Re: HELP: ****sche 944 no spark

The ignition coil works by rapid collapse of the voltage in the
primary coil.  If the primary and secondary show propter resistance
then the coil is probably OK.  The sensors can only be tested with an
oscilloscope.  They may have slipped in position.  You need to check
this.  Go to http://www.clarks-garage.com
for more specific data.
Have two 944's and have been through this drill  a few times.  If you
have an older model that has been stored outside your problem is
probably a bad connection on the blade connectors on the relay
panel.   Try wiggling the wire mass when starting to see if it fires.
