Check your fusebox for busted one, and replace it. And
switch the ignition on to check if you get the voltage at
your coil.

I drive a 1988 toyota conquest 2e. I recently overhauled the engin an put in a new carb,petrol pump,coil and condenser but when I drive the car just shuts off. It takes about 20minutes to start

check the voltage of the new coil
if it is a due voltage (12 volt --7.5 volts ) then when it is running and there is a resistor or lack of resistor in the run wire to the coil, the coil may be overheating and breaking down
check in your workshop manual what the correct voltage coil is for your car ( single 12 vots or duel voltage )I suspect that your new coil is a duel coil when it should be a 12 volt

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.

1986 honda civic not getting spark

Ignition coil or Igniter (ignition module), likely one is failed. First check for battery voltage on the B+ primary wire on the coil. If voltage there, may be the coil (also check distrib. cap and rotor for wear or cracks). If no voltage to the coil, might be the igniter.

1 coil pack is not working but the other two work just fine 92 cutlass supreme 3.1

Make sure you are getting voltage to the coil pack (low voltage signal from the computer. You can measure the connector with a 12v meter with the key turned on to see if you have voltage.

My 2003 honda accord v6 refuses to start. It cranks but no spark on the plug. What should i do?

Either the spark plug is faulty or the coil pack is faulty.The spark plugs get power to spark from coil packs.

If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).

But if the coil has voltage, then problem may be a bad high voltage output wire from the coil to spark plugs or hairline cracks in the coil output tower.------Getting this all possibilities checked will point towards the exact faulty part which is to be replaced.----------This should help.Thanks.Helpmech.

I have a 1967 malibu and I am not getting fire to the distributor.

try this: turn key on, momentarily jump negative coil terminal to ground to see if coil will release a spark. If no spark, use a test light to check for voltage at positive coil terminal. If there is voltage, replace the coil. If no voltage, suspect ignition switch or fuse.
If coil releases spark, check breaker points operation. If points ok, replace condenser.

If you have questions, please let me know.

No spark runns fine then loses spark wait 10 minutes starts

The spark plugs receives power to spark from coil pack.Check the power at the coil pack and also check the voltage at the coil pack with meter.If the coil pack shows proper power as well as voltage then its fault in spark plugs.Otherwise its faulty coil pack.The coil pack receives power from also check the voltage of the battery it should be exact 12 volt.
If the battery shows low voltage then the battery needs to be re-charged.
Then check out.
