Hey Guys....long time no talk. Can anyone tell me where to locate the Fuel Roll over switch on a 95 850 Turbo Wagon.....I think it might be getter corroded and stopping me from starting once in a while....mostly when its hot, hot , hot out....and its like that this week.

What is a fuel roll over switch? That's a new one to me.

 

Are you talking about the fuel pump relay?

 

its suppose to be a switch that has contacts inside so if the car rolls over, it cuts the power to the pump for safety reasons.

 

I just went thru my book and cannot find any on this car. Maybe the Mech was wrong and this car does not have one....lol

 

pretty sure it doesn't. sounds like the fuel pump relay to me.

 

I think I had a faulty relay and the pump went at the same time. I replaced the pump and it did the same symptom that night. I then changed the relay 2 days ago and it has not done it since. I was just following up on a suggestion from a Mech on any other possible things it could be. Lets hope this does it, its aggravating at times. Thanks for the help guys.

 

I haven't looked for a roll over switch but I haven't come across one in the wiring diagram either. I don't these have one. Being Volvo you'd think they would have been the first ??

 

Yeah, your issue sounds like a relay issue.

Glad you got it fixed!
