My 2003 volvo s40 won't start but turns over. What could be the problem. I know I needed a thermostat but the engine is not over heating. I changed the fuel pump fuse.

SOURCE: 2001 Volvo s40/ takes 5-10 seconds to start.

fuel filter is at right side of gas tank undernieth car
by pumping the gas all you are doing is opening the throttle plates alowing some air.its not uncomin for injection cars with higher mileage to need alittle more air for start up.
check ECT sensor.
clean throttle plates
is check engine light on?

SOURCE: want to replace signal fuse in volvo s40

i have a 98 s40. The fuses can be found internal (under the dashboard near the bonnethandle). Inside it you can find the fuse clamp and extra fuses. These can also be used for the external fusebox under the bonnet.
I have found the fuse that might be broken, but i can't replace it because it has some extra casing. It's for internal lights and the alarm.

Where is the fuse located for the 12 volt accessory plug in the front passenger compartment?

SOURCE: How do you reset the check engine light on a volvo

The Check Engine light has nothing to do with changing the oil. The light is on because there is a problem with the emissions system. Even if you reset the light it will just come back on unless the problem causing it to come on is repaired. You will need to have the ECU scanned with an OBD2 scan tool. That tool will retrieve the code that has been set by the ECU. The code will tell you what part is being effected, but not necessarily what part or parts are defective. To determine that takes training, experience, and diagnostic skills. I suggest you seek professional help. If the engine is running fine there is no hurry but if it is not running as it should, then do not put this off.
