Or the pump is no longer pumping even though the pump is humming it may not be pumping I realize this sounds like a stupid question but do you have gas in it.

ok well i lost complete fuel pressure, replaced the whole pump assembly(yes sending unit and all) relay kicks new pump kicks and has fuel going to injector spraying a erfect downward jet.....still same issue, but it is getting to where it wants to run, still have to floor it to get it to start for a second (when i say second you cannot get one onethousand out before it dies) before when i didnt press the gas it dodnt want to start but now it sounds like it wants to start but still have to floor it to get it to start. tps is good so is map all vacuum lines are good timing as far as i can see is set....................someone please have something

Stupid question, I'm sure, but I'll ask it anyway. When's the last time you cleaned the throttle body?

I out of ideas except spark plugs and wires but that would be a long shot to have them all go bad at once

Remove the valve cover and watch the operation of the valves. Make sure they are opening enough, but if the compression is good, then they probably are, but I'd check. Last thing has to be timing. Yours is a lost spark ignition isn't it (two coils).

Did you check for spark on all four plugs?

I am back to timing I agree with Keith pull the rocker arm cover and check and make sure the valves look to be opening up and check the timing at the same time check a repair manual and make sure the timing marks all line up
