318 engine with no spark to coil or spark plugs. how do i fix this


William, your car uses a ballast resistor that causes what you describe. This is usually a ceramic white, rectangular piece, mounted on the firewall.
The voltage to the coil has to be dropped to 8 volts, or so. Chrysler handles that with a ballast resistor and it fails.
To test, you can wire across the resistor and see if you have spark.
My recollection is one side is for the coil and one side for the wipers or something like that.

This is a common problem.

Have a 67 tang with Mallory coil and distributor


check firing order and ignition timing. Ensure that you have connected the distributor up correctly to the coil. Check to see if the unit requires tacho (rpm gauge) wires connected. Some of these units need the rpm's reading as the ignition pulse determines the advance of the spark

Why would 1995 toyota hiace with 2rz motor with carby shuts down when hot.


what you should have in the electronic distributor is an ignition module with a coil outside wired to the distributor. The ignition module creates the pulses needed for the coil to generate extreme high voltage . If that coil is incorrect voltage for the system then it is most probably overheating and failing to work. There are to voltage coils that can be used . One is a straight 12 volt coil that starts and runs on 12 volts and the other is a start on 12 and runs on 7.5 volts with the run circuit going through a resistor or resistor wire . Check out which coil should be in your car and if correct (7.5) check the voltage to the coil with a multimeter and it be should read 7.5 volts when the ignition is in the run position

I have a 350 chevy engine using a mallory unilite distributor what is the spark plug gap for champion platinum plugs number 3025 the engine is 1978


Without any more information than this I have to say it should be between 32 and 35 thousands. I don't have the info from the ignition system that your using, Have you checked the manufactures suggestions. Unless this is a super spark ignition then the gap I quoted should work.

I have a 1992 toyota pickup ext cab, 4x4 V6 420 000 km. I have swapped the engine out for a 1994 toyota 4runner V6 220 000km, same identical engine. i replaced the timing, intake seals, oil pan seal,...


Try a hot wire to the distributor. If the engine keeps running then the problem may lie with the ignition circuit wiring. It also might be the ceramic resistor.

No Spark from coil


i don't beleve 3 volt is enaf for the coil it has to be at least 9 volts
if this car has a resistor on the car or on the circuit going from ignition switch to ignition coil replace it, but if it does not have one then it has to have one built in the circuit wish is going to be very hard to find i will recomed you to get straight ignition power from ignition sw, to an aftermarket ignition resistor and from there to the positive side of ignition coil,
but also let me know what promaster means? is that the brand? or is that a performance coil?
and does your car has elecgtronic? or points system ignition distribuitor.
