Question
99 tahoe won't start.  It turns over good, it even tries to start but it won't start.

Answer
Hi Ed.... well it could be all kinds of things causing that...first see if you may have flooded it...do you have good spark? do you have good fuel pressure? try holding your foot to the floor to clear flood and turn over...if it starts you will need to change the oil as the fuel will contamanate the o2 sensor causing the computer to read wrong...if it doesn't go check fuel pressure and spark...if fuel pressure down check filter see if plugged, if spark not good check cap and rotor as these are known to go bad....hope this helps
