1991 Chevrolet Silverado 2500 Questions & Answers
Gm engine trouble code 43 trouble shooting
Code 43 is electronic spark control. ESC module is not receiving a knock signal from knock sensor. Check knock sensor/wiring, check ESC (parts store can check for you). That's what the book says to do. On my personal vehicle I got a code 43 and the problem was a bad oxygen sensor.
I have a 1991 chevy truck, I am getting no spark.
check to see if your truck has a crankshaft position sensor, its usually located behind the harmonic balancer or right near there, if the sensor went bad or if the wiring got messed up there will be no signal to the ecm telling the ecm when to send spark to the coil. the crankshaft position sensor is responsible for telling the computer when to fire the spark plugs based on rpm and timing. check the wires on the crankshaft position sensor, if they look fine, replace the sensor, hope this helps!
