my car wont start ! to cut a long story short i jet washed it because the engine was really grimy so i serviced it and changed the rocker cover gasket and fitted new plugs and lead. it started fine after cleaning and moved it around on my drive with no problems then park it outside my house. 2 day later when i started it it ran rough like on 3 cylinders and the engine management light came on, fiddled with a few plugs tired it again, ran the same and conked out now wont start. it turns over freely cam belt not broken but no spark from either coil pack. brought Haynes Manuel useless, brought code reader, ran diagnostic scan and have fault codes P0351 and P0352 DTC States ignition coil a/b primary/secondary circuit have checked fuse 22 OK not sure what to check next.Ian

Replace coil pack itself. You may have damaged it with the water

i dont want to start replacing every thing. it ran fine and seems strange both coil packs would go together.

dont forget to check relay T9.

fuse 22 and relay t9 ok i read link but cant understand. surly the ecu has got to get its power from somewhere. does it come from crank sensers to ecu then to the coils ?
