Maybe another candidate for the Bosch relay mod.
The nuteral switch thing only works when it is the problem.
Both my SVX's developed the same erratic starting problem and after month of testing and frustration, the bosch relay changed my life! Thousands of starts later and everyone has been a faster start that it ever started before the Bosch relay!
Best to test it but that has to be done while it is failing to start.
Do your radiator fans come on when it fails to start?
This would be totally unrelated to the temperature of the coolant?
Hope it gets worked out soon!
