04 chevy no spark
My 04 suburban has no spark, I changed
crankshaft and camshaft sensors, ignition cylinder
and still nothing.
assure the strap connecting the battery to the engine is free of corrosion and can make the amperage requirements~...basically clean your battery with a wirebrush...rinsing with plain water~
The coil may be bad, check for cracks & carbon tracks, it also can be tested at Auto Zone.
