I have no pulses in the GQ15de engine,

Hello colleagues, I have a problem with a Nissan car with an QG15 engine does not turn on and I have already tried all the components and I do not have 12v to the ECU and the truth is the electrical scheme that I have does not match the brain of this car, I ask you some tips to be able to solve it, what more tests should perform to have a spark? Because doing all the tests I already got pulses in the injectors thanks to a pulse tester but I have no spark. Thanks I will wait for your opinions

Check fuses and matrix fuses in certain ECUs when the uncovers on the card where the pins are marked all Ig1 and 2 etc. I hope it helps you something

What model is it is Japanese or original or national helm

Look my friend the car that year is
if it does not have a spark,
check the ECM reverse,

check
the computer feeds and land then
prove with a logic tip the camshaft sensor if it generates pulses and the crank sensor
all the measures have in the terninals of the ecm
