Please help me!
I have a 1993 Infiniti G20 (131k miles). On Sunday I drove it for a while to get gas, when I turned the car to leave the gas station, it decided not to start. I put the key in and started the ignition. I can turn my key all the way to the start position and, although all the diagnostic lights turn on as usual, there are no noises or clicks.
I tested the battery and it's fine.
I had someone else try to replace the starter, and that seems to be working fine.
At this point I'm running out of money (my scholarship ended so I have tuition to pay for as well) and options. Can anyone please tell me what else could be wrong?
THANK YOU for all your help in advance!!

On a budget: Ok - how did you test battery and starter (pic of starter above) ? Did someone just "try" to replace the starter or did they?? How is it that it seems to be working fine? Is this car stuck right now?
This could be a neutral safety switch but let's diag that first. Try with key in just run moving the gear selector out of park and thru them all and back - try to start and also try it in neutral - may work and let us know.
Some cheap must have tools: WalMart - 12v test light $3.96, Pair of test leads/jumper wires (red-black with alligator clips at each end) just $2.96. If you want to splurge get the multimeter for $9.96. Are we in budget?
Just take note of the pic right now. I/we might refer to it later for some places to check, hit with hammer or something

we not only tested the battery with a volt meter, but also hooked up jumper cables with another car. He also ran the starter directly from the battery and the starter worked fine.
We did try the selecting different gears and starting... no luck :(

Ok: Is this to say when just jumped battery to battery it still didn't work but did if you went with a battery cable right to the starter? I think that's what you mean.
In the pic is a large cable and a small one out of sight in that pic. The larger stays at battery voltage. There is a connection from that to the starter that would bypass the solonoid which is the smaller job on top where all the wires connect. If you touched the smaller wire with batter 12v it should engage the starter. Is that what you did that made the starter work?
What's happening there is your key gives a low dose 12v (smaller wire) to that solonoid which is a heavy duty switch which essentially connectes the battery right to the starter with a little wire to your ignition instead of trying to run a heavy cable to one switch in the dash - all cars do that in some manner. With a test light or that voltmeter you should detect 12v at the little wire just when the key is turned to start - we need to know that.
That little wire goes thru a switch at transmission to only allow current thru it when the trans is in Park or Neutral and in standard shift cars detects that the clutch is pushed down - - all that so the car doesn't take off if you are in gear.
You are getting no sound at all with just the key so I doubt there's that intermittent voltage is getting there. Again if you just did that with a jumper wire it should start or crank anyway. If not the solonoid might not be making the switching action. Need to know just what wire and size you jumped that did work.
Just back from WallyWorld no less and those jumper wires are only $1.57 - 3 feet each with the alligator clips. Volt meter can work as a test light - just that some are harder to use for just detecting any current.
Hit back - I'm a little confused as to just what worked and what didn't when you said going direct,
