When car stays overnight and engine is cold, it starts with no problems and runs great. There is no starting problems even when engine at normal working temperature; however, if I park for a couple of hours after regular driving meaning that engine cooled down a bit, it won’t start. There is no even one fire when cranking. It will start again the next morning without any problems.

First time it happened when I took 500 miles trip with my wife and on the way back we stopped for a couple of hours for a dinner. It wouldn’t start. On the second attempt I pushed gas peddle a little and it started. Then we drove 150 miles without any problems. Everything was great again for about a week until I needed to start it after I parked it for about 3 hours. It wouldn’t start, but I knew what to do - pushed gas peddle a bit and it started. Last night it wouldn’t start again after parking for 2-3 hours, but pushing gas peddle didn’t help either. I left the car on the parking lot over night, and it started this morning and ran great without any problems. Now the car is at home and I am planning to find the problem.

I suspect there is a problem with fuel supply to injectors. I searched this forum and it appears that I should look for fuel pump, fuel pressure regulator, fuel pump relay, or Mass Air Flow sensor. I think that problem is with MAF sensor. It resolved similar problem for someone on this forum, but his one was 98 S70 which makes me think that it may not resolve my problem. My car is in great condition with 125k miles which is not much for this year and I love this car. Any ideas or suggestions would be greatly appreciated.
