No Start

The knock sensors only retard timing. They generate an electrical signal in relation to a particular frequency when the engine is knocking or pinging. If they go bad they can't generate that signal to the computer. They would act like they were unplugged, trip a code most likely but couldn't hinder the ignition from firing. When they fail the problem is the ignition does act normally and when it starts to ping or knock it keeps doing it.
MAF signal to the computer shouldn't affect ignition (shouldn't). The MAF signal should be used for injector pulse width adjustment (rich / lean).

Took my car to "Cutting Edge Automotive" in Santa Fe, NM, took them 3 hrs. and they figured it out! Apparently in 1999 Volvo changed how they wired the Crank sensor into the ECU. If I would have crossed the wires instead of matching the colors dam car would have started, who would have known? Oh well at least its running again. A huge thank you to everyone who tried to help, it really was very much appreciated, Kent.
