AboutTed Ritter Expertise I have more than 26 years experience as toyota technician, I will be able to answer most questions related to the toyota product line up to the present year models, I specialize in difficult to diagnose problems but when posting a question please keep in mind that some situations require the used of special test equipment and diagnostic procedures especially as the newer models become more technologically advanced, so without actually having the car on hand I may only be able to try to steer you in the right direction and in some cases may have to refer you to the toyota dealer but at least you will know what you may be dealing with. Please don't hesitate to ask any questions, I will have an answer for you in most cases. When posting a question keep in mind that I reside in the US, although I get questions from all over the world I may not have an answer for models that are not sold in the US, I will do a reasonable search to try to match your model to the US model,please refrain from asking about diesel powered vehicles, I have no information for them. In most cases I will not answer questions about major modifications of OEM components, engine swapping or aftermarket products,please post a question not a statement, please provide enough basic information such as year, model, what engine and if anything has already been done to fix the problem, the more information I get the more I can help without having to ask you more questions.

Question i have a 86 corolla sr5 and swapped it to a gts i have all the harness,cluster,engine,and so on ex the rear. my problem is i have no injector trigger i have battery voltage at the injectors. the injectors ohm out ok in spec. i check grounds and test tps i thought it might be the igniter or ecu but swapped them but i really don't know if they were good need help bad
Answer I'm assuming that you also swapped the ECM, check the ground connections for the ECM, check all the brown/black wires at the ecm connectors to body ground, disconnect the connectors from the ecm and check each wire for continuity to body ground, the computer switches the injectors on/off by supplying a ground pulse signal to them.
