2.9 Fuel Injectors (maybe)

[TMRnoV]

Hi All, Car (S2 2.9) is only running on 5 cylinders, I have changed the dizzy cap, HT leads, rotor arm and plugs, no change still on 5 only, what should the next step be ? fuel injector ? and if so anyone got a part number or source ?

Cheers

Hi and thanks for the suggestions, and thanks Mark I will drop you an e-mail, actually hoped I'd you see last night at the Corn Mill but understand from the other guys that your not around during the week.

Anyway it's cylinder number 4 that's not firing, after fitting new leads, plugs, cap and rotor arm surely it can only be that cylinders injector that's faulty, I'd be very unlucky to buy a faulty cap, unless of course it's the distributor ?

Other than that the only the other thing is low compression, feel the need to buy a tester coming on.

OK thanks chaps, I have checked the spark at number 4 and that is good (used old plug and marigolds) the plug in number 4 is dry so no fuel, can we say categorically that it's an injector at fault?

Thanks for all of the advice/help guys but I have sourced some new injectors (6) and they should be delivered tomorrow, taking the plenum and throttle body to be soda blasted as well (I know it doesn't contribute to the poor running but they will look nicer )

Probably get the old injectors serviced as well, always good to have spares.

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

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 should it be like that ?

Thanks Simon, one less thing to worry about then no jubilee clip or similar at the plenum end though, still didn't leak and no flames

[TMRnoV]

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 but after that it was fairly plain sailing.

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

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