My 98 gt has been sitting for a month went to start it got a no fuel pump prime. So I replaced the entire assembly an filter still no prime . Checked fuses under the hood and Inertia switch. Still no start not flashing any theft light goes away as it should. I’m thinking it’s my ccrm but when I turn the key I do hear relays click. I’m not sure I’ve tried looking over everything any advice would be appreciated so much.

Check the details I gave in the thread below; should give you most of the details to check the fuel pump's power source from battery to pump. I would also see about renting a fuel pressure gauge and confirm you have no fuel.

V6 to V8 swap no crank, no fuel issue.

Camshaft or crankshaft position sensor being unplugged / bad would cause a no-start scenario, for sure.

98 being return, doesnt it have multiple relays for ccrm? Maybe just one of them went out.

Still just a single relay in the CCRM. It just has a pressure regulator that allows excess fuel to return, where the returnless cars have a controller for the fuel pump to control how much pressure is in the rail.
