Without CKP sensor signal input, the ECM does not output the ignition and fuel injection signals. Fuel injectors are firing. I'm afraid it looks like the ECU is fried. The 3X CKP sensor's signal is used by the fuel injection computer to start injecting fuel. Here are some more specifics: The 24X CKP sensor is connected directly to your Chevrolet (Pontiac)'s fuel injection computer and bypasses the ignition control module. The fuel injection computer uses the information from the 24X CKP sensor to calculate This crank sensor is connected by a three pin weatherproof connector. These three wires are made up of power, ground and the signal wires. Before you can begin testing your Blazer Crank Sensor, you will need a multimeter to test the values at each wire. Because the crank sensor is located near your transmission bell housing, you can reach this The crankshaft position sensor (CKP) is usually a two wire sensor: a signal and a ground. The CKP sensor consists of (usually) a permanent magnent sensor that is mounted in front of a reluctor (toothed) wheel mounted to the crankshaft. As the reluctor wheel passes in front of the crank sensor, an A/C signal is produced that varies according to To check continuity at the CKP sensor connector, unplug connector. Turn ignition on. measure between pin 1 and ground, it should be battery volts. Between pin 1 and pin 2 should be also battery volts. Between pin 3 and ground should be about 5 volts.
