I have a seasoo gtx rfi 2002, the engine was rebuilt, the first time everything seemed to go well it started and everything was working perfect then it didn't want to start anymore. It has a new battery and with 13 volts, I checked the spark and it is present too, I measured the fuel pressure and it is at 58 psi, I checked if the valve had stuck and everything was fine, I also measured all the sensors guiding myself by the manual and they all had the correct parameters. I had the injectors rebuilt and I haven't been able to start the engine again either. Please any advice you could give me? Thanks in advance.
