1998 Chevy Lumina wont start Ive changed the starter, timing chain and battery. Ingine not locked however when trying to start it makes a click sound like bad starter. Does anybody have any idea on what could be going on?

Looks like ignition current is not being available to fire the fuel/air injected mixture from the plugs. Remove the cable tip which connects TO any plug. Hold the cable tip to any metal part of the engine block or any part of the body where the metal is exposed(not painted). Ask a friend to turn the ignition for starting the engine(vehicle). If the cable tip produces sparks, then the induction coil is OK, but since you have stated that clicking sound is heard which is actually the relay's which tries to get the induction coil to generate high current required for producing the spark to ignite the fuel & air mixture in each cylinder, thus starting the combustion required to turn the engine & subsequently power. So check the induction, belt tightness and finally the "Distributor"in the sequence as stated and you will be able to diagose which one of the above are malfunctioning............sodeep

Could be an ignition problem. Try turning your key on so the fuel pump kicks on then cross the terminals on the starter with a screwdriver.

Check the battery cables

I have had the same problem with my 97 Lumina it is generally in the vats system unfortunately the only why to fix this is to go to the dealer it costs approx 500.00 they have to replace the module the ignition and rekey the car. Sometimes if you put the key in the on position for 10 min it will reset the key then it will work. The vats is the vehicle anti theft system. For some reason the car is reading that someone is trying to steal it and blocking the fuel for the car causing it not to start....
