    Where is the relay and fuse you are talking about ? I checked visiably all the fuses on the pass side (under the hood) fuse block and those looked ok. Whats next ?

  • craighook Dec 10, 2008

    I believe it is the smaller of the engines... spark coil is square, appears good. When I connected 12v to the coil and cranked the engine it still would not start, however did not check for spark (darn)
    Coil has continuity on 12v side anyway.

  • craighook Dec 10, 2008

    power from ign switch had everything else on when in the "run" position. I disconnected the coil at the coil connector / harness. no 12 volts when switch on, tested with meter at the harness female connector.

  • craighook Dec 10, 2008

    no, I do not have 12 volts from the wiring harness to the coil

  • craighook Dec 10, 2008

    Alternator is ok. Was driving on the road about 45 mph when engine cut off suddenly.

  • craighook Dec 10, 2008

    there were 2 wires going to the coil from the wireing harness... one was black, the other I will have to check. I assume the black is common and the other is +12VDC. So, if I supply 12v to the coil via cheater wires, the coil should spark when cranked ?

  • craighook Dec 10, 2008

    There is a computer in this car that was replace a few years back.... does the power come from there ?

  • craighook Dec 11, 2008

    this is the small 4 seat sedan. is the Hall effect sensor wires at the bottom of the distributor housing ?.. there are some wires going in there.

  • craighook Dec 11, 2008

    Car battery is fine, cranks engine normally.

  • craighook Dec 11, 2008

    the only wires I saw coming out of the square coil were 2, on a connector and of course the spark wire to the distributor.

  • craighook Dec 11, 2008

    How can I test the Hall effect sensor in the Distributor ? 12/11/08 10:38 E

  • craighook Dec 11, 2008

    Battery is good

    This is a Colt, NOT a Vista Wagon

I think you aught to be looking at the starter motor itself, the car cranks fine but doesn't fire up by the sounds of it, also check the spark plugs themselvesas, one or more of them may have become degraded or just caked in oil.
If its a diesel car check the glow plugs for continuity (these are just like spark plugs but are connected together with a heavy duty cable)

Regards

    this is what the starter motor looks like sometimes tapping on these with a hammer gets them going again but eventually needs repalcing.

    This is what Glow plugs look like (if your car is diesel)

    The wire that connects to all the plugs may be degraded or a plug itself may have burnt out

    regards

There is a ground wire tuched to the car body,, check that wire is in place,

note -
1. without that wire there is no importance of your battery power (12 volt).
2. wire colore is green.

Thanks

What about alternator. It might be dead.
Distributor cap. It might be worn,damaged
What about jump starting. Does it help.
Also what about timing belt.
Good Luck

Your power supply goes straight from ignition switch check this also if you have the 1.6 engine possible cause would be the power transistor

    possibly the hall effect switch in distributor. you would have 12volts on one side.Is this car a colt or colt vista?or wagon??

  • TripleTauto
    TripleTauto Dec 11, 2008

    yes it is in the distributor. they can give some problems.looking at the diagram coil gets its 12volt from power transistor

  • TripleTauto
    TripleTauto Dec 11, 2008


    1. Connect the positive lead of an ohmmeter to terminal # 2, and the negative lead of the ohmmeter to terminal # 3. Continuity should NOT exist.
    2. Connect the positive lead of a 1.5 volt battery to terminal # 1 and the negative lead of the battery to terminal # 2. Continuity should exist, while the battery is connected.

    3. be sure to disconnect connector to transistor when doing this test.

  • TripleTauto
    TripleTauto Dec 11, 2008

    this is how to check power transistor

  • TripleTauto
    TripleTauto Dec 11, 2008

    this is not on the coil it is the power transistor should be on intake

  • TripleTauto
    TripleTauto Dec 11, 2008

    STARTER?GL;OW PLUGS? WTF?????

    I have given you info on a colt.the info i have given is for the 1.5 as you say you have smaller engine. The power transistor is located close to coil check this

12 volts is supplied by the ignition switch, test the switch and make sure it is working correctly, pay attention to the wire colors and whether or not u have a resistive wire to the coil from the ignition switch..

    There is no realy or fuse, that is incorrect.

    what is the voltage at the + side of the coil connector, coil connector disconnected, u must disconnect, if the coil is defective u can show no volts.

  • yadayada
    yadayada Dec 10, 2008

    What do u mean coil has continuity on 12 volt side, it does have 12 volts from the ignition?

  • yadayada
    yadayada Dec 10, 2008

    U have to trace that 12 volt lead back to the ignition switch, that is where the problem is, the wire to the coil may be the same color as it is at the coil, I did this kind of work 20 years and that is how I would approach the problem, Japanese ignition switch's are famous for just this kind of problem, only 2 companies make switch's for Japanese cars so they pretty much share the same problems.

    does the check engine light work?

  • yadayada
    yadayada Dec 10, 2008

    The black wire is not the common, it is the secondary of the coil, it is what is switched to cause the coil to produce a spark.

  • yadayada
    yadayada Dec 11, 2008

    Why do u want to test the hall effect sensor? if no power to the coil is the problem, u are really confusing us here, do the coil have power??

1990 964 wont spark


run the fault codes first as there are a number of reasons for no spark --the last being the coil. There is an ignition module ---position sensors --timing belt --shorts in the cap --bad coil lead to the distributor . The ignition module may be only have 7.5 volts to it from the coil in which case you may have burnt it out with the 12 volt application and you will not get any spark unless the coil is in the circuit as it is a transformer that generates the high voltage necessary for a spark at the plugs.

I have a 1990 f-150 with a 300 straight 6 cylinder. I am getting voltage from battery to coil but no spark coming from it. I have replaced it and distributor also and still no spark. anyone got any ideas?


Replace the coil and ensure that you get the correct coil voltage for the vehicle Coils come in to voltages Straight 12 volt coils that start and run on 12 volts and other that start on 12 volt and run on 7 volts. Check if it needs a resister with it.

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.

1991 Cutlass ceirra 3300 ,runs fine for short time. starts running rough,then dies/will not start again.changed fuel filter, then tested fuel pump.fuel pressure is good.what next ?


Check for spark when it won't start. If you have spark, might be your fuel pump relay, maybe the map sensor. If no spark, check another or all plug wires. If ignition isn't working, it could be Crankshaft Position sensor, Camshaft position sensor (or pick-up coil), ignition control module, coils, pcm, or the wiring associated with them. PCM determines spark timing after inputs from crank and can sensors, and sends ground signal to ignition module, cutting primary voltage to coils, initiating spark or high voltage from coil to sparkplug. All these parts have to be working right for ignition. All can be tested too. You'd need a digital volt ohm meter (DVOM) and a repair manual for your car with the test procedures. That Mitchell alldata-diy site has a special on subscriptions, pretty reasonable for a 1 month subscription, and excellent info and troubleshooting flow charts, wiring diagrams, etc.

A test light connected across the coil primary leads should flash on + off when engine cranks(coil sparks when 12v turned OFF due to collapse of magnetic field).If you get pulsed 12 volts,and no spark from the coil,the coil is bad.If you don't get the pulsed 12 volts,trace back to find out why(the PCM turns the coil ground on and off,12 volts comes from switched IGN source)

1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?


First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.

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

Start with the control module,I think it is located under coil on this model,You have checked the rotor to see if it is turning haven`t you?If it is not you may need a timing chain.
