Technical Need Urgent Help - Car Not Starting

[Mike1alike]

Do you still have the recipe for it?

Quickest way to test if fuel pump is working is to disconnect the quick connection and turn the ignition on

I find petrol to be blue green, as here

Although it's actually clear and dye is added so can technically be any colour

a fowled MAP sensor would cause poor acceleration original symptom and difficulty starting

Does your car have two coils on the right side of the engine, or one larger coil under the airbox

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

I think you should swap out each spark plug one by one, or just change them all. Checking for spark like you're going to is a generic test, it won't tell you if one plug has failed.

And did you try to bump start the car? if not it is probably going to get home.

Sorry I missed the bump start. I am not keen to do this as there is not a lot of space where the car is left.

These engines will start on and run nicely on 3 cylinders

They run badly on two

You can tell if the coil pack is getting a control signal and giving a good spark like this If one is weeker and the spark does not jump as far than the others it's suspect It is possible to get a jolt if you do something wrong, probably not a good idea if you have a pace maker As long as the...

Ya, I expected as much. The "Random Thoughts" sections are great, thanks.

Thanks Koalar. To be clear. The test you are talking about is to:
1) Disconnect the fuel line quick connect - is this the one at the head of the arrow in the image below?
2) Stick the line in a large vessel
3) Turn the key from off to ignition (but not cranking the engine)?
If so how long would you leave it on ignition - just for a brief moment?
How awkward is that connection - is quick connection accurate?

Ya, two coils on the side together. The image below is my car.

I have a spare map sensor I could try. The data below is not great but the MAP data is in roughly the right place. I will try and get a better grab of this data under cranking. Any other data I could get that might help?

Sorry, not sure if there is much to see here. The engine cranks, voltage dropped to 9.5ish V.

I thought you meant the car
I have the receipt as I bought it new from Fiat 16 odd year ago.

Then I realised it was more sensible that you meant the fuel. No, I did not get a receipt for the fuel. I paid at the machine. It was at Tesco and I used my Clubcard - will check if it says anything but doubt it.

Yes

Yes about 1 second

How awkward is that connection - is quick connection accurate?

Push the pipes together ( not necessarily but I find it easier to push the button in if I do this first)
Push the two buttons on the side in
Pull the pipes apart

A few seconds if your fingers are strong enough

Ya, two coils on the side together. The image below is my car

Great it's not a faulty coil it will run on one, badly but it will start

Do you still have the recipe for it?

I looked into this and I can get it retrospectively. Tesco hold it for 30day and I paid by card so they can check this for me. I will look into it, as why not.

Yes

Yes about 1 second

Thanks for the details.

I accept your challenge!

It's a shame I still not got a panda

I have never taken a inlet pressure reading while just cranking

Here's mine on start up

You can see it dips down a bit cranking, as I would expect, the throttle shut (small opening) and the cylinder are still pumping air out

Where as yours is flat lined

But it does depend on scale and sample rate

They can flood if you crank them too long

If you floor the throttle it should stop the injectors and a couple of seconds will clear the cylinders, I say should as I don't know if it works on every model,but it worked on mine
