5 Speed Swap in Progress...NEED YOUR HELP!!!!!!!!!!!
Ok fellow orgers. The day has finally come and me and a couple other guys did the 5 speed swap on my car today. We did my friends car about a month ago and it went well. So we finish my car with the exception of filling fluid in the master cylinder and bleeding the line. We just wanted to see if the car would start. IT DIDN'T. We don't know what the problem is. We made sure all harnesses except for the 4 that were connected to the auto tranny are connected back .We triple checked everything and we can't find the answer. Its getting fuel because we can smell it when I try to pump the gas and start at the same time. If anyone has any ideas please let us know. Thanks. Mike.

It is actually cranking and not turning over. The engine was fine before we did the swap. The only time my engine never started was if the battery was dead or when the crank position sensor went dead. Even when it was dead it would start but would take a coupole tries. But I never had any major problems with the engine. I think it is electrical as well but don't know where to start. And as I said before.....we reconnected all harnesses but I iwll take you guys advice and check the crank position sensor. Is that something I had to remove from the auto tranny? I'll check between the engine and tranny like you said for this sensor. Anyone else have any ideas? Thanks for the help guys.

A Little better explination of the problem would be good

I will defnitely do that. Thanks for the help guys. I will give an update later once I get back to car and try all these things. But if the sensor is dirty.....how do you clean the sensor?

We took out the auto transmission ECU all together. But I'm not sure if that has anything to do with what you are talking about.

The 4th gen actually has 2 ECU's. The main one and transmission one. We took out the tranimission one. I tried the auto ECU and the 5 speed one and the car still does not turn over.

well if it doesnt kick over with the auto one it's probably because of the park neutral switch(it was on the shifter so you should have a plug there now. i still think that the manual tranny computer probably has the wires different than the auto, so it shouldnt work.............or the clutch safety swich wire comming out of the computer has to be bipassed(which could be the same location in the plug is the wiring is the same inside, its just running toward the shifter in your car instead of the clutch pedal). if you dont have a fsm with the schematic to see if the wiring in the plugs is the same it's impossible to know which way to repair it.

Actaully, yeah, he's right. If you didn't wire up the park neutral switch bypass like you are supposed to, you won't start. Look up the 5spd swap writeup - it shows exactly which two wires to connect together.

Just to update every one, IT STILL DOESN'T START. We tried everything from the crank position sensor, new MAF, checked all fuses, popped the clutch and nothing worked. Just don't know why its not starting. I will take it to Jeff at Maximum Tuning and see whathe says. Hopefully he has the answer. Checked all the codes and all we got was the code for the auto transmission for the auto ECU that is still in th car. I will update once I talk to Jeff at Maximum Tuning.

Ok....so here is the update...turns out a few org members were right on the money. I got the flywheel from my friend that went aftermarket. Seems that when you do that there are these teeth that you bolt to the back of the flywheel that you must have for some reason. So when he gave me the flywheel no one realized that the teeh were removed from his stock flywheel and put on the aftermarket. And what sucks is that you can't get this part seperate because it only comes with the stock flywheel. Lucky my friend had one from a maxima he bought and stripped. My car should be coming out today.....EVERYONE CROSS YOUR FINGERS.
Thanks for the help guys. I'll update later.

so it was just an issue with the aftermarket flywheel? I've read a few threads lately that deal with this. the aftermarket flywheel and transfereing this extra attachment that is to help the starter something like that. At least you figued out the problem

With out that smaller ring (signal plate) the car will never ever start. The ring must be transfered from the stock flywheel onto the aftermarket one. This is the situation I've had to deal with with my fidanza.
The signal plate off the auto tranny drive plate will work not either as it is riveted on the back as oppossed to bolted like on the manual flywheel. Even if the rivets were to be drilled out, the holes would not line up on the back of the manual flywheel. So, new holes would have to be drilled. Over all not worth the extra work.
The signal plate is what the pos crank sensor magnet reads as the flywheel spins in order to time the vehicle properly. Make sure that the teeth on the thing are NOT bent at ALL!
Good Luck.

Question I30ds...would the original ring from the replaced clutch need to be used with a new clutch kit from NAPA to work? Could this be why my car is refusing to start when the clutch was replaced? Please let me know... my car is currently at the dealership and they are taking their sweet ole time getting to it...

Ok....we are up and running thanks to Jeff at Maximum Tuning. Thanks for the support guys. I didn't throw the Fidanza flywheel in becuase it didn;t fit over the crank shaft. So I have brand new aluminum flywheel for sale. PM me if interested. $300 plus shipping.

I was just wondering about how much $$$ this cost to do. I wouldn't mind doing this to my car but of course i'd have to have a local mechanic or something do it (if possible) because i'm definatly not mechanically inclined. I'm just wondering how much all the parts and everything cost and maybe an estimated cost of labor.
