Double check your leads, in my experience just because the lead creates a spark at the plug doesn't always mean a good spark, and fuel needs a good strong spark. Even the slightest split in the lead is a weak spark, change em. It may however be nothing at all to do with the leads. Are yopu getting good fuel delivery to the injectors? Any signs of damp around the fuel head, the gasket sandwiched between the 2 halves can deteriorate. You can strip this part but it's not advised, there's a lot of fiddly stuff in there.
