1995 Ford Taurus hard starting/ no starting

I have a 95 taurus with a 3.0 that will not start. It didn't run for a good month and finally got it started after putting it in the garage. It ran fine for 3 days and won't start again. It has a new battery, good fuel pressure and good spark. I checked the signal to the injectors with a noid light and they seem to be getting a signal. I looked at a tsb for the year and engine and it said possibly the iac valve, but i checked the resistance and it checked out fine. I ran into a funny thing when i got it started. The only way to get it going was to pump the accelerator as fast as i could. Now i know that this only opens the throttle but its what worked. Need help
Thanks!
