Question about 1990 Geo Prizm
My geo prizm air intake sensor has no power both from the air filter housing and on the from engine mount by the fan. Could how do I test the ECM for trace the line for problem?
Use an electrical tester with a sharp point tip, and poke through the coating into the wire at every 5".
this is the best wat to test the wiring.
