I have 340 1.4 CVT volvo from 87 or 86, ive checked everything and there is no spark at all. I bought new coil and capacitor, still no effect, there is earth and +12V on white plug (the renix thing), engine speed sensor is working (around 200ohms). Is it the renix control unit broken? I checked and it shows 1500ohms not 0 as you said (where the coil is plugged, 2 bolts).
Its number is 406031-02 S 100750 416 A, i cannot buy this anywhere on earth eh :/
Any advice?
