Motor turns over but no spark changed coil and crank shaft sensor

Well replace lots of coils but same with crank sensor on these trucks

• For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. To perform a complete test of the Camshaft Position Sensor and its circuitry, refer to the DRB II diagnostic tester. Also see the appropriate Diagnostic Charts. To test the sensor only, refer to the following: See: Testing and Inspection
• Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips.

1. Connect the positive (+) voltmeter lead into the sensor output wire. This is done at the distributor wire harness connector.
2. Connect the negative (-) voltmeter lead into the ground wire.
3. Set the voltmeter to the 15 Volt DC scale.
4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup.
5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts .
6. If voltage is not present, check the voltmeter leads for a good connection.
7. If voltage is still not present, check for voltage at the supply wire.
8. If voltage is not present at supply wire, check for voltage at pin-7 of Powertrain Control Module (PCM) 60-way connector. Leave the PCM connector connected for this test.
9. If voltage is still not present, perform vehicle test using the DRB II diagnostic scan tool.
10. If voltage is present at pin-7, but not at the supply wire:

1. Check continuity between the supply wire. This is checked between the distributor connector and pin-7 at the PCM. If continuity is not present, repair the harness as necessary.
2. Check for continuity between the Camshaft Position Sensor output wire and pin-44 at the PCM. If continuity is not present, repair the harness as necessary.
3. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary.

1. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. NOTE: If sync pulse signal is not present, replacement of the Camshaft Position Sensor is necessary.
