1996 Ford Explorer Malfunction - Ignition System
Question: New Ford factory remanufactured motor, less than 2 hours on it. Missing on cylinders 4 and 5 per code reader. checked the coils and all measure correctly on the primary and secondary. New plugs and wires. I didn't have a spark tester so I cliped my timing lite on each wire and intermittent indication of spark on cylinders 4 and 5. Under load tends to backfire. I am wondering if it may be the crank position sensor from the old engin. I cant find any information on setting the proper distance (gap) from the index area on the crank balancer.

Technican: Hi;
As far as I know the sensor is not adjustable. My first test would be a compression test. Sounds like they might of done something wrong when the engine was put together.You would probably have to do a dry and wet compression test to really see if its in the bottom end or the head. Most of the CKP sensors I have replaced on explorers is beacuse the sensor cannot pick up the number one cylinder there cause not starting You can check the voltage to it by disconnecting it and checking from the connector at the wiring harness to a good ground. You should be getting approximately 1.5 volts withthe key on. . Here's How To Get Guaranteed Solutions In Minutes
