All fuse good. Spark good. No gas pressure. RPM gauge move when trying to start. Can someone confirm CPS is good? Anything I can try before buying fuel pump.

If you have measured fuel pressure with a fuel pressure gauge & there is no pressure, then its the fuel pump & or fuel filter.
If the RPM gauge moves while cranking, it indicates that CKP is ok.

Thank you for the fast response art_arev! No other sensor that is stopping fuel?

on a 2005 model, I am not sure which is the relay & the fuse for the pump. Open the footwell fusebox & check if the fuses are ok. Check in the engine compartment fusebox if K3 relay is for fuel pump. If it is replace with a similar one from the fusebox.
Inspite of RPM gauge moving while cranking, the only 1000% way to know that CKP is ok , is to scan the car.
But, still, the fact that there is no fuel pressure points at a fuel delivery issue (pump/filter).

Thank you, Thank you. Didn't know there was a 2nd fuse box.
