2000 Chevy venture won't start. I charged the battery all night and its up. A month ago replaced starter ( there is no clicking sound ). The gauges kinda flip around which seems unusual. Its just dead, I think I hear a litle noise, like maybe a relay or something is engaging. Was looking for other possible causes. I also checked all ignition fuses under the hood and inside passenger door.
First of all make sure the starter drive is not stuck out onto the flywheel (flexplate) teeth. If you could get under there and look or just loosen the starter bolts a few turns and shake the starter and listen for the starter drive to snap back, then it was stuck and you may have to shim the starter.
Next if that is not it, then check for voltage to the starter on the purple wire with the key on start. For the wiring diagram, click here. Also, if it's an automatic try holding the key on start and shifting through all the gears from low to park, and if at any point the starter engages except neutral or park then the neutral switch needs adjusting.
What would I be looking for for amps from starter?
If I need to shim what do I use?
Amps? I'd say no more than 150. Do you have an inductive ammeter?
Shims? Just about any auto-parts store sells gm starter shims.

I wouldn't be concerned right now about starter current amp draw since it appears that it is not even getting voltage to the solenoid. You can use a 12 volt test light or voltmeter on 15 volt scale to check for voltage to that purple wire with the key on start.
If you hear the solenoid click then make sure you have straight battery voltage at the big cable down there. As you can see in the wiring diagram, there is a fusible link, so to test that you would just check both sides of it for voltage.
sorry meant volts !
are there any other posssible causes.
If it just went dead once, look for something electrical left on. If not, either the alternator isn't charging or there may be a short draining the battery over time. You can check both, for a short, disconnect the negative battery terminal and place a voltmeter or test light inline with the cable with the negative test lead on battery neg post and pos test lead on disconnected cable. With everything off hood closed and doors closed there should be no light or reading. If there is remove the fuses one at a time untill the drain goes away and then inspect everything on that fuses circuit to first make sure it works and then for a short.
To test the alternator get a total battery reading across the battery with engine off, start the engine rec it up to 1,500 rpm and the voltmeter should raise slightly above what the voltage was when it was off.
i couldn't get a " light test " reading on the purple wire at the starter and I made sure it was grounded good casue I got a reading of the HOT terminal, but the starter is clicking once when I try to start it, doesn't that indicate power to starter and possible a bad starter? I did pull starter and have it tested and they said i need an ignition switch, not sure if they are right cause again I had a click coming from starter.
