Default 90' 4.3 L won't start! Please help!

I have a 1990 blazer that just wont turn. I checked the starter, solinoid and ground to the battery. The battery is also charged. Any helpful tips?

what do you mean will not turn? as in; will not turn over engine or that it does nothing at all?

how did you test starter and solenoid? if you bench tested doesn't mean it is any good

did you check engine to frame ground? is it a manual or automatic?

OK Its automatic, it wont turn the engine, just one click, and yes it was bench tested. No I did not check engine to frame ground, can someone tell me where it is?

could be neutral safety switch... search for it here and it will show how to check it
bench testing does not put it under load, so it could pass but not be worth anything

did you try bridging the solenoid to see if starter would engage?

When key is turned to START:
  • If the lights do not dim at all as key is turned, then no power is getting to the starter. Cables/connections are dirty, loose, disconnected, frayed or broken.
  • If the lights dim to nothing as key is turned, battery is low, and/or the cables are in poor condition, or the starter has excessively high internal resistance.
  • If lights dim only slightly as key is turned, then starter is defective or worn (if it's turning very slowly).
if I remember correctly it is on the passenger side

on the solenoid there is two lugs that have wires connected. one is from the battery to the solenoid and the other is from the steering wheel

put your truck up on stands. turn key to accessories and take a screwdriver and bridge the two lugs. if the truck starts you have a bad solenoid

good
remember testing costs little or nothing
throwing parts at a problem can take the beer money away

Ok I think that may be my problem, the solenoid, but now is there a certian way the starter goes on? Because I hear a little grinding when I bridge the solenoid so I stopped. Im afraid to damage the gears.

was there shims when you took your starter out?

if not loosen up the starter, push it up tight against inspection cover and hand tighten both bolts, then tighten half a turn , going back and forth till snug
