The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

It could be the filter. Has the fuel been changed after storage? I would also thing the Carburetor or the fuel injectors might need to be cleaned.

Hi!
I'm presuming the B23 engine? Have you checked fuel pressure valve located on the inlet manifold, are your plugs getting soaked in fuel?
If not try looking at the Fuel relay in the block situated behind the ash tray below the Radio.
It might be easier for you to access this by taking out the coin tray, flip the cover plate off the cigar lighter it will reveal 2 screws, take that out and the tray then you'll see a whole lot more relays.
There are different types/colours I'm guessing your could be Blue but there are white ones too.Try Jiggling them carefully then crank the engine if it runs but poorly replace.
You must replace with correct one even if it is Blue some have Copper Lugs others steel and they are different.
Good Luck!

It's in the console under the coin holder, in front of the gear shifter. You have to remove the coin holder and you will see it.
