Topic: Trouble codes.... need help!

[bluerunner]

 

I got 2 trouble codes one was self explanatory but the second one was #12 which say RPM NE or G signal to ECU- missing within 2secs after engine is cranked.

Vehicle is a 1988 4runner, 3.0

Thanks in advance

Could you be a bit more specific with "check grounds"

one of the most important things when running an electric fuel injection as you are, is taht the system is properly grounded, check grouns at block to cab, block to frame, ignitor to firewall, ect. also, clear codes by undoing the neg battery cable, drive for 5 mins or so, and re check the codes
