Intermittent signal to ignition coil Spider

[Paul Kessels <paul.kessels@domain.elided>]

Hi there,

As described in previous postings i have some problems with starting my '86
Spider Bosch FI. I figured out that the reason of the nonstart is that the
ignition coil does not receive the correct signal. I have current on the
plus side but every now and than the ECU does not give the intermittent
signal ( - side) to the coil. One's the engine fires up there is no problem.


I checked all sensors. They measure oke. Does anybody know which device
determines whether or not the ECU sends  the intermittent signal to the
ignition coil?


Regards,


Paul
