SOURCE: 95 Jaguar XJ6 will not start and No codes present?

During cranking @crk sensor u should see up to 1 ac volt. Also if cam position sensor is @ fault u may not get a code, internal fault. Cam sensors are not availible,but rebuild kit is availible. The engine has to be set to top dead center aligning mark on crank pulley & tab aswell as mark on cam sensor itself.

SOURCE: cranks, but no start. spark and fuel good, no

cam timming is possibly out due to gear reduction set up in heads
suggest remove rocker covers and make sure cam lobes are in this possition as well as all other timming marks luckily these engines (V6) are free wheeling (wont bend valves) set up like pic below

Hi there, i have placed new coils and spark plugs also got new air-flow meter sensor new battery and car does not crank over please help


Hi does the motor turn with key but doesn't start?, If so take a spark plug out and replace it back into the spark plug lead and earth it onto a steel part of the body(make sure it's touching something steel). Have somebody turn the key to see if your getting spark. If you have spark then you have a fuel blockage but if you don't have spark but have new coils and battery then it could be a loose wire in the coil harness meaning electrical......
You say car does not crank over, If you mean you turn the key and motor doesn't turn then it's electrical, so no spark OR motor doesn't turn you're better off getting an auto electrician but if you have spark it's fuel problem and you need a mechanic... Sorry and good luck......

My dodge durango is not starting..fluids are good, battery is good, fuses, spark plugs is good. seems its not getting a spark or gas.


First you have to determine weather you have a FUEL problem or (ELECTRICAL)Spark problem ??

Pull the coil wire off or a easy to get to spark plug wire, Lay it close to were you pulled it off of (Do not hold or touch you may get SHOCKED) and crank motor (need two people) look and listen for a spark, if you see or here a spark, then go to next step which will be to check for Fuel (gas). Be very careful when checking fuel, as most lines are under pressure and may cause bodily harm such as BURNS to EYES and SKIN!! Loosen or pull the inlet fuel line off and put rag over line. Some fuel injected vehicles have a fuel rail the has a valve that looks like a tire valve. Put a rag over this valve and push it in with a small screw driver and have someone crank motor a couple of times to see if fuel is coming out.

If NO Spark---Could be a lot of things Points (older vehicles) Modules, Coils, Crank Sensors, ECT......

If NO Fuel---- Could be Clogged fuel filter, Fuel Pump, Fuel pump Relay, Fuse, ECT..........

Hope this helps you ??

2002 Jeep grand Cherokee will turn over but will not start. Have replaced battery already


There are mainly 2 reasons why a carwould not start, namely fuel and spark, remove one of the spark plugs and connect it to the sparkplug lead, hold it close to the motor and let somebody crank the starter, use an insulated pliers to hold the plug if you can hear or see a spark then you have a fuel problem, check the filtersand the fuel pump and replace if required. If you do not see a spark check the coil and replace

I don't think i'm getting spark


To confirm if your getting spark or not remove the lead coming from your coil to the center of the distributor. Place the end of this lead @ 1/4" away from a clean piece of gronded metal. Have another person crank the engine for a second or two. If you are "getting spark" you'll clearly and probably hear a small blue spark. If you see nothing I'd check in to the crank sensor.
I hope this may have helped,

1993 Mercedes 300 E 3.2 liter cranks but won't start. Smell gas


Check if you have sparks. 1- If there is no spark, check the coil for replacement. 2- If there is spark then there is a problem with the cold start valve. It is a normal close valve and only open during the cranking. When it is bad, it normal open the too much fuel coming in wetting all spark plugs before a combustion taking place. Good Luck.

INSPECTION

1. Disconnect high-tension code from spark plug.
2. Remove the spark plug.
3. Connect the spark plug to a high tension code.
4. Hold the spark plug with insulated pliers 5~10mm from a ground.
5. Crank the engine and verify that there is a strong blue spark.
If there is no spark, inspect the following points.

Step Inspection Action

1 Check for good connection of ignition coil Yes Go to next stop.
No Repair or replace
2 Check if resistance of high-tension leads are OK Yes Go to next step.
No Replace
3 Check if the ignition coil is electrically charged
1) Ignition switch "ON"
2) Check if the engine coil (+) is electrically charged
Yes Go to next step
No Check the wire harness between ignition switch ignition coil and ECM
4 Check if resistance of ignition coil is OK
Resistance
Primary : 0.36~0.44Ω (at 68°F (20°C))
Secondary : 10.9~13.3kΩ (at 68°F (20°C)) Yes Go to next step
No Replace
5 Check if ECM is OK Yes
No Replace

REMOVAL

If you have a 12 volt test light put the point on the positive lead to
the coil and the ground lead to a good ground ( Negitive side of battery ). Then turn the key on. If the test light comes on then you have power to the coil. With power to the coil confirmed have someone crank the engine and put the test light on the negitive side of the coil. The light should flash at a rapid steady rate. If not then your pickup in the distributor may be bad. If no power to coil with key on or when cranking you may have a bad ignition switch.
Another way to test for spark is to remove the coil wire from the dist cap and hold the end close to a ground ( 1/4 inch away) and
have some one crank the engine. If you get a good spark but no
spark to the spark plugs you may have a cracked dist cap or a bad rotor. If no spark at coil wire use a wire in place of the coil wire to check for spark. You may have a bad coil wire. Good luck. Neil W.

2002 Jeep Liberty Prolonged Cranking problem


it sounds like your timing system is on its way out the belt probably has streched and is close to not working at all.when u turn your ignition and applies power to the starter for the vehicle to start the piston must be in the right position when the electrical current ignites the spark plug. if u smelled gas thats from fuel that didn't explode in the chamber from a misfire, the misfire is because the spark and the chamber position are not in sync
