Solisito helps

A Toyota Pickup 89 Ay spark came to my workshop, I don't have a gasoline injection, I don't have a scanner, I get codes, I get 12 and 14 12 it is rpm If there are revolutions on 14 is a sign Igf no ay signigf my question is if this signal comes out of the ignition module acia the ECU and how do you measure this signal Munchas thanks for so help

Do you have current in the injectors?

If there is current in the injections, what does not arrive is the pulsation, that is, the computer signal

Rotation sensor test

Thank you Govi, I already check the distributor, it has 3 rapping coils bariable, they give me a good sign, check ECU their positibas and negative feeds and are correct but from the ignition module the signal IgF Asia the Ecu does not come out
