I'm going to purchase the BD3 scanner as suggested on this forum. I also read where the '96 Tacoma ECU isn't capable of displaying fuel pump pressure because it doesn't have a sensor for that function. It was said that a low fuel trim indicated no problems with clogged injectors or low fuel pump pressure. Can someone explain why that's the case? Would a high trim condition indicate a clogged injector or low fuel pump pressure? Thanks! Still learning!
