1986 Toyota 4Runner 4 cyl Four Wheel Drive Manual 250000 miles
Hello. I have no injector control from my ecu. I can trigger the injectors by grounding their circuit at the ecu connector. My hall effect generator is able to cause the igniter to trigger spark at the correct time. (5*BTDC) The engine will start and then die as it burns what comes from the cold start injector during crank. From what I have read, the ecu will not trigger the injectors unless it gets a digital signal from the ignitor. I've replaced the three wires between the ecu and igniter. Code 11 is what I have. I have bypassed the tps portion of this code be jumping idl to e2 at the tps connector. I believe this should make it look like I want idle which would be a step in the right direction. I have tried another suspected good ecu with no change. Same for the igniter and the generator in the distributor. My fuel pump is good and my flapper door in the afm triggers it. My question is: What else does the ecu need in order to trigger injectors?
have the same problem?
