To do accurate testing you will need to get a chiltons or haynes manual and follow the procedures listed. The system is not terribly complex but guessing will cost you money. Before testing, check coil wire and harness connections to make sure they are OK. If you need advice concerning any part you tested just ask.

When were your spark plug wires last changed? And have you checked your ignition module? Crank shaft position sensor is another item to have checked.

1990 geo storm sohc is running rough. Parts that are new: cap, rotor, plugs wires,plugs, pickup coil, and the ignition module looks brand new. The coil is old, but is still sending spark through all t


the timing is 180 degrees out so ignore where no 1 lead should be and rewire the HT leads to the new position for no1 cylinder. The crank timing mark should be on 10 degrees advanced. Engines are timed off the crank position so forget the cam position.
Or you can start again. Remove no 1 plug and turn the engine over until you feel compression under your finger over the plug hole. Set the timing on the crank to 10 degrees before tdc. Position the distributor so that the point of the star is directly opposite the exciter coil in the distributor. The rotor button should now be facing no 1 cylinder plug lead adjust the HT leads so that they will fire in the 1342 firing order. Start the engine and with a timing light attached to no 1 plug lead adjust the timing mark to specifications by turning the body of the distributor.

87 Toyota p/u 4x4 turns over won't start no spark at coil coil has 12 volts on both wires why is this should I have 12 volts on wires going to pickup in the distributor if so which wires should be hot???


12 volts at the low tension wire , hundreds at HT (high tension ) leads , they go to each plug, dont try testing them with a volt meter you will blow it up , and your hand as well,take one plug out , put the ht lead on it rest plug against the engine block , get someone to crank engine and watch plug to make sure you have a good spark, if not change the ign coil/s

Truns over but want crank


An engine spinning just means your battery is good and starter works. You'll need to find out if you're getting the other things you need. Those being air, fuel, and spark.
For air, take the air filter out of the picture by removing the air flow going to the carb. Try to start the car.
if it doesn't start, for Fuel, try spraying into the carb some starting fluid then try starting the car. Does it run for a little bit with the starting fluid you just sprayed in there? If so, you've probably got a fuel problem.
If the engine still won't start, take one spark plug out and keep the spark plug wire attached to it. Make sure the spark plug is touching metal so it's grouned electrically, like laying against the engine block. Don't hold the spark plug because you can get a good shock if you hold it wrong. Just lay it on the engine block. Ttry starting the engine and watch for spark at the end of the spark plug. Sometimes the spark is hard to see so doing this at night or in a garage will make it easier to see the spark which leads me to another point. Sometimes your sparkplug wires get so old they electrically aren't any good anymore. You'll be able to know that if you start your car at night and you look under the hood and see little sparks jumping from your spark plug wires to ground. This means your spark plug wires need replacing and that could be your problem. Usually the engine will run when this happens but it won't run very good as most of the spark is being shorted out.
So try to isolate where the problem is...Air, Fuel, or Spark and go from there.

Car wont start but kicks over


Since you do have A fully charged battery and also you do receive fuel smell after crank start and the car wont start,either you do have an Ignition fault means not giving the spark,advice remove the spark plugs and check whether are wet with fuel,see whether are black,if so change them and before start check by leaving an HT lead off a spark and use one of the old ones connected to the HT lead and earthed to the engine,ask somebody to start the engine checking for any spark comes out. If yes then put the HT lead back to the new spark on the engine and try. If ther is not any spark,then you have to go backwards from the HT leads to distributor,Rotor Arm,Electronic igniter,Coil if is fitted,Fuse and relay. Good Luck.

Turns over but won't fire


If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.

2001 ford taurus with the 3.0 after sitting a few hours when i go to start will crank and crank and crank for what seems like ever, will start easily after that but when i go to start it for the first time...


Its not the oil, increasing temperature will thin out the oil. If it cranks easily but won't start it could be the spark plugs or the spark plug wires. When they heat up, especially if they are old, they won't perform well. Pull off one of the wires and hold it close to the plug, try to crank the engine and look for a spark. If it sparks them try removing a plug and check to see if it looks wet. If its bone dry it might not be getting fuel.

My 2000 Dodge Grand Caravan will crank but won't start.


Hi, if an engine cranks but refuses to start, it lacks ignition, fuel or compression. When the engine cranks normally but won't start, you need to check ignition, fuel and compression. Ignition is easy enough to check with a spark tester or by positioning a plug wire near a good ground. No spark? The most likely causes would be a failed ignition module, distributor pickup or crankshaft position (CKP) sensor.
