    What problem do you have to start with, does the vehicle not start? And just what are you touching with this screwdriver?

The only reason it would spark is if it was getting a better ground than the one it has (shock hazard). Check your battery to body ground. I suspect it may be corroded. Also check your engine to body ground for good measure.

Replaced battery on a 2005 land rover ls3. Now it cracks but wont start. Do ypu think it is the inertia switch?and if so then where is the inertia switch on a 2005 land rover ls3?

Why would it be the inertia switch? Did you hit something?

Check the computer for codes 1st. You don't want to be spending money you don't have to.

Are you sure you are getting gas / spark / air? With out these 3 basic components, you will not fire the engine? Did you check all your fuses incase you blew one when re-installing the battery?

The proper way to remove a battery from a NORMAL car is to remove the NEG cable first then the POS. The re-install is reverse, on the new battery place the POS cable on first then the NEG cable. If you did not do this, you may have caused a spark and a surge in the electrical system causing a fuse to blow out. I hope for your sake IF you hooked it up wrong that you did not blow the ECU / ECM.

Mercedes 1975 280S points with no spark what is wrong points are new

You understand that the points are the ground point for the primary circuit to the ignition coil? When the distributor shaft turns and the points break contact, that cuts the primary current to the coil. When that happens, the secondary windings in the coil are induced to generate high voltage through the high tension cable out of the coil.

Are the points set to the proper opening gap? Here are a couple of checks you could make: With ignition key on, not start, the small wire to the coil's + terminal should have voltage-check with a test light or voltmeter. Or if you don't have a tester, take off the distributor cap and the rotor. Turn the engine till the contact points are opened. Or you could prop them open with a piece of cardboard or thick paper between the contact points. Turn the ignition key to on, not start. Take a small screwdriver and hold it on the moveable arm of the contact points set. Slide the screwdriver down and touch the base of the points set. If the primary circuit to and through the coil is good, touching the (grounded) base should cause a small spark at the screwdriver tip.

If you have current to the coil, but no spark, it could be a bad coil, but don't forget to check the secondary ignition: From the coil high tension wire to the distributor cap to the rotor to the plug wires and to the spark plugs. All of them need to be checked.

If I owned a car with mechanical ignition points, and planned to keep it more than a year or so, I would buy an aftermarket electronic ignition set up for it (like a Petronix kit, for one). I think you can buy them for under $100, and you will never have to bother with those old points again.

I have a 91 chevi silverado and when i connect the positive the battery starts to spark alot

Some sparking would be normal if you have the neg. already hooked up but it is best practice to connect the positive first.

With the negative side not connected nor touching any other metal surface, there should be no sparking.

Then connect the negative side. Again, always disconnect the neg. side first and connect the neg. side last. I think you will have less sparking going on then.

I just replaced my alternator but everytime i try to connect the neg cable it sparks like if wires are touching but there not

Is the ignition key on? are there any accesories on?
sometimes you will gt tiny sparks when making the connection, as long as you installed alternator correctly. Just make the connection and the spark will stop after a permanent connection at the battery..

If its a new starter check and see that the wires are hooked up right, could be time for a new starter, or starter relay on the fender well, or the ignition switch is bad.

2001 Ford Focus stopped running while i was driving and wont start. Makes a churning sound but no power is going to engine. I changed the ignition coil, still wont turn on. Any suggestions?

Can you explain more so I can help. What do you mean still wont turn on, engines doesn't start or starter motor doesn't turn. Have u taken out a spark plug and connected it to the cable put the end of the spark plug to a ground and make someone turn on the engine for a few seconds you should see some blue sparks. Carefully use gloves. If no sparks, spark plug is bad next thing to check instead of putting the spark plug in the cable put Philips screwdirver put the screwdriver near a ground not touching about one inch make someone turn the engine for a couple of second you should see the spark jumping from the screwdriver to the ground, If there are no sparks ignition coil or spark plug cables are not good. But u say u changed ignition coil so maybe your cables are not good. There is a connector near the ignition coil disconnect it and turn ignition switch on measure the voltage you should have in between 12vdc + or - .5 vdc if no voltage present there is a blown fuse, Check for it

I think that the coil packs has installed wrong because you said that the problem started when you replaced them... so i think you should re-install.
