Hi and welcome to FixYa,

Initially, check:
presence of spark at the sparkplug tip/electrode;
fuel entering the combustion chamber. You can check this by removing the air filter assembly and covering the mouth of the carb with the palm of your hand;
it may also just be that the combustion chamber has too much 2T oil, try replacing you sparkplug.

Good luck and Thank you for using FixYa. Happy New Year.

93 Honda Civic dx will not start. new fuel pump igniter, has spark


sorry if you guess and guess wrong. really, must be expensive.



ok got spark (and timing is good, timing light test)

if test fuel ( use instant start in a spray can) fails, with spark

then engine is bad, compression is checked, see near 80 not 150+ PSI , the timing belt has slipped. if not changed by the book

they slip and the engine grenades (or bends valves)



this is an interference engine, never ignore the belt.

there is an acid test order.

1 compression good.

2 spark good, and timed

3 fueling is last. (if spark plugs dry add fuel, by hand)



cant burn fuel with no compression and spark. well with EFI it cant run right with bent valves either.



here is Chad running an engine (any) with no gas tank

even his battery is dead. and has external battery. for 12v power.

a real trooper.

ive done this 1000s of times. in 60 years.

his engine only makes 80 psi (old) and still starts.

but EFI will never do that not that low. compression



the cam slips and goes retarded compression drops to near 1/2

and the valve timing is so bad, the exh opens late and pollutes the

next last intake charge. the card house falls and then the valve bend.



take if from me, nostarts are a blessing on any honda

maybe it saved your valves.? do the service on time./

Tip

Restoring Car's Power And Saving Fuel At The Same Time


If your car has
  1. Poor fuel responses
  2. Lost its "power"
  3. Low RPM
  4. Lower top speed
  5. Burns a lot of fuel
Then it could be because of carbon build-ups in your engine's combustion chamber. This is left behind with unburned fuel. It causes poor acceleration, a loss in power, lower top speed, and burns more fuel than it really has too. Not to mention causes smoke belching.

The best way to get rid of that would be to have a carbon ridding solution injected into the combustion chamber. The solution will liquify the carbon and other build-ups, which would then restore the "power" of your car. You'll get better acceleration, higher rpm and top speed, save fuel, etc. have a mechanic do it for you. It's alot cheaper and faster than having the engine overhauled (overhaul could trigger "loose compression").

Check engine light drive 4 blinking and transmission is slipping on my 95 accord. what should i do?


If the transmission is slipping, the FIRST thing to do is check the transmission fluid level and make sure it is full. If it is low, top ot off and see if this helps the slipping problem. Then find out why it was low (leaking) and get that repaired.

If the fluid level is not low and it is slipping, then it is probably time for a transmission overhaul.

High mileage car. Low quality Kenyan fuel. Low on


High on mileage means that the engine has done a lot of work, possible that the compression is down, need to check if this is below level, if there is oil used in excess then the engine needs an overhauling subject to the cost estimated.

Cant compromise on bad fuel as this will bring down the power of the engine.
High fule consumption means poor setting so fuel and ignition , check fuel settings- pump calibration and timing.

Hero honda splendor is my bike it has problem of oil is coming in spark plug & spark plug is short how can solve this problem


The Honda Splendor has a 4 stroke engine and can have worn valve seals or rings. If the engine smokes while riding it may be time for a top end re-build. You should complete a compression test to evaluate the condition of the piston and valves. If the compression is low ( under 120 psi ) it is time for a top end re-build.

One cyllinder is compressing at 110 and the remainder at 92


Squirt oil in your cylinders and recheck the compression. If your compression goes up you have bad rings. Check your valve tolerances to make sure that the valves are not being held open only because they are adjusted too tight. This would cause compression loss. If the valves were bent because the timing belts slipped or broke You may have to replace the valves to get compression back up. If the engine has low compression because there are 300,000 miles on the bike you may just need a complete overhaul or a new motorcycle. If you had at least 110 compression on all cylinders and they were all with in 10 pounds of each other you could still be riding on low octane fuel.

I am working on a 2005 KX250F. It had a bad spark so the CDI was replaced. Still won't start. Compression is about 65 psi cold. Valves are fair using a leak down tester. Tried using starter fluid in the...


65PSI is way to low. It probably won’t run at 88PSI either. Put a small drop of engine oil (20w50 or similar) into the cylinder and do the compression test again. If there is a big improvement in compression it means the piston rings are worn and you will have to do a top-end overhaul. As a very rough guide you need 150PSI for a 4 stroke engine and about 120PSI for a 2 stroke engine.
