Question about 2010 Suzuki RMX450Z

3 Answers

My rmz 450 2010 model starts then stops after running for 6 seconds. Its not the fuel or the spark plug what could the problem be.

I have checked the fuel pump, spark plug, cleaned the carby, checked all wiring, and modules under the fuel tank. I was riding it yesterday and it died on me I got it home and it will start but after 5 seconds it stops

2010 Suzuki RMZ 450 hard to start


Hi, Brett and the usual suspects are:
1. Spark plugs in bad condition or have an improper gap or are partially fouled.
2. Spark plug cables in bad condition.
3. Battery damaged or nearly discharged, should have 12.5 volts.
4. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Throttle controls not adjusted correctly.
6. Water or dirt in the fuel system.
7. Water or dirt in the carburetor.
8. Intake air leak.
9. Fuel tank vent hose and vapor valve plugged, or fuel line closed off, restricting fuel flow.
10. Choke valve inoperative.
11. Engine lubricant to heavy (winter operation).
12. Ignition is not functioning properly (possible sensor failure).
13. Faulty ignition coil.
14. Valves sticking.

1988 jeep Cherokee Laredo won't start turns over ,has spark, gets fuel


no engine size stated, (so i toss coin, 4.0L) 5miilion strong.
the 1988 is the gawd awful French RENIX fuel injection.
i owned 2 of these pigs. (sure it runs) but sux.
why?, no CEL lamps , no flash codes, no OBD1 , no OBD ! anything.
only the very old and rare factory and dealer tools can scan this pig.
lets do this better?
in vivid details.
NO start 101: (order matters too)
  1. compression at spec, on all 6 cylinders? (old engines do die)
  2. spark at all 6 spark plugs good,? not just 1.
  3. car is tuned up. spark plugs.cap rotor, wires, and filters?
  4. the ign timing light on #1 wire, shows spark landing near TDC 0 degrees or under hood stated spec. (open hood look up )
  5. i now check for flooding, is it? spark tips , TALK to me.?
  6. yes, then check fuel pressure. next.
  7. no, then are they dry, you said wet. ('gets fuel means what"?)
  8. if flooding, i unplug the fuel pump relay and start car with test fuel if it runs for 3 seconds and stops, that is a PASS condition so but if not 1, to 7 above was skipped. lets say its flooding
  9. if flooding did you try cranking per opr guide wide open throttle? this CUTS all fuel and clears all flooding on all gas engines. and for sure all EFI. gas engines.
  10. my guess is its running now. right? if here?
  11. if not, check fuel pressure per the fsm cranking, and the MAP sensor. out put voltage key on, and cranking. and post that.
  12. good luck.

get the engine to run on test fuel first. this saves big time labor
down time, and wasted parts , guessed at)

doing a real tuneup , is not ever a waste.
a tuned up engine pays back in lower gas costs. big time.
fuel is expensive.

My 2010 rmz 450 crackles and pops at low revs, and surging when cruising, also backfires when i shut of the throttle, i have fitted a wiseco fuel mangement unit and played around with it but no luck,


sounds like a few things, bad/fouled spark plug,old/clogged fuel filter/old air filter or bad fuel. When taking bikes out of storage bikes often suffer from this problem from old fuel sitting in bike gumming it up.

Hi I have a rmz 450 on a 06 and the valves needed doing so I put new valves in reseated them set up timing all ok went out on the bike no prob started good as always didn't ride again for a few weeks got...


If the timing is right and you have spark, then it could only be a fuel issue. Does it have enough fuel getting to it? Have you checked the needle and seat in the carbs for wear or debris. Try undoing the fuel bowl drain plug and let some fuel out, if nothing comes out, try turning your fuel on. If on, and it is a vacuum tap. Check that you are getting good vacuum for the fuel to come out. If it is a gravity feed, take the hose off the carb and turn tap on to see if enough fuel is running out.

Doesn't start has spark @ plug fuel @


try starting meaning pull the rope 6 times and then check the spark plug if its wet clean it or try a new plug, if its dry your not getting fuel in the cylinder which means carb problems. if you have a seringe or something to put some gas into the spark plug hole then install spark plug and try it. if it runs for a couple of seconds then you need to focus on the carb. only put a small amount of fuel in the plug hole if you try it otherwise youll be pulling on the rope for awhile before it will start. hope this helps.

My 1997 S-10 v-6, 4.3 vortec just stopped running and will not fire at all. It has gas in it but will not fire. It only has 90,000 miles on it.


Turn the key to run and listen for fuel pump in the gas tank to run you should hear a buzzing noise that should only last 3 to 5 seconds then will shut off until you try to start. You should also hear the fuel pump relay click off under the hood. If fuel pump is good you need to check for spark at one of the plugs.

Put in a new spark plug and check plug wire connections and ECM ground connections.

You probably have weak spark and when bump started the plug sparks strong enough to run the engine.

A weak battey can also cause this. Your ECM needs a minimum of 9V to work. (the ECM gives spark and timing) When kicking over, there is not enough volts to spark. When bumping over the alternator provides the extra volts to start the bike.

Hope this helps!

Stihl weed eater runs 2min. then stop


Stihl weedeater was running and stopped suddenly. Put in a new fuel filter and cleaner air filter with soap and water. Checked spark plug and it appeared fine. Started the weedeater, ran for a second or so and stopped. Spark plug wasn't gas fouled. Could it be the carburetor needing new diaphram gasket and spring.
