Car won't fire up
 

Yesterday around 4 PM after having the car had sat for a couple hours the car would come close to starting up but doesn't fully fire up. After continuously trying it several times and pumping the gas when doing it, it worked.

Around 9 PM car had sat for about an hr and same thing. Wouldn't work at all. Decided to jump it, wasn't working and with some pumping of the gas it finally worked. Gas was low, filled it to half tank.

Around 12 AM car sat for about 30 mins to an hour and it started it up just fine.

Around 2 AM the car had sat for about an hour. Doing the same thing, wouldn't work. Tried jumping again, wouldn't work. Left the car in the parking lot since it was too low to tow and in the morning tried it again, didn't work, but didn't try jumping it. Ended up getting it towed.

Anyone have any idea what this may sound like? All I have is an intake. I cleaned the filter several weeks ago. I recently got a TSB done the day before at dealer (passenger air bag), and I've never faced this issue at all till yesterday.

*EDIT: Just got word from my mechanic that the vehicle is throwing a P1610 code, which states it is a NATS Malfunction. Do any wires run underneath the car, ground or whatnot that go to the ECM or BCM where if I bottomed out the car near the sway bar, power steering, and cats it could damage them?

does the starting of it sound off? like..slow?

It seems normal. There's a certain noise I'm supposed to hear that I don't. Like when turning into the ACC position. Dunno if its fuel or the throttle body moving, but it's not doing that.

You're supposed to hear the fuel pump. Put it into ACC until you hear it then crank it.

First thing i would check is fuel pressure.

You're fuel pump has gone bad and will need to be replaced.
