My 2001 chevy venture won't start, battery, oil, coolant ok should i check the starter or fuses?

Turn on the headlites....when cranking do the lites dim or does anything happen to the lites??? Does the car make any noise when trying to start??? if not you may have a bad neutral safety switch try moving the shift lever up and own while holding the key to crank...if its a stick make sure the clutch pedal is fully depressed as they have a neutral start switch attached to the top of the clutch pedal likage arm above the clutch pedal assembly sort of under the dash....follow the clutch pedal arm upwards to see it...make sure it is working and/or plugged in.
If all checks ok check the leads to the starter/solenoid could be loose and or may be a bad solenoid....I recommend replacing the entire starter solenoid assembly if that is the case...why replace 1 part if the rest is equally as old?
