You can get stored codes that can give you a clue as to the problem, so running a KOEO test to get any stored codes is worth the effort. Also, let's just make sure - the CEL should come on when you start the car, just for a little bit. It's a safety feature to show that the CEL is still working.

You might want to check the wiring that leads to the MAF. Maybe you plugged it all back together, but the connector didn't actually click together all the way? It could have worked its way loose. Follow the MAF wiring back to the sheetmetal, there should be a connector that joins the MAF & ACT wiring to the main harness.
