2005 Chevy Cavalier won't start. I changed the crank sensor. Has no fuel
pressure at shrader valve pressure test port and engine just quit.

Answer:
Well, with no fuel pressure at the test port, you more than likely have a
bad fuel pump. Have you checked the fuses and relays?

Yes.

Ok, if they check good then you're going to have to drop the gas tank out
of the vehicle and replace the fuel pump assembly.

I'm getting a clicking sound coming from my throttle position sensor area?

That noise is the electronic throttle body, and is normal.

Any head's-up I should think about when I pull the tank.

It is a pretty straightforward repair. If you don't have a lift, you need to get
the car as high as possible. The tank has to kind of slide out on an angle
towards the right side of the car, to get it over the exhaust, etc.

Thanks 'Pal'.

No problem at all, glad to help!
