Here is my situation. I have been working on swapping a 6-bolt motor into my car over the past several months. Today I finally got everything hooked all back up correctly(I think). I have a AEM EMS which had never given me problem before, but the O2 voltage is at 2.50 and won't go any higher. Berfore the swap the voltage was higher I'm pretty sure. I double checked the timing on the crank as well as the position of the 1g CAS before I installed those parts. I have the plugs swaped and the injectors how they came from the factory. My friend that I was working on this with thought that the timing must be off so we fiddled with the 1g CAS in attempt to get things in spec so that the engine would fire. How it is now the CAS is rotated as far to the right as it can. I am not sure what kind of a relation this is to timing so if someone could let me know that would be great. MAP sensor is reading -.56PSI so that seems to be about right. AIT temps are at 90degrees where I am.
Now here is what happens when you try and turn the car on. It will crank over and kind of sound like it is almost starting but isn't able to catch itself if that makes any sense. I actually thought that it was going to start a few times, but it never did. The first two times that we tried it the engine backfired if that help you guys any. If I remember correctly I have my crank advance set at 17 degrees, crank injector pulse at around 45, and the 1g cas adjusted all the way to the front side of the engine. If any of you want to see the cal that I am running on the EMS let me know and I'll email it to you. Any help would be appreciated as I am at a loss for what to try next. I was really hoping that this would just fire the first time I turned the key. :cry:

I now have no spark. Would putting in NGK BP7ES plugs how they come from the store .5 and not gapping then to around .28 cause there to be no more spark? I messed around with the cal file and really am stuck now. Thinking that I might have to give in and take it to someone to look at when I actually have money again.
 
Not really buming the thread but....

I was talking to some people and we all agree that the timing on my car is off, but we are not sure if it is getting too much or too little. I guess that either way is not really good. I am almost 100%, like 99.3%, that the timing belt is on right. The question I have now is how far can you adjust the timing with a 1g CAS? Right now I have the CAS cranked all the way over to the front side of the engine bay. Should I center it again and try and work from there. That is how I had it initially and I was getting no start then so I moved it. I think I'll give myself a few more weeks of researching my problem for pssible solutions before I start calling around to the local tuning shops. :notgood:
 
There are a couple things that could be wrong with the wiring. Some 2G connectors don't get used, and you have to get a jumper connector for the CAS.
Also, make sure you swapped the plug wires. 1 for 3 and 2 for 4.
 
I got the wiring harness from RRE to use for my CAS. Now, as for swapping the wires. You don't have to switch the wires at the ECU, do you. I just switched them going from the Coil pack to the spark plugs. I tried to start it both with the plugs swaped and with them how they are stock. It didn't seem to do anything different either way.
