Folks:

Here is the Reader' Digest Version of my problem. My wife's 99 S70 base was struck head on a couple of months ago. After getting it back from the body shop, the brakes were a little weak. After bleeding them out all seemed well, except for an occasional drastic drop in RPMs when braking hard - I looked for vacuum leaks and could find none - although I don't have access to a smoke machine to really look things over. This was manageable until a few weeks ago when there arose a hard start/no start problem - the car would turn over fine, start then immediately die. This would happen intermittently - no "rhyme or reason" that I could tell. I replaced the fuel filter just to see if it made a difference and the problem disappeared for about a week. Now, about every third or fourth time we go to start the car this happens. I figure it is either fuel or spark, but I would think that either would be consistent. The thing is, once it starts it will be fine until the car is parked overnight. There are no codes stored and the check engine light is not on.

Could the accident caused an issue with the fuel pickup or something to that effect? Besides fuel pressure, whac should I check?

My wife said that on occasion she could "turn the ignition switch back a little" and get the car to start, although I have not had that success. Could the electrical part of the switch be at fault here?

I don't have access to a repair manual - so when I go to check fuel pressure, what readings should I look for?
