She RAN!
 
If anybody remembers my electrical demon thread, I found the answer today. Turns out, on the fuse box, I had grounded the power wire. And was overlooking it because it looks like the right location. My bust ... But the car started up almost instantly, and ran for like 3 minutes. Then it just cut. Didn't stumble and die. Just turned off, as if I had cut the ignition.

I couldn't figure it out to save my life, but 3 hours later. I think I have a theory. After doing some more searching on the wiring. I found that I had the powersteering pump electrical line, unplugged, and the knock sensor plugged in where it should be. So I switched those out. But now ... I can't find the connector for the knock sensor. The illistration in the factory service manual leaves much to be desired. My personal pictures, amazingly, didn't capture the knock sensor.I know its the knock sensor, because I grounded the ten/gnd and get 5 short flashes. Which, when looked up, is Knock sensor. I then hooked up my PFS Purple, to see if it read the same code. It doesn't, it reads spark input failure. So my thinking is this:
The stock ecu is reading the lack of the knock sensor and is cutting ignition, making the PFS say there is a spark input problem (code 0100). Is this feasable? Can anybody show me a picture of the knocksensor hooked up, so I have some idea where to look for the connection on the wiring harness? Is it hidden under the UIM?

Oh, and thanks for all of your replys to my earlier problem. As it turns out, you were all right, the relays were bad. All of them. Lol, they were getting no juice. Also, there was a ground problem ... too many of them.

Anyway, thanks for any replys.

Your knock sensor plug is in the same harness as the Alt. and timing sensor plugs. Look at the bottom of your oil filler pipe, should be around there close to the front rotor housing.

Thanks, I will def. check that out in the morning.

The car will throw a code if the knock sensor isn't plugged in, but it should run just fine with it not plugged in.

Still couldn't find it. But I got it started again. The plugs are fouled out. Ordering some new ones. Anybody have a picture that actually shows it?

You don't need a picture...It's the same as the power steering sensor plug....Keep looking it's there, Or you may have broken off the plug.

I know its the same, because I thought I had lost the power steering connector. Then did some double checking on some pics I shot after the engine was pulled but not disassembled. Relized my mistake, but now ... the power steering pump is all good, but the knock sensor has no home. Worse comes to worse, this weekend I'll just pull the wire out of the ecu harness, and re-run it.

I'm also losing coolant now. Not enough to overheat, and not quickly. Takes a few hours. The strange thing is, there hasn't been a puddle under my car yet. I'm still trying to figure this one out. More in the afternoon. I work nights, so now at 6:30 I've been working since 3pm yesterday TOO LONG.
