Cranks but no spark

Start with testing the coil. Disconnect the wire and have someone crank the engine to check for spark. The spark should jump about 1/4 inch. If spark is good, suspect fuel problem. Spray some ether into the intake while the engine is cranked. If it starts and then stops, it is a fuel problem. Your battery is probably going to go dead with all this cranking, so keep a charger on it. Also give your starter time to cool between long cranking.

Check some fuses or see if you are getting any kind of spark. Spark at the plugs or injectors.

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 !@!!!!

which engine?

cranks but will not start or remain running

tune up time, cold damp cause spark parts bad

oldest story in world. damp conducts, bad insulators do wet.

end result , bad spark.

flooding ? crank wide open throttle, (oper, guide, on start page.s...)_



check spark..,got spark to all cylinders

yes,

try test fuel, if not flooded,

starts then stalls?

Does this engine have fuel? Does it have spark? Is it getting air? These are the questions you need to answer. First thing you should check for is spark due to it being the easiest to diagnose. Hope this helps. Btw air is almost never the issue. So check for fuel next

Cranking is Turning Over,same thing

Remove a spark plug and connect its wire back on it and lay the plug against the engine...crank engine to see if you have spark.

If you have spark...put plug back in and move to fuel system.

Wait a minute...if your engine is not cranking or turning over...then check your battery and starter.

Try spraying starting fluid into the air intake, with the help of someone else starting the car. As they crank over the car, spray the starting fluid into the air intake. Do this for at least 15 seconds. If the car tries to start up the fuel pump has probably gone bad. When turning the key to the on position do you hear the fuel pump humming? If the pump is not humming the fuel pump is probably bad.

could very well be a faulty sensor, leaky vaccum hose, bad coil packs, needing of new fuel filter, spark plugs, wires.

Have you checked your fuel pressure to make sure it is good. You can do this with fuel pressure tester on the fuel rail.

Also check every cylinder for spark
If you don't have any spark, or very weak spark, you could have bad coil pack, module, or crank sensor.

You can remove one plug at a time, and place it back on plug wire, place it on top of engine block, have someone else turn motor over well you observe to see if there is spark.

Do you have a service or check engine light on? If so, I would have the engine codes read to pinpoint exact problem area.

Let me know if you have any questions or need further help

Hello, I'll need some more info, when u turn the key to start the van, the engine turns over (this is the same thing as cranks over, or cranks) but it won't start. Do I understand it correctly? If this is the case, u must check to see if u have spark at the spark plugs, if u do u must then check to see if gas is reaching the plugs. Those are the 2 main requirements of an engine running, spark and gas. The easiest way to check for spark, is to purchase one spark plug for your van, remove one spark plug wire by pushing in, while twisting, then pull out while twisting the wire ( hold the wire as close to the spark plug as possible so u won't damage the wire). Connect the new plug to the spark plug wire, place it on a metal surface, turn the key to crank the engine over (do NOT hold the plug while turning key on!!) , watch the tip of the plug for spark. Do this out of the sun, and it will be very obvious if u have spark at the plug or not. Let me know what u find.
