My car had been running fine until a couple of days ago after a big rain storm. Now it has trouble cranking and shakes and backfires. It happened once before but only briefly just after a quick rain shower. Its been awhile since it rained but it still is doing it. I will get it moving but if I stop at a light it cuts off and wont crank back up unless it sits for awhile.

ALL THE B230F ENGINES OR 240/740/940, IF YOU ARE HAVING AN ABNORMAL DRIVING CONDITION, START WITH REPLACING THE FUEL PUMP RELAY AND SUPPRESSION RELAY. THEN RE-EVALUATE WITH WHAT THE CAR DOES.
