Hesitating to Start

[Paintball0027]

I have a 1999 grand prix GT with about 212k miles on it.

I was driving it the week before christmas and it was working fine. Let it sit for about a week or a little more (I live in Michigan, it was cold and we had a very bad ice storm while I was gone).

When I came back, I went to start it and the battery was completely dead. So I let it sit on the charger until the battery was charged and tried to start it again. It just sat there and turned over. I tried countless times to start it and it would just turn over. So I tried to jump it, thinking the battery wasn't giving it enough juice to start. This didn't work either. So I figured it wasn't getting fuel.

Turned the key, and heard the fuel pump turn on. So I knew this was a good sign. Thought maybe the fuel filter was clogged or bad. So I swapped that out and it didn't help either.

Anyone know what could be going on? I was told maybe condensation in the gas tank?

Thank you.

Unplug the MAF and try again.

And you could pull the fuel line off the FPR to see if fuel comes out and that would say that your regulator is shot.

I've unplugged the MAF plenty of times. Replaced it like two times in the past couple years. I believe that the wiring is messed up on it or something because I've bought a brand new MAF and it still didn't run as good as it does unplugged.

But right now, unplugged/plugged does nothing different.

So unplug that vacuum line and try cranking it? Or just unplug the vac line and see whats there?

Thanks.
