LT1 Optispark/timing issues

[gEtyOpAPiOn]

it almost looks like vats ...well at first crank when cold all injectors spray 3 times at once then it goes sequential...but the spark should be consistent if your opti works then with the key on engine off if you plug and unplug the cam sensor on the opti distributor your should hear the fuel pump go on again ,,if it was wired with the pcm , if the opti dist had any moisture on it ,it may fog up the lens and then it wont spark ,you could kinda open the distributor cap and use a hair drier or just blow air while cranking the engine through the lil vent hoses ,but like i said make sure you have power while cranking and not only with key on
