Hi Everyone, 

I bought a Fabia 1.4 Greenline in the beginning of the year, and i'v been happy so far driving it to and from work. 

 

One morning last week I fired up the engine as used to and the engine started easily as normal. The engine idled around 4 seconds before the engine shut off. 
I have not been able to start it since. 

 

I need help to figurer out why the thing wont start anymore. I hope a brilliant mind in here could inform me what might cause the problem

so far I have tried:

 

- Removing the glowplugs to check if they work -> they glow like a light bulb.

- Checking fuelpump in the tank --> feed fuel fine to the engine compartment.  

- Changing the fuel filter as it looked quite old --> I bleed the fuel system by filling the new filter and running diesel all the way to the pump on the side of the engine,
   I would expect when I turn the engine without glowplugs that a fine small cloud of diesel would leave the holes but this is not the case. 

- Charging the battery --> voltage looks and cranking power is fine. 

 

Is information regarding what parameters that affect starting accessible?  could it be that if it does not detect fuel temp, pressure, crank sensor, etc. that the engine will never start to protect itself?

 

I have ordered a VCDS tester that will arrive sometime last week.

 

Have a good afternoon

Immobiliser, try with the 2nd key.

Sadly I don't gave the 2nd key, is there another way to test this? 

Update is i have this error: 

Is this enough for the engine to not fire?

No way

Pete, how would you attack this? 

I might be tempted to see what else is fed by the fuse that powers the oil level/temperature sensors.

Can you supply the VIN to allow a build date to be found, and so the best wiring info?

 

Not sure if a stuck closed anti-shudder valve might be consistent with the observed behaviour?

 

 

Hi Pete, 

 

did not see your answer!

 

VIN: TMBGF65J383204657

 

I will check the anti-shudder valve - if i can find it.. xD

A little update on this issue. 
 

Regarding oil level, this car does not have such sensor. I found a thread where other people had similar issue due to software updates. I dont know if this is the same issue here, the fault has always been there. 

I checked the Oil pressure sensor and the connector and sensor works fine, further no error in dashboard. 

 

I tried to bleed the entire fuel line and found that there is some resistance in the return line, is this normal or should it flow with no restrictions? 

 

So after quite some time trying I finally managed to get the car started and running. 

 

So after some time thinking, the only thing that did not make sense was that the glow plugs was always dry when taking them out of the engine. 

so the problem must be the fuel system. Everything worked fine from tank to tandem pump, as that was easily checked. my last unknown was injectors and tandem pump. 

so I did a google marathon in BMS (motor code) tandem pump and found this link from an Audi forum: 

 

I tried to bleed the pump the exact same way as the guy in the forum suggested but without any luck. A few hours later and a Tandem pump in a lot of pieces I managed to conclude that the procedure was a waste off time.

I ended up having the feed pump running for 2-3 min while trying to drag fuel with the vacuum tool out of the fuel return line on the tandem pump, connected the fuel lines a again and then the engine started. 

 

Afterwards I took the car on a long test drive where some strange behavior randomly occurred. 20 min into the drive a bang followed by turbo noise removed 90 % off all house power. I checked the engine and observed that the turbo pressure hose had disconnected itself. After connecting the hose again the car now drives fantastic. 

 

So CONCLUSSION:

 

A combination of a tandem pump that was difficult to bleed and possibly leaking turbo pressure hose was my combination to a great headache. 

I recall having a problem bleeding a Volvo D40 engine on a couple of occasions - it turned out that engine had stopped with the pump cam lobe in raised position both times - simply barring-over the engine on the starter allowed full stroke on fuel pump to bleed properly.
