Fuel pump issues
The fuel pump in a car is responsible for delivering fuel from the tank to the engine. Fuel pump issues in the 1986 Oldsmobile Cutlass Calais can manifest in several ways, and there are a few troubleshooting steps and potential solutions to consider.
One common issue is the fuel pump turning on, but no gas is coming out of the line at the carburetor when cranked. This could be due to clogged fuel lines or a faulty fuel pump. Before replacing the fuel pump, it is recommended to try a few other solutions first.
Firstly, check if there is fuel in the injector body. Disconnecting the fuel lines at the injector housing will help determine if fuel is reaching the injectors. If there is no fuel present, it could be an issue with the fuel pump or a clog in the fuel lines.
If there is fuel in the injector body, but the car still won't start, it could be due to crossed wires. In this case, you would need to find a wiring diagram and uncross the wires to resolve the issue.
If the above solutions don't work, it is likely that the fuel pump or fuel filter needs to be replaced. It is recommended to replace the fuel filter first, as a clogged fuel filter can restrict fuel flow and cause the fuel pump to work harder than usual. If replacing the fuel filter doesn't solve the issue, then dropping the tank, cleaning it, and installing a new fuel pump may be necessary.
It is important to note that fuel pump issues can be complex, and in some cases, it may be advisable to consult a professional technician to diagnose and resolve the problem.
