ok heres the deal....
went to start the Lumina after a particulary cold night(not sure if that has anythin to do with it?) and its a no go....started to go down the list..fuel..fire..ect. come to find out that the fuel filter was clogged so i replaced it and notta. pulled the filter off at nut end and turned key and sure enough fuel everywhere..lol..ok fuel pump works but not sure if im getting enough pressure to the rails.when i crank it for a bit it smells of fuel in the engine area. i checked the plugs and am getting good spark from the front 3 plugs...3 rear plugs of course take an act of Congress to just get to but i dont believe(defitnitly could be wrong)that its a problem with the plugs. It seems like it "wants" to start but just cant get it done. I've read about 1500 of the post tonight until my brain is numb (didnt take long) and there seems to be a trend of the fuel pressure too low...the fuel pump itself...the fuel pump relay...or mabey bad injectors. but one of the little voices in my head keeps telling me its a timing issue but then again i just replaced the fuel filter...soooo...now im confused lol. I'm not independently wealthy so im prolly gonna have to do this myself so any suggestions would be greatly appreciated.

Thanx ;-)

Even though it shouldn't happen, sometimes even a fuel injected motor will start to flood in extremely cold temps, if other conditions (worn plugs, low battery, weak spark) exist. When this happens, just like with a carbed model, the only cure is to dry the plugs. If you hold the throttle wide open while cranking, it may start. If it seems to be trying harder to start when you do this, turn the key off, block the throttle wide open (to allow the cylinders to dry out.) and try again after half an hour. The fact that you said you smell fuel in the engine compartment leads me to think this is your problem.

If not, hit it with some ether through the airbox. If it starts on that, then dies, your fuel pressure is not high enough for some reason.

hey jeffcoslacker,
thanx for the quick reply and i just tried the throttle wide open and same result but i will pick up some ether on the way home from dr appointment. I have WD-40 here and was told that might work but i think ill pick some up ether up since it is designed for that purpose and not to loosen nuts and stuff lol. again thanx for the quick responce and ill keep ya updated.

Some motors will try to run on WD-40 (2 stroke engines LOVE it), but yeah, ether would be better.
