My engine turns over but doesnt fire up


Check and make sure you have fuel pressure at the fuel rail, Then make sure you have spark at the plugs. If you have both spark at the plugs and fuel pressure at the fuel rail I would look at the pick-up in the distributor.

2003 Buell Blast starting problem


It may depend on what you call choking the engine off. If you actually choked it off you may well have flooded the cylinder and plug with gas and now have wet plugs. Often in high performance motorcycles like your Buell even with a new plug that has never been fired or only fired few times it it gets wet it may still look brand new but refuse to start the engine because it got wet. SO, try new plugs and do not choke it off when you want to stop it.

Why my 1996 cadillac fleetwood brougham not getting any fire to the engine?


Your question needs some additional details. Are you sure that it is not getting fire to the cylinders or are you just using the term "not getting fire" because you are not getting any response from the engine when trying to start the car? Does the engine turn over? I would assume that it probably does based on your question. If your engine turns over then the first diagnostic step to see if you are getting "fire" (spark) to the cylinders is:
- Remove a spark plug wire and remove the corresponding spark plug.
- Put the spark plug wire back on the spark plug.
- Now hold the spark plug thread against a metal part of the engine
- You may want to use rubber gripped pliers to hold the spark plug
- Have someone turn over the engine.
- Watch the end of the plug to see if you are getting a spark jumping the gap to the ground electrode (little metal arm suspended in the air at the end of the spark plug).
- If you are getting spark then you are getting fire and your issue is most likely fuel related or timing (spark synchronization to the cylinder cycle).
- If you are not getting spark, then you have electronic/electrical issues

Let me know what you find out...

Bought unit new last summer. Used it once last summer and once this year. It started fine both times. Today, it will not crank. I have replaced the spark plug, checked the air filter (it is clean), gas...


Unable to crank? Do you mean unable to start?

If you leave gasoline inside tank over long period of time, that will 'gum-up' and ruin carburetor.
To prevent problem, put additive in gasoline or empty gas from tank:: under gas tank should be a hex bolt that holds up gas filter > loosen bolt and drain gas.

Starting the engine:
Take off air filter and spray WD-40 directly into carburetor.
Start engine, engine should fire on the WD-40 accelerant.
If engine fires but does not keep running, try spraying WD-40 into carburetor continuously to see if you can keep engine going.
If engine stops each time after it no longer gets WD-40, then carburetor is bad or gasoline not getting to carburetor or gasoline is bad.
Try fresh gasoline.
Do not turn small engine on side or upside down or oil will get into carburetor.

Check gas supply: Go to gas filter under gas tank. Pull loose rubber hose that connects to carburetor and see if gas comes out rubber hose.
If gas is flowing to carburetor, then carburetor is gummed up.
Small engine repair might suggest 'gum out' or have other suggestions ... but you may need a new carburetor

If engine will not fire on WD-40
If engine will not fire on WD-40 at all, then spark coil may be bad or exhaust port is clogged
Check screen that covers exhaust >> is it covered with carbon and dirt or can air pass through it easily?
Check spark
Remove spark plug
Put spark wire back on spark plug
Hold spark plug by rubber spark cap so hands don't touch metal part of spark plug
Touch spark plug threads against hole where spark plug was removed >>> metal to metal so it conducts electricity
Pull start cord and look for sparking between spark plug threads and metal of engine (don't look at the spark gap ... look where metal meets metal
If you have no spark, the spark coil is bad >> time for estimate from small engine repair shop or get your part number and order replacement

Engine will turn over, won't fire


There are only 2 things to make it fire: having fuel and having spark. Pull out one plug and have a helper to start the engine while you hold the spark plug touching the engine chassis to see if it sparks. If there is then open the air filter to put some of fuel in tho start. It if is starts then you know what the problem is. No spark, look for problem at the ignition coil , rotor and distributor cap. No fuel , look for problem the fuel pump relay behind the battery. Good luck.

'99 silverado will turn over but won't start. I have a new battery, 6 month old starter, new plugs, new distributor cap and rotary button. I used to be able to turn the ignition on and off real quick and...


I'd start with one of these and move on to the next.

Fuel
Spark.

Is it getting fuel? You should have an "in tank" electric fuel pump. When you turn the key halfway (just before turning the engine/starter over), you should hear the fuel pump prime. Easy way to check is to look in the throttle body while someone turns the key to the "on" position. You should see/smell the fuel. You can also listen to the gas tank while the key gets turned. You should hear the fuel pump run.

To check spark, pull a spark plug out, put it back on the plug wire and rest the electrode end of the plug up against the engine or exhaust manifold and have someone turn the engine over. You should see the spark plug firing. Don't hold the plug or wire while doing this. You'll get zapped if it's working ok.

If these both check out ok, then take a look at your firing order. If it's off by a significant amount, it may not fire. I've seen this happen when a cap/rotor/wires were changed and the wire/rotor was not positioned on the correct cylinder. (Most of the time they will at least fire or backfire, but either not stay running or run REALLY badly if the firing order is off.

What is the firing order for the 1994 ford taurus 3.8 engine, have just replaced cap and rotor, need order, thought I marked them but engine will not start. Perhaps I was wrong in the order.


Not trying to insult your intelligence, I'm going to get pretty basic here,

Looking at the Front of the engine, the spark plug order is 1, 2, 3, and 4. Front to back.

Looking at the distributor, it has two mounting screws for the distributor cap. One is close to the engine, the other screw is on the other side.

Looking at the distributor cap screw, on the Far side away from the engine, Number 1 spark plug is on the tower to the Left of it.

To the right of this distributor cap screw, is Number 2 spark plug tower.
The rotor turns clockwise.

Again, looking at the distributor from a top view, there is a distributor cap screw at the top, (Close to engine), and a distributor cap screw at the bottom.

Drawing an imaginary line from the top screw to the bottom screw, Number 1 spark plug wire goes to the Left, of the bottom mounting screw.

Firing Order is 1-3-4-2
The rotor turns Clockwise, (To the right)

Jonsered 4036 chain saw shows fire at spark plug won't fire.


Brake cleaner might not be the best choice for test firing... Pick up a can of Starting Fluid and spray a VERY SMALL amount into the air filter...
If it still doesn't turn over the engine might be worn out/damaged internally... At this point I'd compression test the engine and if the compression is lower then 80-90PSI It would be time to get a new saw.. If you can't get you hands on a compression tester you might want to take it to a Lawn and Garden shop and have them look at it..

If it does turn over with the Starting Fluid you looking at a fuel problem and I'd start with changing the gas with a fresh can and checking the (fuel filter) <-- found in fuel tank...


It will run with the bar off..

The brake only stops the chain and has nothing to do with the spark...

Hope this helps..
