How old is your battery? It is not enough to charge it if it is old. I've read about modern accumulators or supercapacitors https://supercaptech.com/battery-vs-supercapacitor/ and they say that the latter can be much more reliable sources of energy.

If it's not a battery, then check the starter, maybe the whole problem is hidden in it.

This may sound crazy but did you check the gas cap. My sister spent almost 800 dollars trying to fix a fuel problem only to find out that the fuel cap was broken(did not seal properly).apparently the fuel system is pressurized and needs the cap to make the tank a sealed unit for the pump to work properly.I know it sounds crazy but after they replaced a 25 dollar gas cap the car ran perfect.

I was just going to say that you are getting air in there from somewhere, follow the lines also and see if there isn't a hole in the line somewhere, or a leaky gasket.

Tamarind: I was thinking cabriolet(convertible).i have never heard of a caddy. I am thinking a van/wagon could be another one also. They have some wierd local names for cars. I thought i would give it a shot.
