How do you know for sure its getting fuel through carb? You can usually see a squirt from the power pump when you step on the gas, but usually nothing else while you are just starting it.

Have you tried to putting a little gas in the carbs before you crank it? Not much and remember.... Its GAS.

You could also try some ether. Its safer and will help dry out a wet cylinder/sparkplug. Just don't use to much of it for to long. If it doen't fire with either then you need to recheck for spark on all the cylinders

Testimonial: "i pulled cleaned and rebuilt the carb, and i tried dumping a little gas down the carb and still nothing, i was told to mess with the distributor, the guy who sold me the truck said that was replaced, and said his mechanic said it was just the timing chain, but i replaced that, could it be possible i have the motor 180 degrees off of time?"

SOURCE: 93 geo tracker gets fuel, has spark, cranks but won't start

Since it gets spark and fuel I suspect the low compression to be a large factor. What is the compression in the other cylinders?

How did you test the Coil? with a test light see if the positive side of the low tension side of the coil is hot (12 volts with the key on) The other sde should be hot too till you crank it and the negitive side should flash the test light. if it doesn't remove the negitve wire from the coil and connect it to the test light and the other side of the test light to the positve with the coil unhooked the light should blink when cranking. if it does the coil is shorted and you need a new one. if it doesn't then the module is bad and on this car there is a ingtion power transsister. The distrubutor pickup is not out of the question either as the pickup makes the transsiter work. with the test light stil hooked up that did'nt flash but has 12 volts on the one wire, unplug the distrubuter ad use the test light to see if any of the wires come hot with the key on. If not your looking for an ingtion switch or fuse problem. he coil gets it's positve power from the same place so your looking for a broken wire if the coil is hot. You should be finding your problem following this way and the transsistor also has a wire thats hot with the key on with all the other wires connected on the coil and the dist. A rebuilt distbutor is cheaper than rebuilding your distbuter and and parts sore is going to have the distrubuter. the module is in the distbutor as is the pickup.

My1980 ford f150inline 6 wont run just trun oververy good

If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, check fuel system. If this is a carbed engine, usually the fuel pressure isn't very high. You can take fuel line loose from carb, aim into container, bump the starter a few times, see if gas comes out. If nothing comes out, check fuel pump and fuel lines.
5--7 psi is fuel pressure spec I've seen for 6 cylinder 1980 ford, carbed engine.

Car turns over but won't start. Boyfriend checked the spark plugs , says vetting spark. It says he did a compression check to it. Starter is a year old, battery new, we replaced fuel pump 3 weeks ago...

A thumb is not test for compression as 10lb/sq " will blow your thumb off. Have a proper compression test done. Next although it is sparking the question to ask is it sparking at the right time and to the right cylinder. Pouring fuel into the cylinder is a waste of time as the air/fuel ratio will be too rich to ignite even if the spark was occurring on the compression stroke. So here are some simple steps to follow to get it going
Have a compression test done to determine if there is sufficient compression to ignite the mixture
2 check that the spark is occurring at the cylinder at the right time ( no 1 cylinder on timing mark on compression stroke.)
3 . If it is EFI engine then check that the injectors are actually squirting if carby engine check that the fuel is in the fuel bowl With engines you have to have a combination of 3 things for the engine to work They are compression -which you will be checking for--2 spark timing--- which you will be checking for and lastly 3 fuel into the cylinder at the right time ==which you will be checking for
you only have to be missing one of these and you had best take it to a professional mechanic to get it started.

I have a toyota nadia d four engine with aproblem of not starting.changed pistons,valves,plugs,head gascket and oil.after that the car is cranking but not starting

If you give it time to cool off between starting attempts, it should hold up to it. If you use the starter for 15 seconds trying to start it, then give it a full minute to cool off before trying again.

Do you have compression in all cylinders? That and spark and gas is all a good-timed engine needs in order to run. Actually I would do it in this order: check for spark going to the spark plugs, if good, check that gas is getting into engine (carb or fuel injected? you would see gas coming out of either one- down the throat of the carburetor, or out the bottom of the fuel injector in a cone pattern, while cranking the engine over and watching). If spark and gas are good, then better check compression. See if your work really sealed the cylinder chambers. A compression test will verify this. Cause the next thing you will have to check is if the valve timing is right. You will need to make sure the timing marks are spot on. This may be a tedious job. Removing a few parts to check the timing marks.

So just remember, spark, gas, and compression. that's what the cylinders need to fire and run, but the timing has to be correct.

While drviing down freeway today the 2.5 ltr engine died and will crank but will not start. one month ago it was backfireing in intake and dieing on freeway and i thought i had bad gasoline it fixit

you need three main conponents for the engine to run,fuel,spark,compression . first have someone to crank the motor and put the spark plug lead of the plug and hold it near the block and if there is spark it will jump a inch or so, check the fuel filter , hold the fuel line clear of electirical and heat, crank engine , fuel will flow, when engine is running but running rough as a miss fire disconnect plug lead one at a time till you find missing cylinder

My 1987 dodge raider is having problems starting. Sometimes it seems like the car does not have enough power from the battery. It has the 2.6 four cylinder and is also fitted with a carb. It has been...

Check your fuses. Make sure the battery is good and the battery terminals are clean and the wires have no tears. Make sure your engine is getting gas. Spray gas or engine starter in the carb. If it starts for a second, it is a fuel problem. Either fuel pump, fuel pump fuse or relay, or clogged fuel filter. If this all checks out, you need to start looking at spark plugs, wires, distributor, cap, rotor. Check your timing belt and make sure it is not broke. It could be a cam sensor or crank sensor as well.

What is causing my 1986 jeep grand wagoneer engine to stall while driving? I cannot restart it but there is power. It will turn over but not start and there is gas in it. The jeep just went "poof" and died...

ok, its and old jeep, cranks but will not start.

carb fueled right? crank it wide open throttle to clean the flood
and block open the choke, if CARB has auto choke, if manual choke make sure its open. (push in knob... called choke)
fuses first. test them.
first check for spark in all cylinders.
if you have spark on all , then its flooded.
if no spark on one try a new spark plug and wire.
if all spark is dead , do the tuneup. now. all spark parts.
if spark is dead, check it at the coil, ? good there? or not.
that is a start.
if the carb is bad, we cant cover rebuilding it here.

stalls while driving has over 50 causes.
but bad spark or flooding tops list. (assumes engine is ok)

What coul be keeping my 1986 honda civic from starting? The plugs all spark, the fuel pump gives gas to the carb, Ive changed all plugs cap and rotor and have tried spraying starter fluid directly into...

It cranks really good sputters a little and makes some loud pops but it will not turn over? FYI:Cranking and turning over are the same thing. When was the last time it ran. The gas could be bad. Did you get new plug wires as well. Try testing the distributor, remove a spark plug, plug it back into the wire, and touch the threads to ground and crank the engine. It should spark. Keep your fingers away, that's high voltage. Remove all spark plugs, spray some starting fluid in each cylinder, then crank the engine with the plugs out. This will clean any debris from the cylinders. Engines need backpressure to run properly, a major exhaust leak hence the popping, could cause it to not run. If you can get it started try to keep it going, full throttle, keep in the starting fluid, it could just need to get warm. I used to have one of them and they don't like it when they're cold.
