help ... no spark
Good day everyone... I'm at a loss... I am in the process of prparing a 1987 944 for track purpose only.. just before taking the car apart in the fall.. I stripped all the wiring that was not necessary...and mad sure it runs... Now, after the rebuild, I get no spark... I have replaced both flywheel sensors and the gap is good, I have followed all the testing procedures from the Porsche repair manual...eerythings checks up good... I have battery voltage on both side of the coil, but never a trigger to the distributor.... any thoughts ??

I have a nasty oil leak.. I think from one of the balance shaft seals, but could care less. I can fix that in no time at all. I am going out to pull the covers when it cools down to see what's up.
Many thanks to Andy for letting me use his DME and KLR. At the same time I also bypassed the alarm with pins 1 and 4. I will swap in my DME later and see what happens.
Tip for the future (and I will post this soon, and thank you Bader$), 87 and earlier cars, for the alarm bypass, it is 1 and 4 only. Later cars, jump 7 and 8.
Thanks again to everyone on the list, you are a major reason this baby is here.

86-88 Cars
The Control box is above the DME in the passenger compartment. It is a 3"x5"x2" black box with blue lettering, and has 2 connectors. One connector has 2 wires and is the output of the control brain. The other is an 8 pin connector for the various inputs. To disable, unplug both connectors and with a jumper wire, jump pin 1 (green) to pin 4 (red/black). The early cars do not have a fuse or relay to bypass the alarm control.
89 and later cars
There are 3 components to the alarm. The control box, a fuse in the main panel, and also a relay in G18. Assuming the fuse and relay are fine, remove the connectors as stated above. (control box also above the DME) Jump pins 7 and 8. If it still won't start, try jumping 4 and 6 as well.
Since I do not have a later car, I do not have the wire colors, but other posts have said this procedure works just fine.
Happy disarming!
