Is it cranking with no start? Have you checked your base fuel pressure?

Yes, and What is the base feul pressure and how do you check it?

An experienced technician with a good manual gauge will be able to check the fuel pressure. Figure low 40's in PSI.

is there a way we can get to the fuel tank thru the trunk of the car?

No, unfortunately, the fuel tank must be lowered from the vehicle.

the fuel pump is not sitting in the tank correctly or try changing the fuel filter under the rear driver door underneath the car near the frame
