Grand am not getting fuel

[05GXPBeast]

I have a 2003 grand am that will not start. I first replaced all 4 spark plugs. Then I replaced the crank position sensor. When that didn't work I decided to change the fuel pump. The new pump works, and it has pressure at the rail but it won't start still. It fires for half a second when you first try to start it, but after that it won't fire again unless it sits for a while. But it will run if you spray starting fluid into the intake, but dies when the starting fluid runs out. What am I missing here?

I should also mention it's the 2.2l ecotec 4cyl.

All the injectors show 11-12 ohms for all four. All the fuses look good. I'm stumped

Turned out to be the passlock sensor. I let the car sit with the ignition on and it started after 10 minutes or so.

Interesting how did you figure that out?

The start then die right away kinda gave it away for me, the security system will make the car do that if tripped.

It's not always the case but somewhat common.

I noticed the security light was flashing When I turned the key on, and after about 10 minutes it wasn't flashing anymore. Then it fired tight up. I'm suprised it took me so long to notice.

I sell a fix for that! Happened to me in my impala for a year before it was too often.
