My scooter was parked for a year. I changed the coil and spark plug. Now it turns over and will run for about ten sec. Then sputters out. Any help?

Did you empty out all the old oils and replace them? Also it would need fresh gas and it may need a new fuel filter. I had a car that would start and quit bc it needed a new fuel filter.

SOURCE: When bike gets worm it runs like ****

Since you have thrown the entire ignition system at it, let's think about fuel. If you were running out of gas it would act as you described. I would start by removing the float bowl. Be careful not to spill any gas because we want to look at the level. It should be over half full. Check the float movement. You should be able to push it up without resistance. Looking from the bottom remove the phillips screw that retains the float axle and the float and needle valve should fall out. If the needle valve has three sides or if the rubber tip is worn, replace it. The 3 sided valves have a tendancy to stick closed and all dealer stock should be the 4 sided version by now. After you re-install the float, leave the bowl off and follow the small vacuum hose from the petcock to the carb. Pull it off at the carb end. Look to make sure it isn't damaged. **** lightly (sorry) or use a vacuum pump on the hose. With the petcock on and gas in the tank, a healthy stream of fuel should pour from the needle valve. If not, the petcock diapragm is shot. If none of this helps, take it for a ride and when it acts up, crack the fuel cap loose and if it takes off the vent in the cap is malfunctioning.

SOURCE: still no spark to plugs even after replacing coils.

Either your pulse generator does not give right pulses to the ECU or your ECU need replacement.Find the wires that travel from the pulse gen to the ECU to check them for pulse.

Sounds simple, but do you have a kill switch on your scooter? Be sure it is not in the kill position.

Pull that new carb off and see if the jets are even screwed in, and the float is together.

i bought one and same thing, when i took the bowl off, all the jets were just laying in there and the float pin wasn't in. i put it together like it should be and works great.

i thought they came already asembled, because they look assembled, but the internals were not.

If thats not the case, your float is stuck, sometimes you can tap the carb and the vibration from the tap will free it up.

Hi, Anonymous and the usual suspects are:
1. Spark plugs in bad condition or partially fouled.
2. Spark plug cables in bad condition and leaking.
3. Spark plug gap too close or too wide.
4. Faulty ignition coil, module, and or sensor.
5. Battery nearly discharged.
6. 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.
7. Intake air leak.
8. Water, dirt, or rust in the fuel system, carburetor and/or filter.
9. Fuel tank vent system plugged or carburetor vent line closed off.
10. Carburetor controls misadjusted.
11. Damaged carburetor.
12. Loose, dirty, or corroded ignition module connector at crankcase.
13. Faulty MAP, CKP, O2, and/or CMP sensors.

98 expedition 5.4 4x4 with dual a/c..sputters and shakes while idle and driving...please help me ! i have replaced 5 of the 8 spark plugs till i can get to the back 3 (pain in the ****) no change not even...


When you know the symptom who needs codes?And if there was a code it probable say lean bank 02. why simple you have a misfire. the smell rich exhaust the shake and sputter in drive. 2 causes the Expedition suffer from ,An open EGR valve.If you can change a fuel filter and change a spark plug you can test this. when the engine is running and misfire at idle and the vehicle is warmed up and at operating temperature. Turn off engine. Go to the EGR is it hot to touch. because if it is it open and this the the culprit.Another misfrie is from COP (coil on plug.)When you change the spark plug where any of the spark boot torn or worn that spark can go through. Or even a faulty COP will do this .To find it you have the engine running and lift one COP out of the cylinder and listen for a engine drop if the engine RPM drop the COP is good if no change in engine the COP is bad. By the way 600rpm in drive is low

Hi, Specialmo539 and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, 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.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

Ignition bike wont start


check the battery coil wire

Engine turns over, won't start, no fire at plugs. There's plenty of fuel, and no fire from any of the plugs. All fuses and fusible links are good. I pulled the plugs to check for a spark, and there's no...


What are you wondering is correct. Let check the coil first. if coil is good the there is a problem with the ignition module. If the ignition module is good then a problem with the crankshaft sensor. The coil can be checked by measure resistance of the terminals of the primary coil and secondary coil separately to see if it open. To check if it can generate a spark, once you identify the primary coil terminal, run 12 V wire to these terminal, connect a spark plug to the secondary coil, by just leaving a spark plug with connected with spark plug wire and let it touch the engine chassis. Now you have to make pulses at the 12 volts connection by making a break and connection several time to turn it on and off to generate the spark at spark plug. The ignition module is supposed to do what you are doing now to generate the spark. If it is bad, it can't do what you did then a spark is not generated. For the crankshaft sensor, only the shop can tell you it is bad or not. Good luck.
