i have only noticed that there appears to be no spark when using the colortune?

so it's not the lead or the plug - have you put a known good plug in the lead and held it near the rocker cover to see if it sparks?

if there's spark there, it might have lost compression due to a blown head gasket or a burnt valve, but you've gotta check everything you can possibly think of checking to narrow it down....
