Volvo C70 Problem


You will have to provide more information, what year / engine size / fuel type (I assume petrol as you're stating there are spark plugs). Also what was done when the engine was rebuilt, and why didn't the garage that did it check the engine was running before handing back to you?

If you did the work, please list what works were done and what was replaced.

If it is a modern Volvo you may find that, as with many modern cars, sensors that are replaced need to be linked with the ECU before use. If they are not then their input is ignored by the ecu.

Does an exact fit used ECU need to be reprogrammed on my 1998 s70 volvo


You can try a Hard Reboot, remove the battery cables from the battery, wait 20 minutes then make contact with the + an - cables together for at least 10 seconds. Normally you would want to run a diagnostic on the new computer if it cam out of another car just to erase the codes from the other car.

Where is the ecu located? 2000 Volvo S40


An engine control unit (ECU), also known as power-train control module (PCM), or engine control module (ECM) is a type of electronic control unit that determines the amount of fuel, ignition timing and other parameters an internal combustion engine needs to keep running. It does this by reading values from multidimensional performance maps (so called LUTs), using input values (e.g. engine speed) calculated from signals coming from sensor devices monitoring the engine.

ECGU? where on the engine is it?


You mean ECU, Electronic Control Unit, the computer brain of your car. You can get it analysed (and replaced) at your Volvo dealer.

The ECU itself is not likely to be the cause itself, it's probably something else causing the ECU to stop working, like bad wiring, a failing sensor, a broken part, etc. Hopefully the ECU just shut your car down to prevent any (more) damage caused by something else. As stated the dealer can diagnose and hopefully fix this.

How to change bulb in headligth of volvo v70


For the RH headlight, First remove the top cover of the ECU module just behind the headlight. Then remove the middle section leaving the ECU in place. Both parts are just clipped in so should come out fairly easily. You will then be able to get access the the headlight bulb, release the spring clip at the top (using a mirror helps) and the bulb should come out.
For the LH side remove the air filter housing.
