If you take coil wire loose from distributor cap and hold close to engine ground, engine cranking, does a spark jump? If it does, make sure rotor turns when you crank it. The pink wire at the coil goes hot with key on, that is primary voltage, use a test light, is it hot? That voltage comes from ecm fuse1--15 amp, check voltage with key on.
If sensor issue, my first thought would be the crank sensor. Just my opinion.
Sensor detects engine rpm, and piston position. It is integral with the distributor, not replaced separately.
Testing the sensor requires complete testing of the ignition system. Use a spark tester to check for bright,. blue spark. This is called secondary spark test. If weak or no spark, test the ignition coil for proper specs of primary and secondary resistance. If coil is good but no spark, suspect the crank angle sensor. My manual gives no further information on testing the sensor. It contains a light emitting diode and a photo diode. The lights are used to show up the slots in the rotor disc that has 360 slits in it.
It does not use a crank sensor. It could be anything in the ignition system including the coil, distributor, spark module, or even the cap and rotor. The components would need to be tested. You check the coil for power from the key switch and look at the cap and rotor first.
This engine uses a special flat cap and a standard rotor, right ? The spark comes into the cap and thru the rotor, then to the spark plugs. Have you replaced the rotor ? The spark can jump thru the rotor and ground thru the dist. shaft. Depending on where you are testing for spark, the coil could also be weak and not pushing the spark to the plugs.
First does the rotor turn when cranking engine?? possible timing chain is out or stripped gear..are you sure it has no spark??did you verify this with a high output spark tester ? did you spray starting fluid in the tbi unit ?
What about the magnetic pick up. This is the crank angle sensor reporting to the ECM and creating spark. This is known as the G and NE sensor. Just for giggles with the distbutor on cap off crank the engine and see if the rotor change postion with the engine crank. if it does the timing belt is good if it doesnt you will need a timing belt.
