New member here with very frustrating crank no start!

[Pat_86]

Hi all, 

So I've had this Audi since 92k, the guy before me obviously didn't care and just regged it around but I loved the car anyway so it's my problem now. It's done 120k and since it has been in my onwership for the past 4 years everything in the car seems to have been been replaced, to the extent where it is now called Trigger after Triggers Broom.

 

 

The current issue is that it cranks but doesn't start.

The car would intermittently start after several cranks, idle very roughly & revs would slightly drop every 10 seconds or so. The situation got worse after a couple of thousand miles then required easystart to get it going. Now it simply cranks but will not start.

 

Vagcom shows no errors relating to the non start just one in HVAC about a heating vent and one about the EPS as the battery has been disconnected and not driven which would clear the fault.

If anyone can point me in the right direction to at least diagnose the issue that would be amazing! Here is a list of what has been changed recently.

 

Kind Regards Patrick
