Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello, thanks for posting
Have you checked to see if there is pulse voltage to the injectors, one wire on each injector should have battery voltage with the key on, next connect a test light, preferably a noid light that plugs into the connector, when cranking the engine the light should flash. If this happens it means the computer is turning the injectors on/off like it's supposed to. Let me know the result of this test and we'll go from there.
