Volvo Ignition Coil Module Bracket Assembly 1367438  Up for sale is a good working Volvo 4 cylinder ignition amplifier. This will work with all Regina 940 / 740 models. These generally last around 150,000 before a failure, but when it does fail it will prevent the car from starting. If you have no spark this is often times your problem. This is the device that "hears" the hall sensor in the distributor, fires the spark plugs and tells the ECU, "we are good to go, turn on the fuel pump and start working!" Generally if there is a problem with the ignition system on older volvos it's either this unit or the wiring to the hall or crank sensor that goes bad. These are fairly easy to replace, and they are over $287 from volvo for an OEM Siemens Unit
