Is there a blockage somewhere or fuel pump issues.. It has less tha 85k miles and when it runs it's great .. Help please
If fuel is not getting to the carburetor, then you have one of a few different problems. The most common would be the fuel filter being clogged. Depending on your engine you may have one or more fuel filters both external and in the carburetor. The next would be the fuel pick up tube screen in the fuel tank being clogged from debris in the fuel tank. This can be checked by seeing if there is fuel getting to the fuel pump on the engine or if it has the mechanical pump style. A fuel pressure test and volume test is needed to see if the fuel flow is blocked in the tank or the pump is weak and cannot pump. I would start by replacing all the fuel filters and go from there. If you want to have this checked, a technician from YourMechanic can come to your car's location to diagnose the stalling issue.
