When removing my motor I found that the CAS was not connected. I called the guy that sold it to me and he said it hadn't been connected for a while. My question is, wouldn't the car be unable to run with the CAS not being hooked up?? What, if any, damage could have been done with this not hooked up?? The car ran like a dream with it unhooked. Just a little confused. Any help would be greatly appreciated. :thumb:
 
Take off the top of the timing belt cover. Check and see if there is a large disc attached to the intake cam gear. This would be the 95-96 style CAS. That was the case when I bought my 98 GST. It had a 96 ecu/motor in there, but had the 97+ style CAS as well. Either way, I would not worry about it, you are fine.

--Edit: I did not see that it was the crank angle sensor you were talking about. Whatever, I still wouldnt worry.--
 
I'm not sure if you are refering to the crank angle sensor or the cam angle sensor but it really doesn't make much difference. The car will not start without both of these sensors connected. Has any modifications been done to the car like a 6-bolt swap?

I am talking about the CRANK angle sensor. Hence the title of thread. Anyway, the harness for the crank sensor has been unhooked and it ran fine. Haven't had any six bolts swaps. The guy I bought it from is a good friend so I am very familiar with the car's history. Everyone keeps telling me that my car won't run with this sensor unhooked, but it did.
 
The crank angle sensor is required by the ECU before it can will generate the output to ignition transistor. So it must be hooked up. There are a few othe connectors on the back of the engine that could be unhooked and the car would run these include the knock sensor and the A/C compressor. Maybe it's one of those.

I am 100% sure that it is the harness for the crank sensor. I was pulling out the engine when I noticed it was unhooked. When I got the engine out I followed the wires that cam from the harness and they went straight to the sensor. I was dumbfounded. I have to say that this beats all I have ever seen. Maybe I shouldn't hook it back up when I put the engine back in. What you you all think?
 
Nobody is lying to you. The car will not run without a crank signal. The only possible way that your car would run with the crank angle sensor unplugged is if someone swapped in a 1g cam angle sensor.
 
I understand that it isn't supposed to run. But it does DAMN IT!!!!. Quit telling me that it is something else unhooked when it isn't. I'm not an idiot and I know it is the crank sensor. Now with that said, why would it continue to run?? Do I have some kind of freak or what??

Unless your car has a 1g style cam angle sensor providing the signal for both the crank and cam sensors, then I don't know what to tell you.

Don't bother replying to this thread anymore. We told him it will not run, yet he is convinced that it will.

This is the same as telling us your car runs without the ECU pluged in or was running without gasoline etc.... Can not happen.

Look man I am not saying that it will run, I'm saying that it DOES run. I don't need you telling me that it won't run. I asked for reasons as why is does run. I got one person to give a possibility into why. Everyone else was too busy telling me I was wrong. Thanks to the guy who helped.
 
Okay. You said that you followed the wires, right? Where did you start? I know you mentioned that you followed wires to the harness, but which harness? And you also mentioned that you saw they went to the sensor. Where was this sensor located?
 
Do you have a circle thing sticking out on the left side of the head towards the back? You must have a 1g cas.
 
maybe it was plugged in, but when you started to take out the motor it was accidentally pulled out without your knowledge. Then you look at it and say "how did it run with that unplugged?"
Did you work on it with a friend? maybe he unplugged it when you weren't looking, or they unplugged it by accident?

Was the car accually running at the same exact time your were looking at the unconnected sensor on the block?
