my 2003 sunfire keeps blowing the 15amp injector fuse when i try to start it. I had it serviced and no problems wher detected. After service it ran ok for about a week then blew the fuse again, and now it blows each time I try to start it.

It sounds like you have a ground either in the wiring or in the injectors may be grounding. For a fuse to blow indicates a ground, it is protecting the wiring from a meltdown.
