if the fuel pressure is reading zero then your pump is either to weak to get the fuel to the engine or you have some trash in your fuel filter . should be around 30 psi if i remember correct. . change fuel filter first and then check your pressure again before replacing fuel pump. im taking it that this car has injectors could be those as well. harbour freight has a fuel pump /injector pressure kit tester if you need one around 10.00 got one not to long ago .
