the whole point of above is to see if ECU is working, and not bad input to it causing ECU to inject wrongly
if the injection pulse are good, the injector is clogged. (lean burn and no power)
that is the test. just that.
46year old scope, all solid state and still works like new. I have modern scopes too.
does not take expensive scopes, mine was $75 used
a scope that can not blow up with -40v back EMF coil kick back will work even one that is only 1mHZ rated.
what matter cars is safe for voltages. up to say 300vdc , like the noise seen on the AC clutch,. or injectors or coil spark primary + or minus lugs. (forget HV spark for now)
