My 99 GT has gave me problems a couple times this week not wanting to start. It will start, and sputter a couple times and then die. After switching the key on and off, sometimes a dozen times, it will start and run fine...................I kept checking the fuel pressure today by turning the key on, then I would relieve the pressure and check again later. A couple times I was getting 10 psi. A couple times it read 30 psi, and after that I was getting 40 psi everytime. So I am thinking my pump maybe on its way out, but Id like to hear some input from others who know more than I before I spend $200.00 on a pump............Thanks
