Thanks for reading. I need your help;
For christmas I bought my girlfriend a 97 sunfire gt with a 2.4 and a 4 speed auto.I didn't tell her and I'm trying to get it ready so I can put a big bow on it for christmas morning. Anyways the car has 100,000 miles and i went and saw it, pretty much mint, brand new tires RAN GREAT etc. Only problem is tranny is blown. Thats okay, i have more time then money. So I take it home for 400 dollars, and start. As I take the tranny out I figure out that the bolts between the torque converter and the flywheel broke. Soo after replacing the flywheel and torque converter the tranny is back in. Now everything is buttoned up, checked the grounds, previous mistake. Everything looked fine. Turned it to fire it up. Starts cranking, won't start, shut key off, keeps cranking damnit! Disconnected the battey, turns out I screwed up the wiring for the starter. After tracing things in the wiring I figured out I hooked up the ground for the relay to the post that tells the starter to start cranking darn. SO fix that, now it turns out it won't start. Pull the valve cover/ coil thing, no spark. So i either didnt hook something up or something is trying to mess with my mind. There is a connector near the starter, it is a two wire or pin connector that has a purple and yellow wire. This is not connected to anything, but I do not remember disconnecting it, and I can't find anything to connect it too. Two other possibilites. There is a connector right near the connector for the valve cover/ ignition pack thing that has a grey plug in it. Don't know what that does. And one more possibility, i was thinking that somehow i might of shorted the PCM by grounding the relay through that purple wire that comes out of the harness and goes to the relay. I don't think its that plausable but might of happened.

SO now i need j-body.org's help to get my girlfriends christmas present running so i can get it to inspection.
Whats a better present then a jbody?
I need more ideas.



Thank you very much for reading.

how big are the wires on that random plug? they might be the neutral saftey switch but that wouldnt let it crank at all

could be the crank sensor. If thats not plugged in, you wont get fuel/spark. Its located right by the oil filter, you can see it from under the car.

make sure that you put the grounds back on the bell housing bolts, I think there are at least 2 and will have ring terminals on the ends.

I dont think that grey plug goes to anything, I remember seeing and hearing about that mystery plug.

The 96 z24 i scrapped at the begining of the year didn't have no plug just hanging like you said. As to the only random plug you should have is the one that would go to egr. Not sure if 99 and up 2.4 harnesses are like this or not but i know the 2200's are. Is this plug you are talking about paul in the wire loom with the starter wires? If so that would be the crank sensor i believe i could double check. If this is not pluged in your injectors will not fire and you will not get spark. Like already said. I made this mistake when i did my 2.4 swap. You might be able to see/feel where it plugs in by going under the manifold.

Paul did the car even run to begin with? Since you said you don't rember unhooking anything. Also make sure the fuel pump is kicking on. If not check your fuses. And i'm also curious as to how in the world the car cranked over with you having the ground wire for the starter relay hooked up to the starter with the signal wire. It should have did anything besides probably messing up the relay or possibly more.

There should be a total of 4 wires grounded to the tranny. The battery ground, 2 big ring terminals(know for sure one wire to one of them is tan) and the starter relay ground. On another note though did you by any chance touch the starter wires together or anything with the battery hooked up still? I have seen this fry computers on other vehicles never on a cav/fire though. You hooking the relay up wrong might have did it also

OOO I think this might we it. But seriously I was searching everywhere and couldn't see anything that it could plug into. But it is right by the oil filter and i was finagling the starter out right there. I will check tonight.
The wires are about 16 gauge. Look like the exact connector for the abs sensors.
All the grounds are hooked back up.
And to blown pheonix. Thanks for the reply. Very helpful. The car did run to begin with. Ran great. The fuel pump is kicking on and all fuses are good. I am guessing it is the crank sensor. I will have to wait till tonight.

thank you everyone. I will let you know how it goes tonight.

I looked up your engine wiring really quick and found 2 sensors that use both purple and yellow wires in them, one is the vehicle speed sensor on the transmission and the other is the crank sensor, both of the crank sensor wires go directly to the engine control module on top of the engine. they are pins F (yellow) and J (purple) of plug C1. Maybe try to trace them from the module and see if thery are the ones unplugged, also on the module pin L pink should be your ignition power feed for the module to the under hood fuse block IGN 20a,this feed is only for the module, nothing else and is switched with the ignition switch.. and pin K black is the ground G101 rt front of engine compartment engine computer and fuel pump relay also share that ground.

It is a auto. So the vss sensor will have more the 2 wires due to it being the 4 speed. 5speeds have the 2 wire vss sensor and as far as i know 2000 and up 5 speeds is the only purple and yellow.

Paul sound like to me you somehow unplugged the crank sensor. You car will crank and the pump prime but will not get any spark or fuel. In which like you said that it wasn't getting spark. Did you every get around to checking the sensor to see it if is plugged in?

Thanks for all the help guys! It was the crank sensor. It got unplugged when i was wiggling the starter out of that tight spot. Thanks for he help in getting my christmas present ready.

No problem, hope the G/F enjoys it.
