Well im trying to get my car registered and have to get it in working order first. Im trying to get the fans re wired back to factory as they are completely hack jobed. I need to get the temp gage to work i replaced the temp sensor on the front of the block i hear theres one on the driver side head? Is there a common problem with the temp gauge? How do you test if the car is going into closed loop when warm?

 

Well i think i know what the problem is haha
This is the wire that should go to the temp sending unit on drivers side head i believe.


Heres the fans wiring now. Stock wires are still in tact for the most part but all new wiring put in place terribly.


Then under the dash is the after market key phob and alarm wiring mess...

 

Sensor at front of intake is the CTS (coolant temp sensor ) for the computer.
Temp gauge sender is in the head

What makes your fans run now ( or they don't ) ?
This is how your fans should be wired

So i fixed the temp gauge car is going into closed loop i believe and i have replaced a bunch of sensors trying to get the car not to die when you put it in gear could a bad TPS cause it to die in gear?

 

Have you pulled the engine error codes to see what problems you actually may have instead of guessing ?

 

Yes i have tried pulling codes and get a 12 i did get a code 22 but i already know its bad because i tested the ohms as i moved it and it had a spot that the ohms dropped. Thats why i was asking if it could be a cause.

 

So got the dieing in gear fixed with a new dizzy. Working on the fan wiring now and this seems odd to me what about you guys?

 

poor contacts on the connecter or to much amp draw

 

Hey again Tuned. Idk if the fan would draw that much power. That is pretty well melted lol. The fuse was bypassed for the relays though.

 

IIRC that's is the relay trigger side power from the orange wire. A 30 amp draw or more with no protection and a loose connection heck yeh **** will melt.

 

Haha true true. So am i best just snagging another connector from a v6 at pick n pull?

 

yes, If I remember correct gm started to use the relay weather pack connecters in 88. Most every gm vehicle used them for one application or another .
If the rest of the terminals look good I would just repin that one terminal solder and shrink tube or crimp weather proof butt connecter? The less wiring hacking you can do to salvage your harness the more reliable it is. Check the secondary fan relay the two wires are connected.

 

Looks like A and E are damaged, was hard to see earlier on my ipad
I bet someone had issues with the fuse blowing. There is a corrosion issue with the power or ground wire on that fan or
The fan is bad drawing to much current when its commanded on.

 

When i got the car the fans were wired with a switch not using any of the factory harness. A switch activates the relay sending power straight from the battery to the fans. Im trying to get it controlled by the computer again then ill reprogram the ecm so the fans come on at a bit lower of a temp.

 

Looks like what happened when I wired a hot switch to turn my fan on. Have since corrected it and made it a ground switch to the relay, and now an adjustable fan controller wired to the ground trigger. Hey we all gotta learn somehow, right? Thankfully I didnt light my car on fire..

Also looks like mine after the fan motor went bad, noplace for all that current to go.

 

Well thats good to know haha. Any chance you guys could tell me some reasons im getting a code 24?

 

High idle for too long or loss of vss signal.

 

Oh lol thanks tuned. I have no vss because the temporary trans in the car has the wrong style vss. The trans has the magnetic pick up style the Camaro had the gear driven style. They out put different signals. I want to put a manual in the car but money does not allow at the moment. I need to find factory Camaro rims.

 

Sounds like you need a Dakota digital sgi-5 or a drac. I'll sell you a set of 15s

 

Can you PM me a pic? And a price shipped to 96007?

 

What is a drac? Is there any other solutions that are not 90 bucks haha not a terrible price but better spent on other areas of the car.

 

Does having the vss unplugged decrease performance or fuel milage? Oh and when the torque converter locks up how much should the rpms drop? When the torque converter locks in my car the rpms barley change maby 2 or 300 rpms

 

A drac is used on trucks, it is a digital ration adapter controller. You would still need to do programing for the 730 ecm to accept a optical vss signal . Your tcc will not lockup without a vss signal. The ecm doesn't see the car moving, iac is also effected.
Gas mileage and performance is effected with the code 24 thrown.

Lmk if your interested and I will get a shipping quote

 

When i say the torque converter locking i mean by jumping the pins on the aldl with a switch.

 

That's different

 

Which part?

 

The re- engineered tcc lockup through pin f of the aldl

 

That should lock the tcc though right? It was a temparary thing i did an hour before work.

 

Ok so i just got the sgi-5 c from summit dose any one know what the output signal of the strans is and what the car needs like how many ppm the car should see?

 

4k ppm magnetic pulse to B10

 

Alright will do in the morning i cut the wire and connected it up to the sgi will wire up the ground and acc power tomorrow. Do i need the sesensor ground as well?

 

These speed sensors have a two-pin connector on the transmission or transfer case. One of the pins will be a ground and the other will be the signal. The ground pin will go to the GND terminal along with the ground wire. The signal pin will go to the SIG IN terminal. It is best to twist the signal and ground wires from the sensor around each other. This helps eliminate any electrical interference. If nothing else is connected to the speed sensor it does not matter which pin is used as the ground. Connect the PWR terminal to accessory power. The output connections will depend on your particular application.
You can read the instructions !

 

Alright cool thanks again tuned

 

This looks like a trick new option

Got the sgi-5 hooked up and working great it's a little off so I'll have to keep calibrating it till its spot on. Next project is a t56 tranny. The hard part is finding one haha. Will post add on the forums and craigslist...

 

If you you have a GPS that shows mph its a easy way to help with calibration.

 

Downloaded an app for the phone and got it calibrated in seconds. Pretty nice little gadget. Not sure if the t56 or the ebl should be first
