Hi...

Not a mechanic, so take what I suggest for what it's worth, but get a long screwdriver, put the blunt end gently against your ear, and with the engine running touch the tip to each of the injectors.

You'll hear the clicking on the good ones, possibly nothing on a bad one.

Do it carefully.

Take care.

Ken

some of those ignition parts you replaced could be bad, also.
