Failure Injection Corsa

Juan Carlos: I don't think I passed through a coil theme, if you say that you mediates in the injectors and only two were 12 volt, and the others did nothing, did you measure them with respect to mass? Or among the terminals, I mean that if a tip of the tester at the + connector, and the other to the mass of the vehicle, because if I am not mistaken, the ECU controls the injectors by negative, so you can find the tency of the battery in all, but the negative sign To compare well the data I have of the Corsa, greetings

Did you tried the CKP or figger of the crankshaft? I had a similar problem replacing and solved the failure.

Hello Juan Carlos,

your procedure has been correct, and the signal for the coils comes from the ECU, you must make it review, no relay comes, the negative signal leaves the ECU

greetings

Very good jerk Oliva Muñoz .... I think the same .... ready

Greetings, to add a data on the Corsa there are models that are handled in series, that is, two injectors are handled by a cable of the ECU, and the other two other cable, if I remember the most I think 1 and 4 and 2 with 3 the series injectors, you have to take this into account when measuring why we disconnect all the injectors and measure volts we will have a reading of 0 volts in two of them. Greetings.
