  1. A lot can cause a misfire:
  2. Primarily fouled spark plug(s) or bad wire(s).
  3. also a corroded distributor cap or rotor. a vacuum leak,
  4. A bad or leaking fuel injector,
  5. Engine out of time and mechanical engine faults including Compression leaks and sticking valves.
  6. More often than not it is simply a fuel or ignition system problem both of which are fairly easy to solve.
Troubleshoot your ignition by first assuring that you have fire.



If the engine does not crank at all pull the coil wire off at the cap and set it within an inch of the tower and crank the engine. sparks should emit from this wire to the coil.




You can test each individual spark plug wire this same way by just unplugging it and arcing the spark. then pull out the spark plugs to examine them and replace as necessary (on a dodge use champion plugs). the cap can be removed (make sure to put it on exactly as it came off and put each wire back exactly as it was or it will NOT fire correctly). to check for fuel disconnect the line at the fuel rail on top of the intake manifold and turn the key to ON. this will kick on the fuel pump and should push fuel out of the line as the pump primes. if this test works but you still are not getting fuel to a particular cylinder(s) start unplugging injectors while the engine is running and make a note of which one does not change the idle as this is your problem cylinder. remember any ignition or fuel system fault will disrupt your fuel/air ratio and can damage the catalytic convertor and o2 sensors

My problem was hairline cracks in the distributor cap. Replaced the cap and the car runs fine.

SOURCE: my 98 dodge avenger wont start i think its the starter pleas help

Sounds like the solenoid not grounded if you try to start and all it does is click then the solenoid is not grounded and if it's built on to the starter which it might be you might have to replace the starter. Try cleaning the wires going to the starter before you buy a new they may be corroded.

SOURCE: 98 Dodge Avenger 2.5L V6 isn't getting any spark.

Do you mean it's actually grinding while trying to start or it just cranks & won't fire?If it's the latter,i've had to replace 2 distributors on my 99 2.5 because the sensor which isn't serviceable has failed.

Why did you change the head gasket Patrick,
Was the engine missing before you did this,or did you over heat the engine from low coolant?
If the miss was there before you may have burnt a valve,

The crankshaft position sensor may be the cause of the problem, or your timing belt skipped a tooth. Hope it's the sensor.

98 dodge avenger transmission problem


codes will verify if it needs to be pulled out. More than likely it will as the electronics are rarely the problem. The computer senses a indifference in the ratio between the sensors so it locks it in limp mode - 2nd gear.
