sounds like you got a whole lot of problems. For one if the water pump leaks you need to do the timing belt pulleys and tensiors as well as the hardware. For the fuel pump i would try and correct the leak first. If you pay more then 800$ (Canadian) to have this first job done you are over paying. For most brake faults the rear tail lights tend to get a short. Try removing the tail light panels and clean the contacts. do the same for the license plate lights. you have a 50/50 chance at clearing the fault this way. The fuel pump may not be working if the car is reading enough coolant for regular operating amount
