The distributor has the rotor on it,and the distributor has a gear on the end of it ,witch is driven by the cam,and the timing chain turns the cam off of the crankshaft,so,therefore the timing chain has broken.

    Yes of course it would,the distributor is not turning,so it will not send any reference out.Might want to replace the water pump while you are there to keep from having to in the future.

What could cause a1991 suzuki samurai to have no fire from a new coil?


no spark from coil directly?
is the cam turning, is the dizzy rotor spinning. ????

check all fuses first. Ig-coil, FI and dome.
then using diagnostic jumper wire or fuse, (as approp)
crank engine look for code 41 o 42.!!!

USA cars , answers only
our cars are all EFI that year.
no engine swaps to Suzuki G16A/B sidekick or tracker engines.!
1: engine cranks
2: no spark
3: The ECu makes spark
the CMP sensor in the DIzzy , (never fails if rotor turns, does rotor turn, if not cam belt igored and now snapped.)
the cam turns. the CMP fires. the ECU takes this CMP signal
and fires the ignitor next to coil and the coil charges, and release and BAM spark.

that is it.
the ECU will tell you when the CMP dies or the Ignitor fails
why not ask it.
1: key on
2: diagnostic jumper in place (flashes 12s for ok)
3: crank engine,for 5sec, not 1 ,not 2.
3: release key not off.
4: see code 41, or 42, BINGO !@!!!!

Why is there no spark from spark plug 1995 k1500 silveraldo


1995 silverado has a distributor, remove the the distributor cap, make sure the distributor spins with the engine. also make sure the ignition rotor is not burned out or have a hole were it makes contact with the cap. also make sure the cap has a good carbon inside to make contact with the rotor, at this time get a screw driver, put it on the end of the wire from the coil to the cap, don't touch the metal part of the screwdriver, it will shock you if good, so put it at 5/16 from any metal on the engine, bracket, alternator , thermostat housing no matter, some one turns the engine over, check to see if the coil produces a spark, if the rotor turns, if ok it should have spark on all the wires, if it has no spark, remove the wire from the ignition coil and check if you have spak at the coil, if you have no spark, try getting a wire lead, connect it from the battery ground on one end, a screw driver on the coil to check for spark, and the other end of the wire with the key on, touch the - negative plug on the coil, that should produce a spark, if not spark yet, make sure you do have power at the coil with key on, if you do and it doesn't produce spark, replace coil. if it does spark but it is weak or yellow in color, replace coil. if coil is fine, replace distributor module,

I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

I have a Mazda astina 323 94 model it cranks but won't start doesn't seem to be any spark from the leads I have recently changed the leads , Im guessing it's the coil and distributor cap please help


1 remove the cable from the coil to the distributor.
check this agains earth, when you turn the engine over.

if spark, suspect rotor arm is not setting spark to each spark plug lead.
open distributor and clean the rotor arm with a cloth or wire wool
not sand paper as this will take off too much and cause a problem

2 check inside distributor for moisture. spray inside with WD40 or equiventy water repelent.

3 if not spark at coil open distriutor cap and with ignition on, open and close points in distributor with a screw driver and check coil again against earth again if you get sparh, problem is points not opening and closing.

4 turn over engine with distributor cover removed to see if rotor arm is moving if not then cam drive to distributor is defective. this controls points and rotor arm.

if rotor arm turning and spark at points but no spark at coil suspect Low tension wiring or coil needs replacement.

i hope this was helpful

Are you getting power to the coil on the dark green wire with the orange stripe? The relay must have power to the coil and also to the contact. If yes, then problem might be with the crankshaft position sensor.

Spark at coil no spark at plugs


Possible! Is the rotor turning when cranked over. You may have a broken scroll pin on bottom gear of distibutor.

Im not getting spark to my spark plugs


Remove the distributor cap, so that the rotor is visible. Have an assistant turn the ignition to crank the engine over. If the rotor does not turn when the engine is cranking, then you need a timing belt or chain.

If the rotor does turn, then replace the coil.

1989 Nissan Pathfinder Vg30I-V6 turn's over but wont start


Dear Phoebejanis: If your ignition coil is hot and you can get a spark coming off of the coil wire, the only thing I can suspect would be a problem with a bad rotor in the distributor. If the coil is delivering to the distributor but it travels no further, the energy must be dissipating somewhere. If a rotor has a short, the plug wires will never be delivered any spark.
Also a distributor cap with a missing carbon button which rides on the top of the rotor may be missing. I really cant think af any other things it could be.
If I have solved your problem, please let other's know by writing in, so they will learn, not to mention the ATTABOY's I might get.
Good luck.
