1995 astro, back to no spark again, have replaced most components including coil,distributor and pickup. Also changed computer. No codes at all
Any suggestions?

Are the plugs new? Are they firing in the combustion chambers? If a plug in the coil wire fires, that doesn't mean the plugs in the engine will fire also. I've had new sets foul on me in the driveway. Pull them(replace if they're old) and see if they're firing. You might be surprised.
