theres not much to wire, best thing is to worry about the proper part then go from there.

Does the car throw a check engine code? If so, what is that code?

This could also possibly be the ignition. My V70 had a bit of trouble on a couple of cold mornings. I replaced the ignition switch (located in the steering column on the opposite side of the key hole).

Also check the fuel pressure and fuel filter. Could be a pump and filter problem. Fuel condenses at lower temperatures and if the pump is having issue pushing the thicker fuel through the filter, take a look at that to be an issue.

Lastly, check the throttle and the fuel injectors. Run fuel system and injector cleaner like HEAT through the fuel tank to see if it helps.

-I never work on Volvo. But most car the fuel pressure regulator
is locate and connect to the fuel rail that connect to the injectors.
-It's on top of the engine.

sounds like a coil issue

yes under the bonet dhould be near the battery in a plastic box

did you check your fuel injectors? they could be dirty or clogged

If the fuel pump is new, then the problem may not be the pump. It could be the Airflow sensor, get an OBD(on board diagnostcs) check and if its the Mass Air Flow Sensor (MAF) it will read so or other electronic sensors and control. These are usually not repairable, you have to buy a new one.

THE S-70 IS LIKE THE 850 MODEL IT SOUNDS LIKE A FUEL PROBLEM AND FUEL FILTHER AND ALSO CHECK THE PSI OUT OF THE FUEL PUMP
