Hello, I have a 1988 Mercury Tracer 1.6L Fuel Injected. This is
essentially a Mazda 323 engine. I am having a difficult job in
resolving why I cannot get cylinders 2 and 3 to fire.



Why would would this be happening? There is fuel, there is
compression and there is spark. Why is there no explosion in the
chamber? Am I missing something obvious here,
electronically?...mechanically?.



Any help would be greatly appreciated.

Allan Dawson
