Someone should positively verify spark, pull a plug, leave wire attached, ground metal body of plug and crank motor, look for spark........You can use starting fluid to start a motor in that condition, but I'd be REAL careful with that stuff, no more than a 2 second shot in airbox. I watched someone overdo that stuff once and when done there were 6 out of 8 connecting rods laying out of the sides of the block and oilpan had like 10 holes in it.
