Hi Guys

I bought a 306 dturbo 1997 as a runaround whilst i give my 6 some tlc!
I have been having sum problems with it and think it may be down to the injector pump here are the symptoms and what i have done:

Symptoms:

Car will only start if bumpstarted or the squeezy hand primer on the fuel line is primed before turning key

Engine misfires under 2500rpm and smokes and will not idle

So far I have thoroughly cleaned the fuel system changed filter bled thoroughly and still no difference have also put additive into diesel and run neat through the pump via the filter housing and still no difference! Any idea's??
