Glad that's not one of mine biggrin the new injectors cost less than test and clean/service so a bargain wink

Taking the plenum off and all the other associated gubbins has given me another query though, I thought that the fuel line from the pump to the the injector rail was all high pressure plastic, mine just has the high pressure stuff coming off the plenum for about 100mm and then goes into what looks to me a normal rubber fuel line confused should it be like that ?

Yep wink and generally runs at no more than 35/45 p.s.i as does most EFI injection cool unlike an high pressure injection system like the K Bosch Jetronic continuous inj system for example at 75 p.s.i primary fuel pressure eek (i.e Granada 2.8i early & 2.8i Capri) properly specced rubber fuel line works just fine as long as its changed when it starts to crack/deteriorate on your EFI style inj scratchchin a few poorly maintained TVR V8 cars have been burnt/destroyed due to not observing this rule though frown

May of misread that but with rubber fuel hose i strongly recommend suitable clips (not Jubilee style though) but proper fuel hose clips readily available online or offline.

Simon, you didn't misunderstand, no clip of any description where hard plastic fuel pipe pushes into softer rubber fuel pipe, just pushed in and left like that, potential leak right over the exhaust manifold.

Just an update, got home from work a bit early today so set about the tiv again, new injectors were a bugger to fit as was getting the fuel rail back on grumpy but after that it was fairly plain sailing.

Started up after half a dozen cranks and now runs on 6 as it should biggrin checked for leaks and all good, but, and there's always a but, my speedo which was ok started to mimic the rev counter confused

Some thing electrical I assumed so disconnected the battery, now it's stuck at 55, any idea's ??????
