Is this a tune problem?

I just got my ECU back from Enthalpy. Installed my 550s and the MAF but the car doesn't want to start.

-Got fuel, you can hear the injectors
-Got spark, buddy flew back a few feet
-Test the MAF voltages and everything is good

Is this a ECU problem? What else should I check?

Is the MAFS the same as what the ECU was programed for?

Yep....It is tuned for my set up.

Just talked to Enthalpy, he says the 2.5v is way off and should be around .5v. So MAF problem? I'm thinking about getting a brand new ISIS MAF instead of a used one, has anyone used this?

With the car off and key on:

12v+ was 13.5

0-5v was 2.5
