I am getting ready to sell my 98 Cav 2.2l and it has developed an odd stalling problem, when it sits for more than a day the first time you start it up it will stall within 20 seconds or so and then restart fine like nothing happened and not do it again until it sits for more than a day again. When I drive it everyday it does not happen. I am thinking fuel pump is going bad and bleeds down when it sits without running too long?? I hate to blow the $$$ on a pump as it appears to only come as an assembly and it costs around $275 locally and that will make me pretty much in the car for what I am selling it for plus my time doing it. Anyone else have this issue??
