For starters I'll say that I'm not very well versed in cars just yet, the project I have is my first and I'm very much still learning so bear with me.
I've got an 89 240sx, it started when I initially got it three years ago, it sat for about two for those years and now it won't start. I have a mechanically inclined friend helping me out(however he's a Ford guy, so this is slightly different territory I guess) and per his suggestion, the following has been replaced
-Starter and starter relay
-Fuel pump and filter
-Fuel injectors
-Spark plugs
After the point of replacing fuel injectors (one was leaking so that definitely helped ) she sounded stronger? Where there had only been a low whine upon turning the key before, there's kind of a rumble if that makes sense, but will not start. The fan for the radiator will rotate maybe one blade every time I try. There's also a clanking noise when I turn the key and I have no idea what would be making that? Also the ignition switch does literally nothing and once upon a time it definitely helped get it to start.
The consensus so far is that something isn't getting power where it should, but I, once again, have no idea where to go from there.
Any and all suggestions or insight would be greatly appreciated!
