3sgte engine in car. now wont start! Options

[toyotacrazy]

I started my swap last night! Got the engine out and the 3sgte mounted onto the 5s-fe trans. within about 4 hours. The motor mount next to the timing cover had to be modified to fit correctly. Ive heard before its a direct fit for the 5s-fe motor mounts. Its not! Only one bolt lines up without modifications. I took the mount to the grinding wheel and managed to make it fit well. If anybody wants pics give me your e-mail and Ill send you some pics of the mount. Hope this will better prepare some of the future swappers! later-

actually its pretty common knowledge that the passenger side mount has to be modified if you use 5s-fe mounts. But who researches these days anyway? Pics of progress? What year 3S?

take off your motor mount bracket from your 5sfe, and bolt it to the 3sgte. this way all bolts will line up correctly.

Its a 95 gt celica body and a 1991 celica alltrac engine with the gt transmission. I ended up using the 5s-fe mount that attatches to the engine. I spent about 20 minutes grinding it away. I did a TON of researching but I was under the impression that the gt motor mounts was a direct fit, and the st celica mounts had to be modified. Oh well, I figured it out. Ill put a pic of the mount on my profile. I dont know how to link my pics to this site any other way. They are on my computer. I can e-mail them though. Well back out to the cold garage. Later............

use www.imageshack.us, upload it there. after you host it, copy the "direct link to image" url. click the "insert image" button (the tree) when posting and paste the image url you just copied when prompted. preview your post to make sure it worked. hope that helps.

I got the swap all put together. It wont start! The ecm has code 12 no NE signal. I did some checks, Any Ideas? Thanks

Recheck ALL plugs. Almost everyone that does a swap has one plug unplugged on the first turn of the key. In this case, its one of the signals from the distributor that is missing. Good luck!

who did your harness?

I did the harness. There 12 volts going to the fuel injector resistor, and no power going to the igniter or coil. But when I put direct power to the coil + it still wont start. I'll have to cut into the harness more tonight.

No NE signal? whats NE.
mine threw a few codes when i had just dropped it in. Does it crank over at all?

give us some more symptomes of what it does when you try to start etc.

mine would crank but never fire... ( i had two plugs in the wrong spot on the harness)

It cranks over fine. The ne or g signal communicates from the distributor to the ecm. I have no power to the coil or ignitor but have b+ to the fuel injhector resistor.

[jcbass7]

are you getting a code for your engine coolant temp? or is that fine?

[toyotacrazy]

nope, just the code 12 = ne or g signal from distributor

[hitcachi]

who did your wiring?

[Defgeph]

I merged all your topics.
Please keep all you questions about your swap in this thread. We can help you better if all your questions are in one thread and not scattered in the FI forum.

Since you did your own harness what sources, diagrams did you use to get the wiring done ? Maybe something you used was outdated with old information ?

[toyotacrazy]

I got the ewd from the tis (toyota/information/system) at work. It should be up to date as anywhere else. Im thinking that I maybe put two wires together temperarily and forgot to solder them. Maybe they came apart. I checked all the wires for continuity several times. I am not getting any power to the coil or the igniter. I also took the distributor cap off and found quite a bit of corrosion. The rotor button has some small cracks in it. I ordered these today. Ill probably tear into the harness after work. Thanks!

[lagos]

the coil and igniter get their power from a thick black/orange wire that gets spliced into our fuse box. track that down, and make sure you hooked it up right.

[Dr_Tweak]

How did you do the wiring and which ECU are you using?

-Doc

[toyotacrazy]

Im using a gen. 2 ecu from a 91 celica all trac jdm.
With the wiring, I started by taking a junk yard fuse block from a 95 celica and marked all the wires. Then I split open the 3sgte harness and found what everything was and marked it. Then I just figured out what the engine needs to run and hooked them together. All my gauges seem to work fine.
It cranks over and I can smell fuel. I did however find out that the coil and igniter werent recieving and power, but the fuel injector resistor had 12 volts. So I tore into the harness until I found the problem. I forgot to connect the thick wire black/orange to the coil and igniter. So I did this and made sure I now have power to both. I carefully connected everything back up. I tried to start it but still it acts like it has no spark. It doesnt even try to start. Ive got a distributor cap and rotor comming tomorrow from toyota. I doubt this will fix it, but the button and cap looked pretty crappy when I took them out. The rotor had some small cracks in it. I still have the code 12 for the NE or G signal to the distributor. I hope this all makes sense to someone. This is so frustrating! Thanks guys!

I don't mean to just throw in a question here and ruin the flow but so it is possible to throw in a 3sgte onto a 5sfe tranny? It can handle it well, or not optimal? Second, what was done to use only the front transmission, do you block off the axle that controls the rear wheels because of the front wheel drive tranny?
