Like I said it has fuel and spark and I have spun the darn distributor right around but it will not fire.
N eed to start with the basics. Sounds to me like you are guessing.
Unplug the coil power lead, (so you dont burn off your eyebrows) crank it over and look down the throttle bore. See if the injectors are spraying a cone shape pattern.
Maybe you have the wrong balancer and the TDC mark is in the wrong place, or it slipped, resulting in an innacurate static timing setting.
Verify TDC #1 by the piston stop method,slowly crank engine with a socket wrench, while feeling inside the #1 hole for the piston to rise to the top, then compare topDead center to the balancer marks, to see if it is correct.
Post back after you are done.
