Hi there all - I've got a 1991 Hatchback that really deserves to come back to life, but I cannot figure out how to get spark...

I've replaced the Cap & Rotor - and the coil... I have power to the black & yellow wire and power to the white/blue wire, but no spark.

I found a grey box, with a 16 pin conector with a white & blue wire amongst many others tucked up underneath the passenger dash, and my assumption was that it may be a defunct car alarm - inside the box, the circuit board is labelled "STANLEY S-386IF" and on the outside, it only has "MF06" The harness that goes to this box, joins in right where the ECU wiring meets the firewall, and it looks stock, so I didn't pull it apart to look at it yet. I did remove the odd gray box and it's sitting here next to my computer.

Afterwards I did remove a Solenoid from the main fuse box under the drivers dash, but no luck.

Can aybody point me in any of the right directions ? Any help would be great, as the haynes manual I have doesn't even have the proper schematic for a 91...

Thanks,
Ken
