Welcome to 2carpros
One way to diagnose a broken timing chain is to pull the valve cover and watch the valves while the engine is cranked. No movement means the cam is not being driven.
(3.8 has timing chain)
You will need to properly relieve the fuel system pressure.
Disconnect the negative battery cable and drain the cooling system.
Remove the intake manifold with the throttle body.
Disconnect the coil wires, sending unit wire, heater hoses and bypass hose.
Remove the closed ventilation system, evaporation control system and cylinder head cover(s).
Clean all gasket mating surfaces
the fuel test port is located on the fuel rail
