2001 V70XC just dies or does not start randonly. After leaving sitting for an hour it always restarts. There is no indication it is going to do this, just driving along, lose all power and glide to the side of the road. It has the latest volvo update for this vehicle as there was an issue about this. It is like the immobilizer has gone off, i can turn it over well, just not one bit of fire. I have never been able to check if there is a spark or not as it always (4 times in 2 months) happens away from home and my tools. I have heard that there is supposed to be a signal on the panel that says immobilizer activated, but mine does not show this. Anybody have this issue or have any ideas. There is no codes, the dealer does not know, I have changed the fuel filter thinking perhaps it was partially plugged, no use.
ps. hope no one minds, I will cross post in the XC70 forum, as whenever i buy a part and say V70 XC , they always feel they are correcting me by saying "Ohhh, an XC70", I guess as it is the "cross over"year?
Thanks!

 

I have not hard of the V70's having issues with that but the battery would be one thing to check, fuel pressure would be another (when it's not starting). Older Volvo's have issues with fuel pump relays going out and not tossing a code.

 

If i ever have it at home when it fails i will try and think of a way to test and see if the fuel pump relay is working. I tried to see if i could hear the fuel pump kick on when i turned on the ignition without starting, (when working fine), but could never hear it.
