Engine Performance problem
1987 Volvo 740 4 cyl Two Wheel Drive Automatic 214699 miles
I have a 1987 Volvo 740 turbo. The car wont start at all, it just cranks. Now sometimes it will start and ill drive it, but when I go into the store or when I fill up gas, it won't start. I would wait couple of minutes then it will start again. But recently now it won't start up on my drive way. Now I checked for spark and its good. So I checked my fuel pump, I can hear the outside pump buzzing but not the one inside the tank, so I replaced it and the car started to work again but after driving it and then letting it sit for an hour the car won't start again, just keeps cranking, I checked the fuel pumps again and both are making the buzzing sound, so I checked spark again and I still have spark because I sprayed some of the starting fluid and it fires up for a couple seconds. So now I don't know what to do. I'm completely baffled.
