dangerous brain Posted October 24, 2010 Share Posted October 24, 2010 Funny I had this same issue with a HKS fcon unit. An old unit. To complicate it further if I changed my ignitor unit it would then run. Very bizarre. I also had a toad alarm system. Maybe a weak ignition unit.

pauld36 Posted October 28, 2010 Author Share Posted October 28, 2010 THE ANSWER COURTESY OF RYAN G MY NEW GOD,it was the crank sensor,now the explanation. supras have 2x cam sensor and if one breaks the standard ecu will switch to the other sensor,however the hks f con wont switch thus not work,cannot thank ryan enough ta mate Link to comment Share on other sites More sharing options...

Chris Wilson Posted October 28, 2010 Share Posted October 28, 2010 I think the original poster meant it was one of the CAM sensors which failed, not the crank sensor. If the CRANK sensor failed neither ecu would run it. The reason for two cam sensors is to promote an engine start within minimal crank rotation for stringent cold start emissions reasons, or so I was told Link to comment Share on other sites More sharing options...

Chris Wilson Posted October 28, 2010 Share Posted October 28, 2010 If it's pretty much totally stock, probably, but it will show a fault code if that's the case. Link to comment Share on other sites More sharing options...
Lurch Posted October 29, 2010 Share Posted October 29, 2010 Oh right, No faults lights on the dash, so maybe just a slow starter. Has done 200000km Link to comment Share on other sites More sharing options...
