No problem, chad...glad you got the cam timing figured out...
I highly doubt its specifically fuel related now...chemical properties of gasoline do allow it to absorb moisture, as well as 'gum' up over time...but with normal fuel injection systems, it'll take longer than just a year or so for that to become a major problem...especially considering the climate of where you live (its not nearly as humid constantly, like other parts of the country)...This commonly messes up smaller engines, that require very little fuel per cycle (a lawnmower, for example)...but a fuel system of a modern car with considerable pressure inside the fuel system...will usually have little trouble blowing all that gummed gasoline right through...despite a lot of myths about it...
One thing to try, first...is relieve the fuel pressure...you can do this 2 ways...the 'real' way is to remove the fuel pump relay in the engine bay fuse box..I forget which specific relay it is, but this link below should help...Some members have had trouble with this method, as removing the relay just caused their car to never start (and in which case its not removing the pressure)...so if that is the case, just pull the electrical plug on top of the fuel sending unit, under the rear seats...
try to start it by using either of those methods...it should turn over fine, hopefully start for a few seconds...then completely stall...that'll at least move the fuel around in there without sending more to the engine...then reconnect everything and start it again...it'll have to crank a few seconds longer before fuel reaches the engine...If still no start...it is most likely the pump...if it starts, but continues to have trouble...it may then be the fuel, or something ignition related...
What coils are you using, and how old are they? You should be using MSP plugs, wires, and coils... not whatever came with your 'new' engine...lots of changes to electronic ignition happened to these engines over a pretty brief time period...so try to use whatever parts your MSP ecu is used to seeing...check your plugs, and replace if necessary...as well as the wires...
lastly...any codes? and positive of no vacuum leaks? its VERY common for a slew of vacuum leaks to show up with a new engine install...intake manifold gaskets are very tricky to seat properly before a few heating cycles...did you install the IM with the engine out? that is far easier to get the gasket seated properly, but very easy to bump the entire IM during installation, which can distort the seal...causing a vacuum leak outside of the normal vacuum lines...
also i'd check all of the intake plumbing...did you replace hot and cold MSP pipes (i'm sorry if you've listed this, i just started typing haha)? Those are notorious for drying out...as well as the 'accordion' pipe running to the TB...if all that has just been sitting around in dry air for a year or so, its possible they are not sealing properly...for the most part, you should be concerned with plumbing behind (engine side) the MAF, as your car seems to be behaving like it has a major condition of ummetered air entering the engine...
You can try some water treatment in the fuel tank if you're really worried about it...but coming from all this occuring from a new engine being installed...i'm fairly sure its something not quite as simple...but who knows, maybe you'll luck out and just need some new gas...
