Question about 2001 Chevrolet Silverado 1500
Truck was cranking over fine ,i did notice my lights would dim sometimes and then come back for a couple weeks,but truck always started went to the dump ,went to start truck to return home nothing ,everything as power but will not ,crank over,no sound what so ever from the starter.
You have power where at the starter ? Heavy positive cable or the control wire at the solenoid ? Is the truck manual or automatic trans ? Free wiring diagrams here http://www.bbbind.com/free-tsb Do you know how to use a wiring diagram for testing electrical circuits ? How to use a DMM - digital multi-meter ? Enter vehicle info. year , make , model an engine size . Under system click on engine ,then under subsystem click on charging system . Starter circuit is the first one under that system. Click the search button then the blue link. A lot involved here that could cause a no crank . Ignition switch ,crank fuse , park neutral safety switch for automatic trans . clutch switch for manual trans . Starter relay ,ign.fuse 40 amp , Heavy gage battery cable to the starter solenoid , an if you have B+ voltage at that cable doesn't mean it can't be bad . Corrosion will cause voltage drop , need to test while trying to crank the engine .
Starter Voltage Drop

VEHICLE RELAYS Operation Diagnosis your starter relay works just like this one in the video .

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech

That means there is a problem with the VATS System. This sometimes happens when the battery is disconnected for an extended period. You might need to do a relearn for the keys. You can get it done with the right scanner in 5 minutes, but there is a way to do it without one.
Turn the key to the start position, release it to the on position, then leave it on for 11 minutes, then turn it off. Repeat this sequence three times, and on the fourth try it should start if that was the problem.
