Changed relay inside car the rear defrost stopped working long time ago preparing for winter. A few hours later go start car and it’s vibrating loudly excessive fuel when go back up drive block and it shut off. Then nothing. Hook automobile test to read ignition coil. Got ignition coil and no spark still. Changes spark plugs wires no spark and crank position sensor and relay in junction box new. Still no spark turn engine over.

Good morning,

When you crank the engine, does the tach on the dash read RPM? The needle should move up a little showing RPM. That will tell us if the crank sensor is working.

I attached a wiring diagram for you of the system. Check for power to the ignition coil connector with the key on. You should have battery voltage at one terminal. Check the fuse I circled for you as well.
