THE POINTS COULD BE STUCK OR YOU HAVE A SHORT TO THE COIL OR DISTRIBETER.

SOURCE: 1981 Fiat 124 Spider. No spark coming from coil.

Assuming that you have a fully charged battery then you should check/replace the ignition points and condenser. This should ideally have been checked before investing in a new coil.

If in any doubt then just replace them as it's cheap and easy. Note that most Fiat 124 Spiders are a little more complicated than normal cars as they're often fitted with two sets of points instead of the usual single set. One set is used purely for starting and the engine switches over to the other set once it's running at full oil pressure.

Assuming you have a 1600cc dual point 124 Spider then look at the following web address to see how to replace and adjust your points:-
http://www.mirafiori.com/~thad/points.html

Note that although the points can be set roughly using a feeler gauge it's vital to adjust them correctly using a dwell meter.

The next web address gives you the specs for the US specification Fiat 124 Spider which usually had a single points distributor (points specs on page 21):-
http://homepage.mac.com/tmckaskle/fiat/images/specs/index.html#page1

When doing this job also check and replace both the distributor cap and rotor arm if they show signs of damage, burning or excessive wear.

This is not a difficult job, but it is fiddly. I usually found it easiest to remove the distributor from the engine to work on it but that does mean that you need to mark the position of the rotor arm as the distributor is withdrawn to ensure that you don't completely lose the ignition timing when you've finished. You'll need to recheck and adjust the timing afterwards whether the distributor is removed or not anyway.

No spark from coil to distrubuter


Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

No spark when starting


COIL ON DISTRIBUTOR MAY BE SHORTED...

USE A 12 VOLT TESTER TO CHECK...PLACE RED WIRE FROM TESTER TO BATTERY...PLACE BLACK LEAD TO BLACK WIRE OF DISTRIBUTOR, CRANK ENGINE, IT SHOULD READ POSITIVE 12 VOLTS...IF NOT IT IS SHORTED... however this is not set in stone. DON'T USE A NINE VOLT TESTER...

USE A OHMMETER, CHECK THE RESISTANCE BETWEEN THE SIDE TERMINALS OF THE COIL, DISCONNECTED. YOU SHOULD SEE 0.75 TO 0.81 RESISTANCE. THEN CHECK THE RESISTANCE BETWEEN EITHER SIDE TERMINAL AND THE CENTER HIGH TENSION TERMINAL. THE READING SHOULD BE 10,000 TO 11,000 OHMS. ANY SIGNIFICANT DEVIATION FROM THESE NUMBERS WOULD INDICATE THE COIL COULD BE DEFECTIVE.

1990 Dodge Ramcharger won't start. Battery output 12v, voltage across coil terminals 6v, voltage output at coil port to coil wire 6v, voltage of coil wire output to distributor 6v. Engine will c


There should be a small white ceramic block on the firewall - this component cuts the battery voltage from 12 to 9 volts for the coil and ignition system. It has 4 wires and is called a ballast resistor.
You may need a book with the wiring diagram to be able to test it. You should have battery voltage going in and something like 9 volts coming out.
You can also run a wire with a fuse from the battery to the positive side of the coil to check the system. Disconnect the factory wire from the coil first.

Have a look at the coil and its supply lead, standard it has a 9v coil and a resistor wire in the harness, this gives trouble ar resistor wire is odd and will not solder or weld and its expansion when hot loosens crimps! If you put 12 volts into a 9v coil it overwhelms (magneticly) the windings and gives a poor spark, also burns the points.

Just finished 12 volt conversion on 49 V8 flathead. Starter engages but engine won't start. Appears to be getting fuel.


You might not have spark as the 12 volts needs a ballast resistor or the points burn out preytty quick. 8 volts at the coil in run with the points open and 0 with the points clsed and battery voltage at the coil when cranking. coil wire near the intake manifold while cranking should jump at least 2 inches. Closed points should be 0 volts at the neg on the coil. pos and neg should be the same 12 volts with the points open. if not either the coil or the points are bad. The condenser can fail and no spark with all the rest right

No spark between the distributor and coil


You need a voltmeter or test light to find 12 volts on one side terminal of the coil--the other side terminal goes to the distributor. If both sides have 12 volts, then the points may be dirty. If no 12 volts on the coil, trace that wire back to a resistor block on the firewall--check both ends for 12 volts. If still no 12 volts, check the ignition switch. Have you checked for a blown fuse?
Generators are usually nearly totally enclosed and long with several terminals sticking out. Alternators are shorter and wider with lots of ventilation slots and several terminals on the back. They also have a prominent fan behind a smaller pulley. You might see if you can find a Haynes service manual for this car if you are on your own.

I have a 1991 chevy truck, I am getting no spark. I have changed the ECM, distributor and coil. still no results. I have no idea of what to do.


check to see if your truck has a crankshaft position sensor, its usually located behind the harmonic balancer or right near there, if the sensor went bad or if the wiring got messed up there will be no signal to the ecm telling the ecm when to send spark to the coil. the crankshaft position sensor is responsible for telling the computer when to fire the spark plugs based on rpm and timing. check the wires on the crankshaft position sensor, if they look fine, replace the sensor, hope this helps!
