99 se 3.0 - Last week end made a quick run to china-mart and got in to leave and no start, good cranking - popped hood checked things out, made sure everything was tight, after about 15 min. of just sitting deciding my next move I tried it one more time and she fired but ran sluggish for a few minutes and fine driving for 3 days, same senario as last week different actors this time it happened with wife and a few bags of groceries, calls me at work car wont start (she cranks it down to nothing) got a buddy and some cables got there and she fired up and drove perfect for 2 days, yesterday same thing stalled out at target parking lot so went and picked her up went back put about 5 hours later and fired up drove home and I tagged her out. I didn't really hear the whinning of the pump when turning key the key at first but after awhile sitting when I turned the key I could hear it engage, I know there is a whole shopping list of what the problem could be, relay, pressure reg. on and on. Any one else been there done that? Thanks in advance.
