more info please
what was done between the time it last started and the time it didn't start?
Will it at least crank?
Have you tested to see if you have spark?
do you have fuel?
Most important though... my first question... what changed from when it did start to when it didnt' start

i have fuel, it smells like raw fuel when i try to crank it
it sounds like it wants to turn on but it backfires and then dies

ok... you're getting codes for the MAF and the MAP
check the MAP sensor in back of the INtake Manifold... make sure it's securely connected (sounds simple.. but when i did heads and cam in 2003 I forgot to hook the MAP sensor up)
the MAF code is strange though.. P0102 would cause the car to run in Speed Density.. which on a car not tuned to run in that mode ... it'll fire up.. but then die unless you give it gas
make sure there are no wires pinched between the block and heads and between the block and intake manifold

I think the thing we need to concentrate on is the P0102 code ... this will definetly put hte car into Speed Density mode... which on cars not tuned for it .. will make them run like ****
Check the Eng Ctrl fuse (i think) ... earlier this year I had a problem where my O2 sensor wiring was hitting the header... would blow the fuse and would force my car into Speed Density... car ran like ***! (this was before I did a SD only tune)
the P0108 and P0102 together I don't know about (don't know under what conditions they'd set at once) but P0102 ... check the eng fuses under the hood...
I'm about to venture outside in the snow for another post... I'll check what fuse name this is for ya too
