End provided a 2000 Silverado Has a Damaging Ignition Coil
Your 2000 Chevy Silverado Motor lorry Testament doing elder problems starting up provided still one of its ignition coils is not working properly. End not, on the other hand, automatically assume an ignition coil is the difficulty. Gaze and proof all other components of the battery and ignition manner before going to the coils. Once there, you must check Everyone coil individually for its Correct resistence to fix upon if replacement is basic.
If they are all in good condition, remove the fuel pump relay to disable the fuel system before proceeding.4. Disconnect a spark plug wire from its plug (after reconnecting the battery) and connect a spark tester to the plug wire's boot. Connect the tester's clip to a metal ground on the truck, such as a metal bracket or bolt.
It's doable that a loose or corroded clamp is causing the dilemma, rather than an ignition coil.
2. Disconnect the battery cables and connect a load tester to the battery. Using the tester as per its directions, keep going a load on the battery for 15 minutes; whether the voltage drops below 9.6 volts, the battery is evil.
3. Disclosed the fuse box and observe all of the fuses related to the ignition system.
Instructions
1. Flash over the clamps on the battery cables and beget positive they are Disinfected and tight approximately the terminals.5. Crank the engine with the ignition key and observe the spark tester; it may be easier To possess another person crank the engine. The coil is good if the tester produces a bright blue spark.
6. Repeat the previous two steps for each of the ignition coils and spark plug wires.
7. Disconnect the spark plug wire if no spark appears and connect an ohmmeter to both ends of the wire. The wire is bad if the resistance exceeds 30,000 ohms.
8. Disconnect the electrical connector from the ignition coil and connect a voltmeter to the two primary terminals at the coil's electrical connector. This primary resistance must be approximately .1 ohm.
9. Connect the voltmeter to a primary terminal and the secondary terminal on the coil's other side To gauge the secondary resistance, which should be between 5,000 and 25,000 ohms.
