1998 jeep will not start

When you tightened the battery connection you may have twisted the cable on the starter and shorted it to the solonoid lead causing the starter to engage . Check the connections on the starter and make sure there are not touching each other. Hope this helps.

check battery connection.tune up,fuel filter,coils.

If you turn the key to ON position and its not cranking at all,then its battery fault.If its cranking but not starting at all.That means the starter is also getting power.So if its cranks but not start then there are few possibilities to be checked.But if its not craning and no noise then battery and starter are to be checked.In other case :----

A jeep that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the jeep. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the jeep starter. The starter gets power from battery to start the jeep. If the starter is faulty then it will not let the jeep to start. Also check and confirm that there is fuel in the jeep. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the jeep. If the jeep starts momentarily, then there's a good chance the fuel pump is not working or the jeep is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

The starter is most likely the problem,tap on the starter lightly with a hammer while trying to start the engine,dont get run over doing this it will take two people,if the engine starts,the starter needs replacing.

;check battery to body; and engine earth cabel if ok check starter connections. with a volt meter check battery volts when cold should be about 12.6 volts now crank engine over note reading should drop about 1 volt. if it drops alot more you will have a starter fault think you will find a problem with earth cabel i assume you have correct oil grade in engine

Check your plug going into your coil. The black wire that goes to that plug had gotten loose and was not making contact with the coil.

You need a new battery. The lights only take about 10 - 15 amps, the starter takes 200 - 400 amps, Replace the battery and all will be well

check the coil with key on, grounds and power wires,

COULD BE THE TPS DROPPING OUT

This is basic, but first off, try to shift it into neutral, and try to start it. It is easy for the linkage to get out of adjustment, where it thinks the jeep is in gear. If that does not work, make sure you have battery power to the ignition and starter.
