One problem related to fuel pump has been reported for the 1999 Mazda Miata. The most recently reported issues are listed below.
The fuel pump on my 1999 Mazda Miata stopped working. I changed the fuel pump and saw that the fuel pump connecting plug was a hot connection. This bad connection, which is inside the fuel tank, was the cause of the fuel pump not working. The fuel pump is good the plug-in connection is bad with signs of the connection heating up. I can send pictures if needed. This bad plug-in connection could cause the fuel tank to explode. I have the bad fuel pump/tank level assembly which all installs inside the fuel tank.
