Hi all,  I’ve got a starting issue with a 1994 Audi coupe , 16v 2litre with a k- jet furling system (I believe) on a ACE coded engine.

I have carried out various checks, cleaned the filter - clean anyway - fuels coming through..

the last item checked was the metering unit - cracked each inlet pipe individually to the main injectors but no fuel coming out. The 5th inlet pipe - cold start injector  I’ve been told, and fuel comes out easily.. 

any ideas??  I’m looking at getting the metering unit pressure tested, but could it be anything else??

thanks..

did you check the coil pack?

Hi it sounds to me initially like your metreing head unit is the problem if fuels not getting through. Are you getting a spark? Has the car been stood for a long period of time? Is the fuel pump priming?
