Woodstock's answers are good but he left out 1 other possibility. Since you don't mention whether or not the truck has ANY lights or if the horn works or not, the other possibility is that your battery cables may have too much corrosion on them causing your problem. Remove the battery cables starting with the negative terminal (the black one) and make sure it cannot touch the battery terminal. Next remove the red (positive) cable and make sure it does not touch the battery terminals either.
If you see some white gunk on either the terminals or the cables, you need to clean them. This can be done in different ways - use a solution of baking soda and water mixed in something you can dip the cable ends in and soak them until they stop bubbling. Then use a brush (preferably a wire brush) to make the inside of the cable terminal shiny.
Do this with the other cable also. With the battery terminals just pour some of the solution over them and follow the above procedure. You can also use cola soda instead of the baking powder solution.
Bottom line is that you want the cables and battery terminals clean and shiny. Reattach the cables to the battery (positive first) and tighten them down to assure good contact between terminals and cables. With an old toothbrush placing some petroleum jelly (Vaseline) all over the terminal and cable ends will help prevent this in the future.

I would start by looking at a blown fuse or perhaps a bad relay or maybe a broken wire! If not any of those not sure would say maybe the starter, but you indicated that your gauges aren't working which make me think of the items I recommended! Hope it helps! Good luck!

I got a 2001 chevy/silverodo c1500 new battery month old it was all fine i got in to start it an it all but it won't turn over it won't make a noise nothing from starter the fuses r all good

Do you have a volt meter ? How to voltage drop test starter motor circuit Here is a site for wiring diagram Enter your vehicle info.Year, make , model , an engine size. Then under system click on engine , then under sub system click on charging system (starter system is also under that ) Then click the search button , then click on the blue link . You can issolate the starter circuit at the starter relay in the under hood fuse box , to see which side of the circuit is bad , control or the load (starter) side . If you pull the relay out of the fuse/relay box an look on the bottom you will see four numbers 86, 85 & 30 ,87 .If you were to take a piece of 12 gage wire an jump where 30 & 87 plug into the fuse / relay box . And if the starter spins the engine over you just eliminated the starter , battery cables , ground circuit as not being the problem . This would indicate that something on the control side was bad , Park neutral safety switch , ignition switch . But before replacing parts some electrical testing should be done . Hope this helps an if you have an questions let us know .

Need to know where the wires go off starter solenoid

What make , model an year vehicle ? Most vehicles have a heavy gage red wire that goes to the positive battery post an may have smaller gage wire's that have fusible links , that power other thing's like ignition switches , fuse panels etc... an one on the S terminal that could go to a starter relay or park neutral safety switch ,then to the ignition switch . It just depends on what make , model an year vehicle

Where is the neutral safety switch located on the transmission and is there another switch that would keep the starter from engaging?

If it is an automatic it is part of the Range sensor switch on the transmission where the cable hooks up from the linkage.

1979. Why does the starter drag when I try to start?

Solution #1: Check the rest of the electrical system for the correct voltage, grounds, and wiring. Often, the starter is misdiagnosed as the culprit for electrical system problems when the problem really lies in some other area of the system.
Solution #2: Check your battery voltage and make sure it is sufficient to turn your new starter. Most starters require at least 9.6 volts to turn over correctly.
Solution #3: Check your battery cables and make sure they are in good shape. Bad cables will not deliver the full current flow needed operate the starter.
Solution #4: Clean the starter mounting surface. Most starters are grounded through the mounting block, and if there is excessive oil or paint on the block, the starter will have a faulty ground.
Solution #5: If your vehicle has a neutral safety switch, make sure it is operational. If this switch is bad or not properly wired, the starter will not operate correctly. You can check by attaching a jumper wire between the safety switch terminal and the main terminal on the starter. If it turns over with the key, the switch is either bad or wired incorrectly.

I have a 2002 polaris magnum 325. I put a new starter, ignition switch, relay that goes to the starter and a new battery. It will turn over, but won't start. The starter is engaging also. It will pull...

Since you can start with the pull starter, and not when you crank with electric starter, assuming this machine has electronic ignition it is quite possible that the battery lead in not making good contact with the battery and there is a big voltage drop low enough to affect the ignition system due to the high current drawn by the starter. Try cleaning and retightening both battery leads and the ground lead. Also check the power cable running to the ignition system. Also check for corrosion near the ground connection on the chasis.

The starter has been tested as good, but the car wont start, any ideas?

load test battery
check for tight, clean connections at battery
check neutral safety or clutch safety switch
check starter relay
check ignition switch
check engine and chassis grounds,

Four types of starter motor are utilized depending upon the vehicle transaxle and assembly plant location. Manual transaxle equipped vehicles utilize a conventional starter motor which consists of a yoke, an armature assembly, an overrunning clutch assembly, a solenoid, a commutator end cover, a brush holder and a pinion drive lever. Automatic transaxle equipped vehicles utilize a reduction type starter motor which has, in addition to the components found on conventional starter motors, a reduction gear and shock absorber assembly.
In the basic circuit, the solenoid windings are energized when the ignition switch is turn to the START position and the clutch start/neutral safety switch is closed. The resulting plunger and shift lever movement causes the pinion to engage the engine flywheel ring gear. This movement also causes the starter solenoid contacts to close.
With the contacts closed, the starter solenoid provides a closed circuit between the battery positive terminal and the starter motor. Because the starter motor is permanently grounded to the engine block, the circuit is complete and cranking occurs as soon as the starter solenoid contacts are closed.
When the engine starts, the pinion is designed to overrun and protect the armature from excessive speed until the ignition switch is released from the START position. With the ignition switch released, a return spring in the solenoid assembly forces the starter solenoid contacts open, breaks the circuit between the battery and the starter motor, and disengages the pinion. To prevent prolonged overrun, the ignition switch should be immediately released upon engine start-up.
