Audi a3 20,ltr tdi 2005 bkd misfire

[Darrenhannah]

Hi I'm new to this and was wondering if some one could help me with my car problem, my cambelt shed a few teeth so had to stripe my engine down at friends garage, cleaning all engine down and cleaned of old gaskit and sanded with flat bloke as their seemed to be no damage to head and values, even that the valves did mark top of pistons,so I've done a cam kit and had new throttle body and actuator, new glow plugs , both belts and pulleys, new bearings on alternator, I re,ground all the valves so where bedded In,since this I rebuilt it back to get her and have loads of smoke on starting and it give me a code p0301 misfire cyclinder 1 and it misses bad, I've just bought new wiring loom for in rocker cover but it only made it start Easyer, please could some one help me

[Darrenhannah]

Sorry forgot to say that I swapped injector 1 and 3 and still got misfire cylinder1 that's why I got the wiring loom, I've put them back to how they where meant to be but still got that code coming up

Bores / compression ok on cyl 1 ?

[Darrenhannah]

Done compression test and all are about 30 bar so good compression

[Darrenhannah]

Also put new head gasket and all other gaskets,I don't no why it is giving me misfire code even when I swapped injector 1,3 , I have swapped them back and still get code, thanks for your help

[Darrenhannah]

Do you think I should get injectors checked as I have been told it could be injector or 2 and it's throwing up cylinder one as it's compensating for injector 1

[Darrenhannah]

Also I could not start car so had to use easy start after I had swapped injectors, but now starts every time

[Tame Technician]

When the injectors are removed, all the fuel is lost in the feed pipe in the head, it take ages to build up again.

Have you checked the fuel pressure from the tandem pump.

If not, or you dont have the correct gauge try a hose clamp on the fuel return line (the one with the fuel temp sensor in it) near the filter, see if this has an effect.

[Darrenhannah]

Thanks a lot, I will try this and let you now how I get on, would this give you a code for misfire cylinder 1, code p0301

[Darrenhannah]

I put a clamp on the return fuel pipe, left it on their for a min or so the tried it again but this time it cut out and had to use quick start to fire the car up again, any other things you could think it would be please

[Darrenhannah]

I have tryed the clamp on my return fuel pipe and it seemed to run slightly better, so done the clamp again and the engine stopped, I had to use quick start to start it again as it would not start by it's self, is their any thing else I could try that you no off thanks darren
