    Have you tested for wire continuity to the coil?

    With your DMM on the coil lugs -
    Make sure the power side is hot.
    Make sure the other side is continuous to the TIP 102

    Quoted from ALY:

    As described above the plunger coil works if I test it with some other transistor or if I ground it. It fires.

    I’m not talking about the wire on the coil, but the wiring harness between Q58 and the plunger coil.

    Check for continuity between the coil lug and the transistor leg.

    I don’t really understand what you are saying, but you need to test the specific wire, not the one next to it. Transistor to coil continuity rules out wiring harness and connector issues.
