1.8 16v Zetec Not Firing On Cylinder 3, Help Me Please

[jay knight]

My car is sick and i can't diagnose what is up with it so am hoping that someone knows or has had a similar problem. It is not firing on No 3, the leads have been changed, the plugs have been changed, the compression tested, distributor/coils been changed, the injectors checked. It seems that there is a spark coming to all cylinders and even on number 3 but still the car is still firing only on cylinders in total, once starting from cold it runs fine until it gets warm and that is when the car starts to mis fire, Can anyone help me please as i am stuck and cannot afford to get it put onto a diagnostic machine. Contact me direct via e mail if you can or on messenger or leave me a reply on this post. Thanks

It sounds like you may have a bad injector or a broken wire to the injector on that cylinder. If you are getting good spark then the problem has to be in the fuel system. Check the wiring to the injector to make sure it is in good shape. Sometimes these wires will break and it won't show easily. That is where I would look next.
