hey, red and white, me too, anyway, is there weird smoke out the tailpipe?? CEL on?? rough idle, or no idle at all??
no idle, could be the obvious iac.......
and also, i'd recommend a cylinder leak-down test rather than a compression test, so you can pinpoint the exact location where you are losing pressure.........

leak in the fuel line? I didn't even know the injectors could pump that much fuel...

Also, check the MAF (mass air flow sensor). If you don't know, the MAF senses how much air is coming into the engine and it tells the computer how much fuel to use so that you will run with a good a/f ratio. If the MAF has gone bad, I wouldn't be the least bit surprised. I know for fact that an f*d up MAF will KILL your idle and that could be a reasonable explanation for your fuel loss.

You can get a MAF either from a Junk yard of from the classifieds section of this forum. I know that there are alot of engine parts for sale right now in the "for sale" section.
