Question about 1985 Nissan Pickup

2 Answers

The fireing problem with my old truck could very well be that the high tension distributor coil is going out. What's the best way to check the coil?

This has been an ongoing problem. The engine cranks but is hard starting when cold, and won't fire at all when warmed up. Starting fluid doesn't help.

If your old truck ( you didn't mention the age ) has a points system distributor then replace the condenser and check the point gap. Quickest way to check a coil is to replace it with a known good coil . If at any time you have left the ignition on with the engine stopped then the constant current flow will burn coils

Distributor not firing

We need to know what you mean by "proper power". There is a wire from the distributor to the coil which carries 12 volts and another from the coil to the distributor that carries upwards of 16 000 volts. The first is a thin one which allows the points to fire the coil, the other is the thicker high tension wire that comes from the coil to be distributed to the plugs.
If you have fire on the high tension wire but no fire on any of the plug wires, you have either a bad rotor or a cracked distributor cap or even the little carbon thingamajig inside the distributor cap might be broken or missing.
If your truck has a points ignition, you might have a bad condenser (capacitor) or the points are not set to the right specification (about 16 to 18 thou)
Check that the points are not burnt, which will also indicate a bad condenser.
You might reason that there is noting wrong with the points or condenser, but you can still get a nice spark which looks good, but is not sufficient to do the job.
The distributor cap might have a crack that you can't see with the eye, but a small crack will give you endless headaches.
Replacing the whole distributor is a very very very last fix.

My toyota 5e engine backfires

Engine back fires due to:
- Wrong heat range of the spark plugs.
- Spark plugs gaps too wide.
- High tension cords defective.
- Rotor, distributor cap or distributor assembly defective. (Only on distributor type ignition system).
- Ignition coils.
- Fuel pump pressure too high. (regulating valve stuck closed).

I got fire to my points on my 4 cylinder 1932 ford but not to my plugs what's wronghat wrong

Could be a bad coil. Check its resistance and compare to specs (find some real old mechanic to tell you what specs to expect, if you have to-lol). Also could be a bad high tension lead from coil to dist. cap-can also be checked for too much resistance.
Do the points open and close when engine is cranked? Are they set right-about 0.015 inches- or two matchbook covers placed together? If coil and high tension cable are good, and points are good and set right, the condensor that goes with the points may be bad-try a known good one-I'm assuming that old car has a condensor to trap the current when points open so no sparks at points occurs.
If everything checks out so far, maybe the distributor rotor is not making good contact to transfer the high voltage current from the coil cable to the spark plug wires.

I have a 1942 Dodge truck that has no spark to the plugs. The coil has a wire coing to the distributer and on the back of the coil there is a cable going to the ingnation switch. Is it the coil?

It could be, but anybody with a multimeter could quickly test it, give you a good idea if it is good or not. Just take the two wires off-the wire going to the distributor would be the negative side, and the wire from ignition switch is the positive side. There should be a + sign, and a - sign on each side of the coil case where the wires connect. Then remove the coil to distributor high tension cable, remove the coil from it's bracket and take it to a friend or shop to have tested. All they would do is measure the resistance of the coil at two places, using an ohmmeter (part of a multimeter), to see if it is within specs. A shop charge should be like $5, if they would even bother to charge you.
What else might it be? Well, one could check if power is passing from the switch to the coil on that wire. The wire on the coil should show battery voltage, or very close, when key is turned to on. Also examine your plug wires for brittleness or cracking. If no spark at any plug, it could be a bad coil to distributor high tension lead-the one from coil tower to center of distributor cap.
Also pertinent to note that the mechanical points and condensor assembly inside the distributor has to be working right for spark to occur. This is what the small wire from coil to distributor connects to- the points. Someone knowledgeable about how it works would need to look at it-the points have two small electrical plates or contacts that open and close as the distributor shaft turns around. This opening and closing is what makes the coil able to generate the high voltage for spark to occur at the plugs. Higher voltage travels from the coil tower to the top of distributor, and on to the individual spark plug wires, routed to each in turn in the firing order by a simple device called a rotor.
Take off the distributor cap, and right on the top of the distributor shaft is the rotor. It has to be in good working order to transfer current from the coil high tension wire to the individual spark plug wires.
Post back. Keep me informed of your progress. You must have the old 6 volt system? Amazing! Buy new plugs, plug wires, points and condensor for it. And a coil, if you need to-good luck. Parts may be hard to find. First check locally, may need to go online for a vintage parts supplier.

2003 sonoma; occasionally RPM goes irratic then truck will stall out even when sitting idling. changed out fuel pump,fuel filter.distributor and computer

Generally eratic tacho fluctuations as a result of the high tension side of the coil firing into the low tension side. This can be inside the coil or through a carbon track formed outside the coil. If your model has the coil in the distributor cap you will need to replace both the coil and the distributor cap to be sure you have sorted the problem, be sure to use plastic screws to hold the coil inm not metal ones, metal screws will lead to carbon tracking very quickly after fitting the new unit. Once a carbon track has formed it is almost impossible to remove it entirely, the problem will keep returning.
hope this help

Remove distributor cup mark position of the distributor rotor start for a second and see if the rotor change position if is not is your timing belt is broken ,if change position check high tension lead from the coil ,rotor,and high tension leads ,coil positive lead and negative. check fuse .

92 civic engine stalled while driving; fuel pump works; replaced all plugs seeing some oil on old ones. only one plug fires; is coil still working? or the distributor? haven't checked fuel...

Check the ignition distributor cap and clean the electric contact points it might be already dirty.

if one has a spark that means your ignition coil is still okay. Remove the whole cap and check the inside part and clean it, use emery board.
Check also the high tension wires( spark plug wires ).
Hope Fixya helps you!

You have problem with you timing or did you ever label all the high tension wire before you unplug it. it might be re arrange the firing sequence. 1342 firing order. And the timing position of the distributor were at original place.

have your already check the high tension wire and the distributor cap maybe the contacts have corrosion in it. Try cleaning it with a sand paper of the contact point on the distributor if you have.
