Hi koaler success someone had insulated the small thread that fits inside the battery tray with tape presumably to stop it rusting I took the tape off so I could get the bolt off then the gauge instantly went to 3/4 so thanks for your help

Got the car here for a few day 1.2 petrol 2011 Going to post a few pictures and video of some simple and basic tests My well be a bit random as they pop into my head and might sort them into the proper order later

www.fiatforum.com

Start with the tests above

Or a visual check under the battery tray

Thought I post on here as the information on sealing rings is hard to come by Oil filters 1.2 There's two types notice the engine number of the swap over The early ones are longer, A it the diameter H is the length C is the outer diameter of the sealing ring Also notice the bypass...

www.fiatforum.com

Leave the fuses for now, it's possible to introduce a new fault, let's deal with what we can see

Power and grounds will also effect the airbag but I am ignoring this for now as its more than likely be part of the same issue

This is the oil can that should comes on and stays on untill it's been cranking

There's only one wire going to it, and it uses block ground

It's highly likely block ground is your only problem

 

[Mike1alike]

It's true, they are missing.
@paulharpur1978, was some work done on the car or it just started behave like this?
Do check the ground cable!

Thanks Mike. I removed the relay form the engine compartment fuse box and put a 12v battery across terminals 85 and 86 and heard a click so was happy that's working. Next is the Starter voltage but running low on time here today, so will have to go at this next.

Thanks koalar the oil can is staying on the display so next is the block ground and starter voltage.

 

[koalar]

What am I missing

I don't see them on in your video

Both should stay on at ignition on and cranking
At least untill there enough oil pressure built up, engine turning over, which isn't hapening

Oil and battery should be on and here ?

Do you have a multimeter or test light


It highly likely to be the cable attached to the gearbox

 

[Mike1alike]

the oil can is staying on the display so next is the block ground and starter voltage.

I think you mean is NOT staying on display...

 

[paulharpur1978]

I think you mean is NOT staying on display...

Was just in the car with ignition on and red oil can was on...

 

[koalar]

Then cranking it a few times, I know it's not turning over

Does the oil and battery go out

If it does

This cable under the battery tray is likely

I couldn't locate the earth strap under the battery tray, mine seems to have a different layout.i put a jump lead from the negative to the block and the car tried to start, what do you think of this??

 

[koalar]

Looks like the cable disintegrated to me

Pretty sure if you look at the passenger side chassis rail there will be a wire rotten throgh


It's hard to get a good contact with jump leads

Drives side engine mount I find is the easiest place

Which is why is diagnosed them via the method in links in post 7

But if you replace the cable and you should be good to go

Like this one

 

[Mike1alike]

Yes, your cable is damaged.
And you only made partially contact with the jump lead because you put in on the rocker cover which has a seal. You get good contact if you touch the cylinder head directly, engine mount works too because it is directly connected to CH with screws.

Thanks for all the help guys much appreciated. I bought an earth strap in a motor factors this morning and once fitted, the car started better than it has in a long time
