98 volvo s70 stalling out, then finally after a day wouldnt start

My 98 volvo s70 glt was stalling out for like a day or two then the last time it stalled out and would start again. we had in the past taken it to auto zone for a check engine light and it had something to do with the air pump. would this have anything to do with it?

    the air pump pumps fresh air into the exhaust to help it burn the old gasoline fumes up in the cats...no it wont make it stall. try to shoot a little gas or starting fluid into the air cleaner and see if it will start up if so its a fuel problem if not you have other problems thanks Jerry holler if you need more.

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.

The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.

98 Volvo V70 GLT - Oil Pump or Valve Job?


Most common cause of ticking in these is the oil pick-up seals. Remove the pan and replace the oil pick-up tube seal, the two seals for the tube in the pan and the 2 O-rings on the right side of the pan. And dont use silicone to seal the pan back up, because it WILL leak, I highly recommend the Volvo sealant
