Picoto Posted October 15, 2020 Share Posted October 15, 2020 Hi guys having some issues with my supra. It is a NA-T running gs300 coils and 7m gte cam position sensor. Sounds like timing wrong but it has been checked not just by me but a few people. Also we have replaced sensors cps. Car is running a gte ecu with a emu det3 piggy back. I know piggy back is not great but it been runining for over two years and now just won’t start. https://www.facebook.com/1058108026/videos/10222338634468897/ Quote Link to comment Share on other sites More sharing options...
rider Posted October 15, 2020 Share Posted October 15, 2020 If timing is good and it won't start then it has to to be fuel or spark. I'd start with the fuel pump, then look at the fuel pump, check the fuel pump again and go onto the ignition side from there. Quote Link to comment Share on other sites More sharing options...
Style Posted October 16, 2020 Share Posted October 16, 2020 Yeah as Rider has said, start with fuel as it's easier to check than spark with the NA's intake running over the top of the head. If fuel looks to be fine, pull a plug and see if it's getting spark Quote Link to comment Share on other sites More sharing options...
