HELLO I CHANGED MY STARTER WHEN I CONNETED THE BATTERY I REALIZED I HAD THE WIRES CROSS THERE WAS A SPARK NOW MY CAR HAS NO POWER GOING TO IT ITS LIKE I HAVE A DEAD BATTERY I CHECKED ALL FUSES INSIDE CAR I DIDINT SEE ANOTHER FUSE BOX UNDER THE HOOD CAN YOU HELP ME 1997 GMC JIMMY 4.3

Make sure the plugs are all tight.

Check the battery.
When battery dies these problems can occur first check the battery is in good condition..

Check the fuse box. The main fuse to the starter might be blown.

could be the ignition coil (you can check for a spark on the ignition coil by holding the power cable coming out of the ignition coil close to an unpainted metal part of the frame. if the ignition coil has spark, then change your spark plugs (if the tips look burnt, crusty or oily), spark plug wires and distributor/coil packs.

You might have a bad connection. Check your ignition fuse first. It may have blown. Make sure the battery terminals are on good. You should see a spark or hear the current when you take the terminal and hit the post. Listen and look to see if the battery is holding a charge. If so, you need to check the wires that go from the battery to your starter. Make sure they are getting current off the battery. You can test then with a voltage meter. Make sure the battery post and terminal ends are cleaned. Your battery, if new, should be given off over 12V or around it. Patricia, If it is not the fuse, check the wires. Make sure they are on the battery correct and the wires are tight. If you have a question, please let me know. I am here to help. Feel free to write back Patricia. Thanks for choosing FixYa.

There are some possibilities which you will have to check in this case:--

1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.

2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.

3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.

4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.

5) If all the above possibilities mentioned above checked out OK/perfect then it's a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.

Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

If there is one it should be on the passenger side in the back behind the panel should have a tag that says fuel pump reset, and also did you connect the wires correct on the pump, do not cross them, should see a + & - on the pump

You have 2 wires touching somewere.  Possable burnt together. Check the wires at the soleniod one is ground one is hot from the switch. remove the wires hook up battery with a 12vdc test light or volt/ohm meter ck for voltage on the wires. find the hot one and trace it thru the harness cut any ties or remove and coil like cover you should find the spot where it is burnt together or just rubbing. 

sounds like a dead s wire to the starter if you can jump it across thers no power to s wire

I suspect that your spark plug wires or your distributor is going out. Check your spark wires and distributor. To do that take out #1 spark plug wire from the spark plug. Next take out your spark plug then put it in the spark plug wire. Then turn on car and take a look at the spark plug to see if it's getting a spark. Do this with all the spark plug. If it is your spark plug wire I would replace all of them.
