Hi, I have a stock 1978 280z that is in pretty good shape (pretty much all original as far as I can tell- no engine nor drivetrain mods). In the last week the engine is been dying frequently when I engage the reverse gear.

If I try to start with the clutch in but the lever in reverse, the engine will attempt to start but it will not keep the engine running; only when I put it in neutral or in a forward gear. Could this be related to either the reverse switch or a clutch switch (that closes the ignition circuit? I'll appreciate any tips/leads to troubleshoot this puzzling thing. Thanks. Raul.

Weird...

What happens if you disconnect the reverse switch? If the problem goes away, it might be some sort of weird short. Do the reverse lights shine brightly, or are they very dim?

Is it possible your clutch isn't fully disengaging?

Hey, welcome to the community, Raul! :-)

When you start the car in gear, does it try to creep forward? I am suspecting the clutch.
