Hi again
The saga of my 1.6 CTI continues.... I originally started a forum relating to Tachymetric relays which which also embraced the subject of ' no power at injectors'. After investigation a melt down in one of the wiring looms appeared to be the problem. After reconnecting the wires the car started and all seemed well enough. I didn't run it for long without the AFM etc but after putting it back together it became clear that it was only firing on 2 cylinders..no.s 1 an 4. It starts first time and doesn't actually sound too bad. I have changed the ECU (to no avail) even though I couldn't see how that would affect only 2 cylinders? I was minded of Anthony's comments in another forum regarding Haynes wiring diagram and their accuracy and looking at their wiring diagrams I cant see how this problem could happen. I am led to believe these injectors are powered in pairs. The Haynes wiring diagram looks as if they (injectors) are wired in series? This problem has to be linked to the original wiring problem but after much deliberation cant see a logical troubleshooting route?
With the engine running there was 12v either side of the injector connections on cylinders 2 and 3 and although that didn't seem right to me from what I have read that may not be a bad thing?
That said I am not sure what to do next and would appreciate any comments. There is a good blue spark at all 4 spark plugs etc., plenty of fuel . Again it is injector related but I have only managed to solve half the problem. Other than stripping back more wires is there anything I have missed?
Thanks
