I have a 98 GT with 55,000 miles and have had problems starting the car since I bought it last sumemr. Sometimes it takes 3-4 seconds for the car to actually start up. I did a full tune up and changed the fuel filter. It basically coughs and hesitates, BUT ALWAYS STARTS. Somtimes it starts right away (when it is warm) and sometimes it takes a good 4 seconds to finally start up. A couple of mechanics tested the pressure and said I need a new fuel pump since it was not holding pressure, but being a California emmissions pump, its gonna cost about $400 w/ installation for the stock pump. I dont know if I am losing any power because of this and dont know whether it is a smart idea to change the pump or if I would be able to keep going with just the inconvenience of the stuttering before the car starts. What do you guys think? Any experiences or opinions? Thanks for the help.
