Question about 2007 Pontiac G6 GT Convertible
Replaced fuel pump no fuel pressure. Car ran but now won't crank no fuel pressure
Make sure theres juice going to the pump. You should here the pump running when you turn the key on. If theres no juice check the fuse.

Did you check the fuel pressure at the fuel rail? with key in the on position to activate the pump? If you did and there was no pressure I would first check for the obvious, gas in the tank, leaking fuel from a line, check for flow before the fuel filter, located at the rear of the vehicle near the gas tank. take the fuel pressure line off put it in a catch can and have somebody turn the key to the on position to activate the pump, if it flows chances are the filter is plugged. Also pay attention to the sound of the pump if it is very loud there is a good chance the pump is failing and needs to be replaced. It could also explain why sometimes it dies. The pump is going out of range. Hope this helps

Sounds like air in fuel line. Purge fuel line. By "crank", do you mean engine spins but won't catch? Try starter fluid in intake.
