HI,

Sounds serious. If the truck is still running right the PCM may be going out. Start buy spending $30 dollars on a speed sencor attached to the top of the differential that should remove the OD flashing light and the ABS Light also fix the speedo not sure about the service engine soon light that could be many other problems..Your Vehicle velocity sensor has gone bad or the wire harness has gone bad. Check the wire harness first and if that is good, then replace the sensor. You can find the sensor on the transmission out put shaft on the drivers side

Thanks for contacting Fixya.

The same thing happened to my 94 volvo 960 the engine belt was having the same problem, i changed it the belt, it was fine for a few miles after that it just died, does not fire, not sure if it is getting fuel, but the mechanic says the timing belt went off. you may have to check the crank sensor on yours.

yes brakes need to bleed again starting with the caliper farthest from master cylinder abs pump is fine

Get the following checked even though i have strong feel that it is the fuel pump.
Check the coolent level / waterpump / thermostatic. If all is fine replace the fuel pump.

Let me know if you need further assistance

Thanks

1)make sure you are not driving w/brights on.2)check to see if your hazzard lights are functioning.3)look in your opers manual then call dealer who will tell you for sure.

Did you have the head machined/shaved before you replaced the head gasket with a new one? If not--do over---machine head---replace gasket.

BUT, before you even bother, have you considered the fact that the BLOCK may be cracked? You can check this by looking at each spark (plug for combustion residue of coolant or oil) of each cylinder separately.

Check your ignition/fuel pump relay---it's with all the other relays in a dash tray---it's ORANGE---check it for dead-short.

look at the buckle and see if there are two wires going into it. if there is cut those and wire them together. or you can try and follow those wires back until you hit a fuze or something. alot of times though that fuse is shared with something else silly like a dome light or radio though

The original response is correct about acquiring the code from the dealer. However, if you just purchased the car, check inside the glove box/manual as it may be located there. Also, you may want to try pulling the radio out of the dash. I have found them written on the radio as well. Defeats the purpose, but some people do it anyway.

I have that same problem,did not play with just order this bypass plate,from IPD no more problems

Sometimes the fuse looks good,but replace it anyway,that sensor in under your dash,its red and round.

The speed sensor should be in the rear differential. It should have a two wire connector going into a sensor on the back of the case cover. The wire is known to break from time to time right at the connector. Sometimes the wire breaks inside the insulation. Gently tug on the wire it it's broken inside it will completely break when you tug on it.

If the wire isn't broken use an ohm meter hooked up across the two sensor connectors. While watching the meter (with the car in neutral with the rear tires off the ground and the front wheels chalked in place. Also make sure the car is supported on jack stands) turn the drive shaft, if the sensor is working the ohm meter will start to fluctuate. If there is no reading the sensor is bad. This is not common, but it happens.

If the reading is normal and the wire is not broken the you will have to check it at the instrument cluster, but I don't know what wires to check at the cluster, you will need to get a shop manual or wiring diagram.

If I remember right that cluster has a "U" shaped pins in the connector that attach to the wiring plate. Use a pair of pliers and close the "U" shape down a little. They are known to expand over time and cause a loss of contact.

I hope this helps

I'm pretty sure that you can call any Volvo dealer and get the code...talk to the service manager.

You can pay for codes online but there is no real need to.

Is the problem a burnt bulb or broken headlight? The bulbs come out from under the hood...there is a black serrated knob to losen and pull out...the bulb should be resting within the piece.

Don't touch the bulb with your fingers....only the perimeter. Bulbs can be regular or special high intensity ones...at any parts store. Easy to do.

Best bet is to talk with the local Volvo service manager..or a skilled mechanic. Normally, I don't think any real service is needed,unless there is a problem. Changing oil every 3K is good..not racing the car (turbo) just as you start up or shut it down is helpful too.

The mount on the rain gutters...Thule, Yakima, etc. Get locking feet...worth the extra money.

I think you can also get some for hanging off the tailgate...check with the companies online or in a local dealer.

hello
fault IAC valve

Is this a question or a statement? It's common for the water pump, radiator or heater valve to leak. Whee is it coming from?

replace fuel pump

humming noise?? a fan belt or something associated with it
