hi there guys i have a big problem with my 21 se going along the road on it and suddenly it started misfiring then cut out re started and then cut out would not start there is no spark at the plugs battery is ok power valves still work when you close them manualy then turn on ignition they go back to start position checked all conections in junction box could the pgm 3 be faulty on the ignition side also with the ignition turned onif you hold the plug against the cylinder to check for spark you get a very weak spark off the earth side of the plug without turning the engine over
