    I threw on some spare crank and cam sensors. And I'm bringing a spare MAF this weekend. Those are the only things I can think of that would cause a no-start situation. Fingers crossed.

    Other components that I considered but rejected:
    Coil packs. There's two, so if one were bad I'd still have half of an engine.
    Coolant temperature sensor. Would make the car run badly, but wouldn't lead to a no-start.
    Air intake sensor is part of the MAF.
    MAP sensor - It doesn't have one.

    Hopefully I've got it. Replaced the crank and cam sensors. Car worked for a bit, then stopped working. The pump ran but developed no fuel pressure.

    Dropped the tank, retrieved both socks, and refit the original pump with a new sock. All appears to be well now. But I'm bringing plenty of spares to ECR just in case.
