Hi
In engine compartment check Mini fuse ECM1 20 amp also test for voltage pink wire at injector.
If you're not getting any spark at the coil in your 1996 Chevrolet Truck, and you have already checked the ignition module and fuses, there are a few other potential causes to consider. Here are a few steps you can take to further diagnose the issue:
Check the ignition coil wire: Ensure that the wire connecting the ignition coil to the distributor or spark plugs is securely connected and not damaged or corroded. It's also worth checking the distributor cap and rotor for any signs of wear or damage.
Test the ignition coil: Use a multimeter to test the primary and secondary resistance of the ignition coil. Compare the readings to the specifications provided by the manufacturer. If the resistance is outside the acceptable range, the coil may be faulty and need replacement.
Inspect the distributor pickup coil: The pickup coil, also known as the ignition control module, is responsible for generating the spark signal. Check for any visible damage or loose connections. You can also test its resistance with a multimeter according to the manufacturer's specifications.
Check the crankshaft position sensor: The crankshaft position sensor provides the engine's rotational position information to the ignition system. A faulty sensor can cause a loss of spark. Inspect the sensor for any damage or corrosion and test it using a multimeter if necessary.
Check the ignition switch: The ignition switch controls the flow of power to the ignition system. If it is faulty, it may not be providing power to the coil. Test the ignition switch for continuity and proper operation.
Diagnose the blinker issue: While not directly related to the no-spark issue, the loss of blinkers could be a symptom of an electrical problem. Inspect the turn signal flasher, bulbs, and wiring connections to ensure they are intact and functioning correctly.
