Volvo 240 4 cyl ignition Distributor control unit - For the "white cap" distributor cars, - Chrysler Ignition.  These units are quite rare, as they only came on SOME US model 1981 1982 & 1983 Volvo 240 models with K-Jetronic fuel injection.  These units are a frequent source of issues for these cars causing a no start condition.  My friend Irv from the recyclers yards still runs one of these cars on a regular basis!  he loves it.  In addition to these control modules failing, occasionally the wiring running to them gets corroded, check your connections first.  This unit is now quite rare!

So anyway, this should be a good used unit - and I will give a 30 day warranty on this unit!  I have just this one!  Rare unit from a 30 year old car.
