The computer is not receiving a signal from the crank sensor mounted near the harmonic balancer...without the signal from this sensor...the engine will crank but no spark....check for the sensor to be good and also check that the wires going to the sensor is good...you'll probably find bad wiring...unless the sensor is physically damaged......

I have Nissan Altima and oil is coming into the intake manifold and smoking too


The valve cover gasket seals are probably old and brittle and they are not sealing in the oil. This happens to most vehicles as they get older. With coil on cap plugs, oil will fill up the spark plug tubes and it will start to missfire. New valve cover gasket seals are probably needed

I would like to know how to change the spark plugs on the 1999 Isuzu Rodeo 3.2 liter


unplug the connectors for the ignition coil packs, then unbolt coil packs, remove coil packs (all 6 are interchangable) then remove and replace spark plugs. There is a row of three coil packs behind the oil fill cap on the valve cover and three on the other side.

96 Z71 new coil,ignition modual,plugs,wires,cap&rotor,spark from coil,no spark at plugs


Hello: Remove the distributor cap. Check the rotor, see if there is a black spot where the metal piece makes contact with the carbon stick out tha makes contact with the coil. Did you replace that piece when you replaced the coil, it should have come with the new coil? Also did you reinstall the ground strap that was under the coil and went to the stick-out that the black connector plugs into the cap?

92 civic engine stalled while driving; fuel pump works; replaced all plugs seeing some oil on old ones. only one plug fires; is coil still working? or the distributor? haven't checked fuel...


Hi,
Check the ignition distributor cap and clean the electric contact points it might be already dirty.

if one has a spark that means your ignition coil is still okay. Remove the whole cap and check the inside part and clean it, use emery board.
Check also the high tension wires( spark plug wires ).
Hope Fixya helps you!

I have a 1999 mazda 626 lx 2.0 the car ideled rough with ac or defroster replaced front and rear motor mounts,now it idels rougher and vibrates the car.


These cars tend to have bad spark plug wires, they will arc where the boot goes down into the valve cover.Check to make sure there is no oil in the spark plug well,if the is you will need to replace valve cover gasket and orings.Souds like you need a new set of plugs and wires.Look for corosion where the wires connect to distributor also as you may also need a new cap and or coil.

I have a 1985 s10 blazer .. i drained the oil and replaced the plug, and replaced the oil filter .. however, i am unable to remove the oil fill cap. it does not pull out nor unscrew .. it does hand...


If you have any other fittings on the valve cover (pcv valve, breather tube etc) you can put a hose into the valve cover through that hole and fill it. (slowly...most have baffles inside). I have seen engines filled through the dipstick tube also (takes forever though).
Once you get oil in there, bring it to a shop and have someone show you how to get the fill cap off so it is easier next time.

Possible bad ignition coil and valve cover gasket


No start on 97 dodge intrepid. I Know that Coil pack is Below Valve cover and Have repaired Numerous Ignition coils due to there becoming Oil soaked , the oil will gather dust dirt and thus Insulating ( Retaining Heat) i and this Causes them to Over heat and Fail , in short Burning them out. I say this Because of your Mention of it as a symptom. you must first Determine if it is getting spark ,have someone Crank Engine over While you are Holding the Spark plug wire 1/4 inch away from coil tower (TERMINAL) do this to all 6 if no spark at any of them ,that coil could be bad (Most Likley), If all Have NO SPARK then it is One of the fallowing,,

  1. Cam Sensor
  2. Crank Sensor
  3. Ignition control module
If Control module is wet with Oil most likely needs replaced some Parts stores can test coil and Modules.

NOW if you have Spark on All 6 Cylinders Check for fuel delivery, Do this at the shrader Valve on the fuel rail,(LOOKS LIKE AIR FILL VALVE ON WHEELS) Simply remove cap turn key on for 5 seconds then turn it OFF Depress the Stem at shrader valve If you get a Good SPRAY of FUEL upon doing this 3-4 times then you have Fuel Pressure !!!!WARNING !!! Test Equipment is Recommended for all Procedures but their certain steps to take if you don't have a DIGITAL VOLT METER or Fuel Pressure tester. I Hope this helps you with your Diagnosis od the problem. Have A Good Day

I believe that year had distributorless ignition, instead it uses a form of coil on plug ignition system.

If you open the hood, stand at the front of the vehicle. Look to the left side of the engine, around the bottom of the valve cover (The valve cover is where the oil fill cap is. The oil fill cap is on top of the valve cover), at the bottom of the valve cover on the left side you will see a series of humps. Those series of humps is the coil packs, the coil packs are all in one long piece held down by three or four bolts.

Take out those bolts, gently pry up at the ends of the coil pack and it will eventually come out. You'll see on the bottom side the spark plug boots are attached to the coil pack. After you get the ignition coil pack off, you will see the spark plugs under where the coil pack came from, the boots on the coil pack sit directly on the spark plugs.
