SOURCE: engine not sparking from plug changed battery

Check the kill switches including the side stand switch, with an Ohmmeter. Check the fuses. Check the wiring harness. Are all wires clean and with a solid connection? Any abraded wires? Check the operation of the ignition switch with a volt ohmmeter. Is the bike in neutral and the neutral light is lit up?

If still no spark, get CDI system and coils checked at the dealers shop.

Please rate this answer. Thanks!

Troubleshooting engine

Yes you are heading in right right direction. Check to see if there is spark out of coil. Spark at coil means replace distributor or rotor. No spark at coil replace ignition module or crank sensor good luck. Oh yea crank sensor is cheaper i would try that first if there is spark out of coil.

Spark at plugs no start

If an engine has a coil-on-plug ignition system with no plug wires, remove one of the coils from the spark plug and insert an old spark plug, a spark plug tester or a screwdriver into the end of the coil. Ground the spark plug or plug tester to the engine, then crank the engine and look for a spark.

Crank, won't start problem. I checked the spark plugs on Jeep 98. Looks good. Could it be the crank sensor or starter coil?

Yes it is very much possible.But there are many other possibilities too,including starter and spark plugs issue.

If your engine cranks normally but will not start because it has no spark, or it stalls and won't restart because it has no spark.

You can also do a test to confirm the problem .The procedure to do the test is as follows:---

If your engine has spark plug wires, disconnect one of the plug wires from a spark plug and place the end of the wire near a metal surface on the engine. Then insert a small Phillips screwdriver into the end of the wire (the plug boot), or a small bolt or nail to provide a conductive path. Then crank the engine and look for a spark to jump from the screwdriver, bolt or nail in the end of the plug wire to the engine. If you do not see a spark, there is an ignition problem.

OR-----------

If your engine has a coil-on-plug ignition system with no plug wires, In that case remove one of the coils from the spark plug and insert an old spark plug, a spark plug tester or a screwdriver into the end of the coil. Ground the spark plug or plug tester to the engine, then crank the engine and look for a spark. No spark indicates an ignition problem.If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).-----------------

Jeep cranks but no start:----------------

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 car starter. The starter gets power from battery to start the jeep. If the starter is faulty then it will not let the car 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 car 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.

Changed fuel pump. getting fuel to engine. but will not start.

Check for spark. Maybe a crankshaft position sensor is bad or a module.

Secondary Spark Test This spark tester looks just like a spark plug, attach the clip to ground and crank the engine to check for spark 91052p10.jpg
This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems 91052p11.jpg
Attach the clip to ground and crank the engine to check for spark 91052p12.jpg
This spark tester is the easiest to use just place it on a plug wire and the spark voltage is detected and the bulb on the top will flash with each pulse 91052p10.jpg
The best way to perform this procedure is to use a spark tester (available at most automotive parts stores). Three types of spark testers are commonly available. The Neon Bulb type is connected to the spark plug wire and flashes with each ignition pulse. The Air Gap type must be adjusted to the individual spark plug gap specified for the engine. The last type of spark plug tester looks like a spark plug with a grounding clip on the side, but there is no side electrode for the spark to jump to. The last two types of testers allows the user to not only detect the presence of spark, but also the intensity (orange/yellow is weak, blue is strong).
  1. Disconnect a spark plug wire at the spark plug end.
  2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine.
  3. Crank the engine and check for spark at the tester.
  4. If spark exists at the tester, the ignition system is functioning properly.
  5. If spark does not exist at the spark plug wire, perform diagnosis of the ignition system using individual component diagnosis procedures.

Ignition Coil Testing
  1. Remove suspect coil.
  2. Disable fuel pump by disconnecting inertia switch electrical connector.
  3. Reconnect the ignition coil electrical connector to the coil.
  4. Install spark tester 303-D307 (D81P-6666-A) or the equivalent.
  5. Crank engine while observing the tester.
  6. If a blue-white spark is not observed replace coil.

Removal & Installation To Remove:
  1. Remove the air cleaner outlet pipe if interfering.
  2. Disconnect the connector from the ignition coil. coilconn.gif

  3. Remove the bolt from the ignition coil. coilbolt.gif

  4. Remove the ignition coil on plug.
To Install:
  1. Install ignition coil on spark plug.
  2. Install ignition coil bolt. Tighten to 10 Nm (89 in. lbs.). coilbolt.gif

  3. Reconnect the ignition coil electrical connector. coilbolt.gif

  4. Install the air cleaner outlet pipe if removed earlier.

Wont start

is the your car engine cranking when you try to start, first check spark plugs ignition coils, remove one ignition coil and spark plug fix the spark plug in to the ignition coil then connect ignition coil to wiring and keep spark plug body touching on ground of engine head mettle parts, ask some one to crank engine then you can see is the plug sparking or not, do the same way to all the coils and plug otherwise you have to buy a ignition spark tester, is the all the coils and spark plugs are OK then check the fuel pump, it's sitting in under rear seat, before that do one thing disconnect oxygen (O2) sensor wiring and crank engine, the thing is if your oxygen sensor completely dead fuel pump will stop working, if engine start after disconnect O2 sensor, replace new O2 sensor, otherwise need to check fuel pump relay fuse and fuel pump. is this information helped you? please vote me and give a comment.

The engine is cranking want start

check for fuel .? spray staring fluid into throtle body then crank if engine runs then stalls you have fuel related problem ( fuel pump) if no start you have ignition problem ( coil or distributor check for spark use a screw driver insert into spark plug wire at spark plug end hold about 1/4 away from gronded engine and crank engine see if spark jumps gap if no spark could be coil or crank sensor

Doesn't start

I assume that when you started the car the starter was running and the engine was cranking.
Remove the #1 boot from spark plug 1. Insert a screw driver to the booth, bring the screw driver near the engine body (about 2 mm) and let someone start the engine. If there's no spark, replace the ignition coil. If there's a spark, check the ignition timing with a strobe light.

Before changing the ignition coil, make sure that the wires connected to it are alright. Remove them from the coil and switch on the engine. Measure the DC volts from the wires. You should get a 12 volts reading between them.
