My 93 rx7 13b starts at only at cold start but then dies like at 2 min jus sitting there and while its running theres a lot of smoke coming out the exhaust. Its a single turbo conversion with both 750cc primary and secondary injectors running on a 255 fuel pump. The previous owner had an Apexi Power FC and a Hks EVC-S boost controller but removed it from the car. And now im using my brothers Power Fc but I have no boost controller connected yet but the valve is still there but starts only at cold srarts and when i decide to turn it on again it wont start at all. What could be the issue with this? Does it need a proper computer tuning?
