Hello.

I am having issues with my 88 Toyota Supra with a 2jzgte automatic swap. The engine came from an Aristo. It was running fine, then under idle it started to die. Now it just starts up and immediately dies. I checked the diagnostic code and I got codes 47 and 78. Can anybody help?

Thanks,
Brian

Looks like a fuel pump and throttle sensor signal?


Is it possible the fuel pump died 1st and then caused the throttle sensor error?

Reset your codes and see if only 78 comes up.
