quite possible, sometimes they go with no warning at all.

Make sure the battery is charged. An orange spark is a sign of a half dead battery or a bad coil.

Put a test light across the coil's electrical connector. Look for the light to flash quickly as you crank it. If it does but your spark doesn't correspond (spark is intermittant compared to the test light flashing), the coil is likely bad.

Good luck.

allright checked for spark using spark testor in between coil wire and cap, it's bright orange,tested electrical wires coming from MSD box to coil, flashes with spark pulse but blows test light bulb. battery voltage is fine still won't crank I'm thinking bad coil per large orange spark or msd box thanks

Those MSD boxes have been known to fail quite frequently. If you still have a good stock unit as a spare, swap it in.

Do yourself a favor and sell/burn the MSD crap and put nice OEM parts back on. After that pull codes and see if it leads you to a bad TFI or not.
