The starter relay is in between the battery and the fender... it should be blue, (that is the original color.) Is that an automatic or standard transmission? Look on the transmission to see if perhaps the wire harness broke, or if there is a sensor that might be unplugged. I had this same problem it was the harness, it broke. I replaced two sensors on the transmission, the speed sensor and the neutral safety switch or sometimes known as the backup light switch.

Well your problem is definitely an electrical one. If all your fuses are good its most likely a relay or the neutral safety switch. DL a fsm and check those 2.

Also, you could take a wire and jump your car to at least turn over. Take a wire from the positive side of your battery to the starter lead itself. This will crank your car, and might help you isolate your problem.

There is no neutral safety switch. There is neutral switch which does not affect starting. There is a clutch interlock switch on the clutch pedal that closes and sends ground to interlock relay when clutch is depressed.

there is tutorial called starter trouble-shooting-engine wont turn over in my signature

For experts:

3.WARNING: PUT THE CAR IN NEUTRAL or car will move by itself for the following procedure. Disconnect the harness plug at the starter. The wire is black with yellow stripe on my 1991. . Connect this wire directly to positive post of battery FOR A FEW SECONDS. Without the key in ignition at all, the starter motor will crank the engine. If you want to start engine , key will have to be in the "ON" position. ASSUME THE ENGINE WILL START without key in ignition at all, for safety.

If your engine turns over when you supply 12v+ directly to black/yellow ignition wire, you know the problem is the ignition, interlock relay, wiring or clutch interlock switch. You then bypass these individual components to isolate the problem. Clutch interlock switch is often broken.

if you drive an automatic and its in nuetral then it won't start. if the electrical components think that its in nuetral it won't start. something might be stuck.probably the neutral safety switch.

What are you talking about? the car WILL start in neutral.

[DroptopDrifting]

the car will definately start in neutral. i have an auto vert, when i park i put it in neutral, rip the ebrake, let go of the foot brake, then put it into park. do you know how many times i forgot to put it into park. it's fine. only prob is you cant get the key out without it in park cuz of the lock. lol
