Question about 1997 Jeep Grand Cherokee
The jeep will turn as if its trying to start, but then it kills. If I give it gas while trying to start it will start. as soon as I release the gas it kills again can you help me.
Sounds like a crank sensor.
The crank sensor is usually mounted at the seam between the engine and the transmission. It has three wires: one will have 8V on it compared to ground when the ignition is ON, and if you measure the voltage between the other two wires you should see ii switch back and forth between 5V and 0.3V as you turn the engine by hand using a socket on the crankshaft bolt, again this is with the ignition ON. If you don't get that then the sensor is bad. You can read these voltages by using a very fine pin pushed thru the insulation of the wires to make contact with the conductor inside.
