Needing to put a motor in a 200sx.

[Syes200]

Okay I'm in need of some help here. I've been trying to put a GA16DE motor back in my 200sx. This is the first time I've had to put one in cause the car has been good to me up until now. I pulled the old motor and transmission out, at seperate times, and now that I've finally got the new motor attached to the transmission the length is more than the space allowed. So my question to you people is...CAN YOU PLEASE HELP ME FIGURE THIS OUT?

[One_Love]

first welcome to nico

second, check the 200sx/sentra forum

you will not get much help in general

[Syes200]

Alright thanks man

[mould_jesus]

are you trying to put in another GA16DE? and is it one from the same year?

if so then there shouldn't be any trouble as long as the swap is done right.

[nametakennow]

I'm still trying to figure out exactly what the problem is. Are you saying that you pulled everything out, mated the transmission to the new motor, then tried to slip the transmission and motor in at the same time through the top and it doesn't fit?

I find that kind of odd, but if that's the case, just take the transmission off and mate it up on the bottom, reverse of what you did before. It will take a little while, but it's better than sitting around wondering how you're going to do it.

Better yet, try to take the contacting parts of the transmission off, since I suspect they're part of the shift linkage, and reattach them after you get the engine/transmission bolted in.

[Syes200]

Well I got it in, I had to have someone help me but I got it. I've got a new problem now, I try to start it up and it won't stay started plus it's spewing transmission fluid on the ground and I can't find where it's coming from. The motor itself is from a 1998 Sentra same model engine so this one is kinda weird.

[nametakennow]

I suspect that those problems are related, that is that the leak is between the transmission and the engine and it's caused by whatever issue is stopping the car from idling correctly. Check the area around the engine/transmission connections, you may have to pull it back out and take it apart again.

Also, the sig patrol won't like that rather large sig pic you have going, resize as per the guidelines in NICO General Chat if you get a chance .

[Syes200]

Well I got all my leaks fixed, I had my girlfriend get in and turn it over so I could look at it while it was acting up and it was just one of the hoses had pushed itself off a little bit and the I didn't put the CV axle in all the way. Well it's full of fluid now and it's still acting up, I think my MAF sensor my be screwing up and I also found something else that's interesting. I was searching all the wires and found that I don't have a connector for my coolant temp gauge sensor and I have a plug that doesn't go anywhere. The plug is on the driver side and runs underneath the relay box and around the strut housing area, I've searched that area about a dozen times and haven't been able to find what it would plug into.

[nametakennow]

I'd like to think those two would go together, but I guess not.

Your coolant temp sensor is why you're running poorly. Find the connector for it or you'll never run right.

Post a picture of that plug if you can, that may give me a better idea of what it is.

[Syes200]

Okay here's a pic. The plug is laying next to the P/S resovoir.

[nametakennow]

Hmm... I'm going to have to ask for a closer up one too. The shape of it is fuzzy. Follow the cable, see where it leads and where it becomes part of a bundle. It actually kind of looks like the coolant temp sensor plug, which would be rather convenient for you. I'm not sure how it'd have gotten that far over though.

I don't happen to have my car with me at the moment, so I can't go look to try to find an equivalent plug.

[Syes200]

Actually I dug into the wire harness and found the temp. gauge plug, the idiot who had it befor me cut it off. The fuel injection temp. plug is still intact and plugged in. I can try to get a better picture but all I have is the camera on my phone. I've followed the wiring and it runs from the passenger side of the engine bay over the radiator and into the relay boxes by the battery. I've also got the car started and was pressing the pedal to the floor, it wouldn't do much until about half a minute had passed and then revved up but once I left off the gas it just fell on its face. Do you think that it may be the fuel pump?

[nametakennow]

Fuel pump maybe, but it sounds more like a backwards or blown MAF, as a fuel pump issue would probably keep you from starting altogether. From that fuzzy picture, I was kind of wondering if it was the MAF plug, it's in about the right spot, but I figured that'd be pretty much first thing to think of needing to plug in.

[Syes200]

That plug is on the other side of the engine. I tried to clean out the MAF sensor and I guess that helped it a bit. It could be a weak fuel pump, I've seen it on my friends truck, but I really hope it's not. I'll try to get a better picture today after work.

[Syes200]

Okay here's another picture. The plug is laying below the wiper motor on the passenger side. I've tried to find picture of this engine online but I haven't succeded yet.

[nametakennow]

I'm at a loss. There are several plugs that resemble that one. All I can say is that there has to be something in the area that's not plugged in.

Are you getting any Service Engine Soon lights/codes? Your car is OBDI, but I figure something might show up.

[RED_DET]

Probably the AIC valve.

[Syes200]

Actually the car is OBDII and I've thought about the AIC valve. As for the plug I don't know, the car seems to run without it but I would like to know what it goes to.

[nametakennow]

Doh! 200SX, OBDII, for some reason I got this confused with an early '90s Sentra someone was having problems with.

Just keep checking around that area, grab the plug and pull it to find the radius of where it could go and start checking places from there.

[Syes200]

I took a code reader from work and decided to check the computer, turns out my MAF sensor is bad. I think it's because of my K & N air filter but I'm not too sure. I've followed that plug and it goes from the passenger side strut housing, goes around the radiator, through the relay boxes by the battery, and into the firewall. It's gotta be something of importance but I just can't find another 200sx like mine. I mean I've found other ones but the base model doesn't have a plug like that on it.

[skeluhtor]

i have prob 10 loose plugs like that in my engine bay but i have the total barebones setup yeah its basically an engine on a wheel barrel with a seat, no power stearing, no abs, no ac, i just figure eh it runs fine must just be extra connects for stuff i dont have

[nametakennow]

I doubt your K&N caused MAF failure unless it's torn. Is it just a drop in or a cone? If you've added a cone to your MAF (or a CAI), not having a vibe mount can kill MAFs.

[Syes200]

It was just a drop in but I took it out anyway and it actually helped it, don't know how. Also found a tarantula by my driver side wheel as I was jacking it up cause for some odd reason the driver side CV axle won't stay in. I found out that the plug that is just laying there is for some kind of switch that comes off of my thermostat housing, the only problem is, is that this motor doesn't have that switch, I found it while I was thumbing through my book.

[Syes200]

Okay now I've got an issue. I took it for a test drive and the CV axle on the driver side came out while I was driving it. Any ideas on why that would happen?

[nametakennow]

Well, you had a problem with it not quite being in completely a week ago, so my first guess would be that it's not secured.

[Syes200]

No, I got it locked into place. I just got it all washed too. Think the ring might have gotten messed upped and won't lock it.

[nametakennow]

That'd be a good guess, that some sort of fitting was damaged in the previous install attempt.

[Syes200]

Okay, got another one in and it still does the same thing. You don't think that it might be that my differential is messed up do ya?

[nametakennow]

At this point, it's kind of beyond me. Check the last link in my sig and download your FSM (or check yours if you already have one) and see what it says about the halfshaft assembly and differential.

I suppose it's possible that something on that side of the differential was damaged either from your partial cv install or some other factor, most likely the former.

[Syes200]

well took the transmission down.......again, and it seems fine I felt inside the diff area and nothing seems to have been harmed. I did find that cv seal on the passenger side was gone, I have no idea how it turned up missing and my starter had died with it so I just love this car right now. I bought a new seal and happened to have a spare starter from the original motor that I know works so I'm gonna put that one on and hope for the best. Oh the FSM didn't help me, it says the same thing my little repair manual says.
