Doesn't do it after short trips. Once it sits for an hour or so it will start again. By the time we can get it hooked up there are no problems. We replaced the fuel relays thinking it was a fuel pump problem and we have seen the posts regarding PCV and IAC, but mechanic says they check out OK. Saw one post saying the coil pack may be going out. Haven't replaced the fuel pump. Any ideas before I start changing things that aren't the problem?
