quest+AEM+fuel+spark = no start. help?

Does it fire in the slightest? If you are getting spark at all, then the CAS and AEM are atleast getting something, but it could be firing the cylinders on the wrong stroke.

Are the spark plugs soaking in fuel or not?

Did you adjust the fuel and timing maps for the MAP sensor change, they need to be rescaled, but wouldn't be used until it fires and gets out of cranking mode.

Cranking timing is usually in the 10-20 degree range.

Do you adjust the cranking fuel table?

The main fuel and cranking fuel table would also need adjustment for the displacement different between a 2.0l and 2.6l.

Are you using a CAS, ignitor and coil from a 1G or are they setup exactly the same on a Conquest, including the way the CAS is orientated into the cam?

No fire at all, just cranking. I didn't check the plugs, not a whole lot of time that day.

I just changed the sensors and fuel injector size in through the menus. I did not mess with any tables. This was my first time seeing the AEM program running, and I've never had any training/experience in tuning, so I am a n00b.

It uses everything from a '90 dsm. I modded the camshaft to drive the CAS from the back - see "turning my quest into a dsm" in the project section on this site for pics.

I will try some of the stuff you (extremely helpful) guys are suggesting, but with every response I am leaning more and more toward just bringing it in somewhere.

If you haven't read the manual yet you will need to if you want to have a chance. But your best bet maybe to bring it to somewere that has some experince with them. If you've done your work right, it shouldn't take long to get it going.
