ECM, eletronic control module?... "Need to see if the injectors are getting a fire pulse command from the ECM." Thats right SJ do you know any way of doing that?
Fixer this mower was running another engine just 2 days ago, the pump and relays work fine there is plenty of fuel preassure .... all filters work best when dirty, fuel air or whatever type they just filter more and more until there is no flow .... no flow is easy to detect and one of the first things I would check for... I have flow but it is not getting past the injectors and into the cylinder .... when i squirt fuel into the air intake the engine will fire up briefly.
