It looks to be ok. How much does it cost?

it could also be your neutral safety switch. test both of them, test the relay to see if the magnet contacts and lets current through. if it does, check the neutral safety switch, it might be stuck open. and if that doesn work then check the grounds on both =)

Not sure why you started a new thread when people have already been helping you on your previous thread...

Merged threads.

I was reading over the fsm. Check the clutch switch, and the theft warning relay #2. I'm leaning more to the clutch switch.

There is a neutral safety switch, but I've yet to see any proof it does anything. It's located on the transmission. There are two switches. One is the reverse switch. The other is the neutral switch.

Well the relays I got weren't the right ones... No one has the right ones I guess it's something u gotta get from a Nissan dealer? And I was looking on the Internet and seen someone jump the wires from the clutch inhibitor switch (I have a brand new one) to a harness just above it and says it works. Does anyone know if this will work and what wires I need to put together?

It'll work just fine. That's all the switch is, an on or off switch.

Theirs only two wires on the switch, just cram a wire between the posts when you unplug it. (like I told you to do in the third post.)

Ok well the clutch switch wasn't the problem. The clutch inhibitor relay isn't the problem. What else could it be?

Try jumping the solenoid and see if the starter works.

it seems to be that if it is either hot out or the engine is warm it is harder to get start or just doesnt start at all..

No. I really don't think it's the starter just Bc it's only sometimes and when it does crank it starts right up

Have you tried what I said? Also an intermittent starter is usually a sign the starter is going. it's three bolts and a screw and 5 minutes to remove it and you don't even have to jack the car up (unless you lowered it)

If you come on here asking for advice and don't take our advice/ignore our advice, then you should really just stop posting about your problem and ignore us completely.
