Sparks from where? Is it electrical like a loose wire or wire that has become bare? Is it fuel sparks? In any case sounds dangerous to people or electronics of the car at a min.

My ninja is losing power when i get into it. Idles great on all 4 but when i get going it loses power and seems to be just running on 3 cylinders. I have change spark plugs and wires and that didnt help....


Test the Coils . The coil produce the high voltage for wire plugs+spark plug+motor. If the coil is defective you ignition system can be wrong. see the diagram attached.

My 89 jeep cherokee won't. Start it will turn over


what motor? is the coil producing spark?? If so, check the fuel pressure, if the fuel pressure is low drop the tank, repace the pump and also replace the filter (located on the frame forward of the tank). If the coil is not producing spark, check for shorts or opens in the circuits as well as the IGN fuses. If there is NO fuel pressure at all check the fuel pump fuses and make sure the fuel pump is plugged in and there are no opens in the circuit

My car 1996 is 'missing' as I drive it on the road, is it the spark splugs that need to be replaced or something else?


The Engine can have misfiring due to fuel or firing issues. So check if there is problems in the fuel as if there is even residue or water on the fuel the firing can stop and produce the misfiring. Also the second point to be noted is the timing of the spark. if this is out of the correct settings then it can produce the irregular firing. Also the Spark plugs, the gaps on them and the HT cords and the HT coils must be checked if the spark is bad.
Finally the settings of the valves, the exhaust system can also produce misifiring.

I have a toyota cressida gli 6 1989 ,has spark and fuel,motor swings but just wont start


Where had you checked spark first? Is the distributor turning? This can be checked by removing the distributor cap and making sure the shaft is turning as the engine cranks. Have you checked that there is spark at the plugs? The ignition coil could be weak and still produce some spark but not enough to start the engine. Be cautious of all rotating belts and pulleys around the engine while working under the hood.

Replaced motor mounts, still virbrates like before replacment. mounts were from the factory.


Vibration can be caused by other things than motor mounts. An engine misfire could cause it. A bad cylinder (or valve or piston or spark plug) could cause it. Even a bad alternator can produce vibration. Injector could be a problem - have the engine checked by a qualified technician. Replacing parts can get expensive and an incorrect diagnosis won't help with the problem or cost.

No spark goin to plugs


1. Check the ignition coil. It must produce a good
spark at the distributor contact.
2. Check the distributor cap, and the rotor for carbon
deposits. This must be cleaned.
3. Check the spark plug cables for cracks, it may
need replacement.
4. Check the spark plugs. It must produce a bluish
spark. Otherwise, this must be replaced.

I have a 99 automatic V.W. Jetty, it vibrates a lot when is park, drive, or reverse, and also wile accelerating. I have a loss of HP, and sometimes my engine smokes from burning oil leaking on my engine....


Sounds like you have a lost, or weak cylinder in the engine. A compression test and, or a leak down test with confirm the condition of the engine.

1995 altima , 16 valve: no spark going to motor


I would be leary of the crank position sensor as these pre OBDII types are mounted in theupper transaxle bell housing. I would check for diagnostic codes and possibly using a DVOM meter check for an A/C millivolt signal to be produced out of the sensor while cranking the engine.Codes 11 and/or 34 present could further support there are issues with this vital sensor needed to produce spark.
