Hi everybody, and welcome to my "stevenofpa" YouTube Channel! This video shows you what it's like to learn about the ignition coil wiring harness, and the ground connector ring terminal, and how a little bit of corrosion can cause a poor ground connection that prevents the engine from starting and running properly. You can see the engine wiring harness in this vehicle, and the individual wires, and the copper ring terminal, aluminum valve cover, coil, connector, volt meter, dvom, test, diagnose, inspect, clean, repair, fix, how to fix a poor ground connection, engine won't run, crank no start, cranks but does not start, engine code p0300 p300 p303, p0303, misfire, runs poorly, can't start, won't start, stall, smells like gas, OTHER KEYWORDS, chafte, chafe, short to power, short to ground, short, bad connection, wire damage, loose, corrode, corroded, corrosion, clean, dull, dingy, fuse, relay, fuel injector, spark plug, cop, coil on plug, primary, secondary, fuel system, starter, generator, alternator, battery, panel, fuse box, continuity, ohms, power, ground, plus, minus, red, black, wire harness, connector, test, This video shows you how the diagnostic procedure was taking place, what steps were followed, a DVOM digital volt ohm meter fluke 88 automotive meter voltmeter was used to diagnose the problem, by conduction continuity testing across wires, ohming them out, to see if there was continuity and or shorts to ground, shorts to power, or shorts between the wires, and luckily there were none, however a bad or corroded ground connection was found at the coil grounding wire connection at the bolt at the back of the cylinder head, so that was good so it could be cleaned and fixed corrected, repaired, but the terminal was ok and did not need to be replaced. also the fuse was tested, power available fuse test, pin tester connection using factory wiring diagram schematic with ecm ecu pcm control module engine computer terminal connector testing It's nice to know how to fix things so you can do it yourself, test, repair, shop, mechanic, technician, tech school, teacher, instructor, lesson, how to, fix, garage This car is similar to other GM and Chevrolet vehicles and even Hondas like accuras like civic, accord, cr-v pilot, fit and more like chevy cavalier, pontiac sunfire, geo prism prizm, chevrolet cruze, buick verano, chevy onyx onix, ~~~~~ Please post your questions and comments below, and Thanks for Watching.
