Default will not start when hot

Hi,

I have an 84 with Crossfire injection and I'm having problems with it being too lean when hot. I have to remove one of the air cleaner nuts and spray some carb cleaner to get it going. It isn't an every time problem but is becoming more frequent. Will changing the computer temp sensor correct this problem? Is there a circuit that richens up on starting that isn't working? I have rebuilt one of the throttle bodies and replaced the fuel pump. I will probably rebuild the other and bump the pressure up to 15 PSI at the same time. Should I be able to hear the fuel pump run when I turn the key to on?

Can anyone help me?
