20 Most Recent 2007 Volvo S40 2.4i Sedan Questions & Answers

my volvo car dose want to start when i want to switch on the say( ANTI-SKID TEMPORARILY OFF) and all light right hand said coming red and left hand said coming yello.

Is there actually fuel in fuel lines?

Take it to a good Transmission shop, sorry but it won't be cheap.

I had a similar problem with my 1999 S80. Give this a try. You don't need any mechanical experience. At no point will you come into contact with any gasoline. This is a five minute fix if it's what I think it is.
Background: when you gas up your car, it goes down a tube to the gas tank. There is a vent on that tube to let off gas fume pressure that can build up in the tank. If the vent gets clogged pressure builds up in the tank. Modern gas pumps shut off when that pressure comes back up the tube from the tank. I think if you clean out the vent with a Q-tip you'll solve your problem. At least, it worked for me.

1. Get a flashlight and some Q-tips (I suppose anything long and pokey will do).
   
   
2. Go to where you put the gas in (you don't need to open to door or take the gas cap off).
   
   
3. Crawl under the car behind the tire and look up with the flashlight to about where you'd put the gas in. You should see something like the picture below (taken from my 1999 S80). Note that at the end of the red arrow, you can look up inside the tube a bit? When I was having this problem I could only see what looked like white cotton inside the tube. It turns out it was an old spider's nest. The spider was long dead from the gas fumes, but his nest made it impossible for me to fill up my car!
   
   
4. 
   (fig. 1 - a vent for the tube that leads to your gas tank)
   
   
5. Place a Q-tip in the hole indicated by the red arrow. Swirl it around a bit. You shouldn't have to jam it or be very forceful. The Q-tip should remove any blockage.
   
   I suppose it's possible that when you open the blockage some gas fumes will vent out, so don't be smoking while you do this :) Now that I've said this, to be super-duper safe why not do this outside away from any chance of open flame.
   
   
6. Go gas up your tank and see if it works. It did for me.
   
   

Good luck!

look for a loose or broken vacuum hose connection , pcv valve fault

I had the same issue, reason Of the vacuum pump to work continuously is either a leak in the vacuum pipes btween the pump and master cylinder or "which was my case", the vacuum switch or sensor between the master cylinder and vacuum pipe is not functioning properly. Replaced and everything works fine.

Your ignition needs replaced. They weren't the best on Volvos; especially if there is a lot of weight on your keychain.

Yes you have a bad headlight socket gound.

A good way to check for ground continuity is to use a multimeter. If the socket has two wires , one will be positive + 12 volts DC or so. The other wire and connector in the socket will be the ground. Put the multimeter on DC volts, 20 volt range, and place the probes into the socket. If you know which socket wire is positive, place the positive(red) probe in that socket connector, and the black probe into the other connector, which is the ground. When you turn the headlights on, you should get a 12 Volt reading, more or less on the meter. If the meter shows a negative sign or the needle deflects to the left on an analog meter, reverse the probes in the socket. If there is no voltage reading, giggle the wires in the socket to see if the problem is in the socket. Also, keep the positive probe in the socket and make good contact with the black probe on a part of the car body. If the meter shows 12 volts then it shows that the socket is getting current (Voltage), so you know the positive wire is good. You can also check for continuity of the ground wire. Turn off the headlights. Put the meter on the continuity setting. On this setting, when you touch the two probes together you will here a buzzing sound. Place one probe in the ground connector of the socket, and make contact with the other probe on a good ground on the vehicle. It doesn't matter which probe is connected to ground. I there is a good ground, the meter will buzz. If it does not buzz, there is a bad ground betwwen the socket and the vehcile ground.

alternator belt braking would not stall the engine but your dash would of lit up like a christmas tree. you will need to have the engine on an obd reader to see what the problem is. did the belt snap or was it stripped ? alternator over load would cut the engine out check the fuse in the engine fuse box there is 2, 80 amp fuse in there check these are fine.

I am thinking faulty injectors and/or excessive fuel pressure in the fuel manifold . Run fault codes again ensuring that the cables used and the procedure to connect is adhered to as there will be a fault code recorded but not being read
