    I also checked the resistance on the newly installed stator. Each reading just zeros out. No reading. Does that make sense???

    Any recommendations for next steps.
    Black meter probe goes to engine ground.

    Only the power feed wire to the injector connects to meter red probe (via the paper clip).
    Make sure the paper clip really is contacting the metal piece inside the connector.

    If there is still no injector voltage, or very weak, you need to start tracing back, make sure you don’t have a broken wire in the injector power feed circuit. There may be a diagnostic loop-through connector. If so, make sure it is plugged in.

    I do not have the wiring diagram for that model Kawasaki handy so zi don’t know what wire color you would be tracing.

    Well, the EMM may be broken (again).

    Repeat failures from that ‘repair service’ are, um, not uncommon. The EMM are not rebuilt.

    In addition, there seems to be only one aftermarket fuel pump that does not push excessive amps through the EMM. The other pumps all demand about double or more compared to genuine OEM. The result is the EMM control circuit for the fuel pump overloads. If you are lucky it just shuts down the fuel flow and recovers.

    Sometimes the aftermarket fuel pump current draw cooks the EMM fuel pump driver and the EMM needs repair for that.

    In addition to whatever might be causing the weak/non-existent injector voltage.

    So I took resistance readings from stator and got all good readings. I took off the cover and here are some photos. It appears the plastic ends of three coils are broken. Any ideas how this could happen? It’s a new stator from Jet Unit.

    The emm works, I ordered another stator just to check. Not sure that’s the problem since ohm readings came back okay. Someone told me it may be the starter capacitor. But could it be that and still start if I spray some fuel in the spark plugs holes?

    What does your flywheel look like?

    What is the voltage on the BK/R injector wires when cranking? When running? (any, they are all connected electrically).

    Needing starter fluid is a classic case of low injector volts when cranking. Either due to an issue with the stator/flywheel, or the EMM. Based on where the EMM repairs were done, the EMM cannot be ruled out as a suspect. (I fix A LOT of them after they've been to the other guy first...)

    Looks like you damaged the stator coils when you installed the stator cover. To me, it looks like the coils made contact with the flywheel magnets. In the future, buy some extra long bolts at HD and cut the heads off. Loosely install a few in the stator cover perimeter locations. Use them as temporary locating pins when installing the stator cover. This will prevent misalignment/damaged parts.

    What do you charge to diagnose an emm?
