Rough idle/No Start
I'm at a loss for where to go next on my car. Car was running fine a few days ago. Pulled in the garage with no issues and nothing out of the ordinary. Now the car won't start. If it does start, it sputters and shuts off. A good bit of fuel smoke dumps out of the back of it. Pulled the active codes on my DIC. Only one is P0108 C. I know this is the MAP sensor. I replaced it. Checked my vacuum lines. Car still won't start. Same issue. Pulled both valve covers and checked my springs. All are there and intact. Car has full exhaust, catted x pipe, no rear 02's, milled 243's and a cam. Everything seems correct. Anyone had any experience with this issue? I'm off work all week so I'd like to drive the dang thing.

HOW are you reading the DTCs???
What do you mean wont start?? Wont CRANK or Cranks but wont fire??
Can you clear that DTC??

I ran the codes with the DIC. I did not clear them. The map sensor code is current. When I say it doesn't start, I mean it turns over for a while. Fuel is there. Generally won't fire. If it does fire, it runs extremely rough for a very short amount of time before it stalls completely out.

All cleared. Repulled after failed attempt to start the car. Same code as previously posted.
P0108 C
This is the only current code.
"Them" referring to history codes on the traction control that were also in there.

I got it sorted out. I suppose a lot of my confusion was the tune. The car didn't set any other codes. It ended up being the MAF. I unplugged it and all of issues went away. The car still hasn't given me a code for the MAF but has cleared the MAP code after three engine cycles. I suppose this is what I get for buying an already modded car.
