Hi Guys

having trouble with starting my car , I started noticing it not starting on first key after being left overnight usually 12 hours or more. Sometimes it would start other times would take a few goes before it started but then it ran normally , so it is just the starting problem
I then had the fuel filter changed as I thought it may be that and it was a due a change , once I got it back it was fine again until next morning and then back to not starting?
it seems to try then dies , I just bought a priming bulb and fitted that but still the same it just wont start , it does try but then dies again......It is driving me crazy.

any help appreciated

Sounds like a cold start problem so get the battery and alternator checked. Do you do a lot of short runs. Could be a starter motor problem too. Also worth adding a bottle of Forte diesel treatment to the tank to give the fuel system a clean out.

Dam fords pain in my arse with them when changing fuel filter and they let in air if not tightened tight.
Might need fault code reading,as last week did a stop/start battery and a day later starter packed up ouch.

Hi

I have replaced the battery and still the same , I did get the car started this morning priming the bulb whilst friend cranked the car and ran it fine so I will see how this starts later , my thoughts are that the fuel is draining back after standing for a length of time as it starts fine once it has been run ning…....

Some cars need diagnostics done after a new battery is fitted.

sounds like glow plugs to me mate.
To test your glow plugs, simply connect a 12-volt test light to the positive battery terminal. Then disconnect the wires from each of your glow plugs and touch the probe of the test light to the terminal of the glow plug itself (not the wiring harness).

Hi

Thanks for the reply , I had glow plugs replaced less than a year ago but im not sure the glow plugs could cause this issue as it does start when being primed.
I thought the glow plugs were only needed in very cold weather , but any suggestions welcome as i'm confused what this problem could be , i started it this morning and went on first key so really strange problem as the night before it just would start

Is the fuel filter housing on the side of the head?

I’ve had a look round and found on rac forum someone with a similar problem, same engine 2008. Where the starter motor was causing too much current drain and therefore shutting off the main relay.

This was also advised to the op....

Presumably no warning lights on the dash?
There are a few possibles for this. Air in the fuel system can cause this. So if you don't want to spend money on a diagnostic check it is recommended you fit a genuine Ford fuel filter as some aftermarket ones do not seal properly on the pipes. Or apply some grease to them as a temporary measure to see if any improvement.
The bleed off pipes from the injectors come as a complete kit from Ford. If you see any signs of wetness around any part of these pipes they should be replaced.
Put the car on a PROPER diagnostic test - not a fault code read - and have the garage check the fuel pump cranking pressure when trying to start. It needs to be a minimum of 20 bar and nearer 30 if possible. If good then they must do a 'quantity comparison' to ensure that all 4 injectors are well within the limits. Any error here means the injector has failed (very common). If this procedure is not available on the diagnostic tool then leave it and find a garage that does this (a good diesel specialist will). Next, a leak-off check should be done where the small rubber pipes are removed and test bottles fitted. This measures the amount of unused fuel being returned and if one bottle fills up much faster than the others then the injector is faulty.
During the tests the various sensors on the engine can be checked for the correct outputs.

If the garage simply say 'there are no fault codes' then go elsewhere. A good local diesel specialist or a Bosch Service Centre should sort this.

Also found similar on Ford forum same car 2008.

I have had two diagnostic checks done and nothing showing....thankfully. Just had the starter motor changed and that seems to have sorted the problem.
