ECU shouldn't give much power out? except maybe for TPS?
the ECU grounds the injectors.
it receives a voltage/signal from the O2, the AFM/MAP, but it should send out voltage to the temp sensors. (and maybe 5V to the AFM/MAP?)
for dizzy, the power comes from the ignitor? and ECU only receives a pulse or grounds ignitor to fire? or does it send pulse to ignitor?
anyway, check the temp sensor power out first? then MAP?
