After a cranking session pull one of the plugs. See if it's wet with fuel or dry.

Hi Dave.

Thanks for the reply Dave. I will pull the new plugs and check. When I changed the old ones they were damp, with #1 & #4 being the worst. Also I am getting voltage at ICM harness, SPOUT connecter, and misc. sensors. Used NOID light on injector and OK. Thinking at first fuel issue tried starting fluid, not a bark. The only time we have had any sign of improvement was after tune-up it briefly, and I mean briefly, acted like it wanted to start. But then just dead crank over and over. I believe timing is correct. At o TDC #1 intake and exhaust valves up, rotor pointing to left of #1 distributor cap pin.
Thanks.

If you are positive you have spark, with a good battery hold the accelerator pedal to the floor and crank it. See if it tries to start or does start. Holding it to the floor while cranking will turn the fuel off to the injectors. It puts the computer in a "clear flooded engine" mode. If you have good spark, it seems you are getting too much fuel for some reason.

I thought of the same thing as well. Did not work. Just dead crank. Tested spark at coil wire to distributor and at plugs with calibrated spark tester. Blue spark. But that was before tune up. Will check again. Thanks.
