Ok all you 240sx pros in the forum. I just got through rebuilding my KA24de. It was all cool and everything, but when everything was all back together and I tried to start it, it was turning but it wasn't actually starting...(a nightmare come true) so far i have replaced the fuel pump, distributor, Fuel pressure regulator (FPR), and managed the ECU. still the same thing is happening. OMG someone please help...so frusturating!
