'99 S70 AWD about 130K - have had a couple of weeks - hand-me-down (Thanks Mom!) I've noticed the idle was a little low a couple of times on start up. The problem has been that after driving the car, I've shut it off for a few minutes to run an errand and then tried to start it and it's either not turned over or it has caught and then sputtered out. I typically waited a few minutes and then started the car and drove on my way. This happened 5 times over 2 and a half weeks. This morning, she never started back up. My old 850 Turbo had a similar issue that eventually led to fuel pump replacement after changing the fuel pump relay. Am I on the right track? or should I also be concerned with the Electronic Throttle Module and /or the Mass Airflow Sensor, Idle Control valve? Thanks.

 

If the car is not turning over it may be a bad battery???

 

The engine is trying to turn over but it seems like it is not getting fuel. I'm going to swap out the fuel pump relay from an 850 I have and if that doesn't work, I'll replace the fuel pump. Does that sound like a reasonable progression?

Thanks
