Hi there, i'm new to this but here's my problem, my 2002 V70 fwd non-turbo stalls out while driving or idleing at any rpm, it just feels like the power was shut off, i'll pull over and wait about five minutes then it restarts and drives fine till it stalls again. I have had the ETM replaced and software update plus a new fuel pump with new relay and fuel filter, this was done at the dealer and the problem went away for about 6 months, its back but this time with a message E.Power Distribution Module failure, I did research and a helpful service advisor said that this module distributes electrical power to various modules and when it overheats/fails it will cut power to other modules and stops communication therefore random stalling, now the reason it resets is because you recycle the ignition key. So i'm close to solving this problem but need help since the volvo parts dept can't find a electrical power distribution module in there parts list but the message is right on the dash fault message board, has anyone seen this before? I know its complicated but since its on the message board that means the ECU picked it up and its a matter of finding the part and its location in the car to fix this problem for good. Love the car and want to keep it if I can solve this mystery. I appreciate any imput. Thanks

 

I ran into this before. Let me look in my notebook at work as to how I fixed it. I will post back later.

 

Thanks guys. I will eagerly wait for your imput lifesgoodhere.

 

Finally got it fixed, had to take it to the dealer after the local guy was at his wit's end, they hooked it up to there portable computor and test drove untill it stalled, ended up being a module overheating therefore was not communicating with the main computor properly and telling the car to shut off, they replaced the module and reprogramed the system again and its works perfect now and hasn't stalled since, now im back to loving my volvo and will keep it for many more years. I hope this helps someone out.

 

I never found my notebook sorry for not getting back. Glad you got the issure resolved,

 

Which module did you end up replacing? The E-Power Module? I'm having the same problem with my 2001 V70 right now and they're telling my that I need to spend $700 to replace the Fuel Pump.

 

For the love wagons, please tell me somebody solved this problem. I’m dealing with the exact same problem. 2002 Volvo v70 non turbo

 

I just sent a PM to Bob333 but he solved his problem 7 years ago.
There is a module externally mounted on or near the gas tank which controls the fuel pump. This is the only item I can think of.
Come 2006 and 2007 Volvo relocated them into the spare tire well.
If you get a car from that era I suggest gluing the feet down with silicone rubber as they leave the module just swinging about.

There may be a diaphragm style pressure regulator at the end of the fuel rail. These can fail and they aren't too expensive.

 

Thank you for the info. I will investigate tomorrow. A little back story, I was experiencing that exact problems As listed before by Bob. I had a check engine come on before the symptoms started. The codes were for a oxygen sensor bank 1 sensor 1 and thermostat control sensor. Admittedly I postponed fixing my car because I was broke at the time then it started going all goose whacky. I then replaced the thermostat sensor. Car behaved correctly for 2 weeks of daily driving then the symptoms return. Replace the O2 sensor no symptoms for 11 days. Cleaned throttle no symtpms for 4 days. Still no check engine light either. I keep driving it hoping it will come in. I’m at a total loss

 

Just for accuracy: The sensor you replaced was the coolant temperature sensor (in the thermostat housing), yes?

Since you're in Seattle you might want to contact the people at IPD just south of you in Oregon.

Since a module may be involved it may be easily read specifically by a VIDA which they have. Since your car drives I suggest you take a chance and ask 'em for a reading

There may be local mechanics by you with one as well.
