non-starting 240sx

[mike1969]

I have an 89 sx that last week failed to start. The starter is good as I can jump the solenoid wire and it turns over. Is there any other switch to check besides the key switch? I know this is extremely basic issue but I dont have a manual and its to damn cold outside to spend alot of time jacking around with it.

Check the clutch interlock relay: I'm pretty sure it's used for A/T as well, if that's the case. Located in the engine bay, passenger side, near the front. To test, swap it with a similar colored NISSAN relay(the Nissan relays are all interchangable by color) that you won't need at that moment, like AC fan relay or something.
