One answer is lack of compression in the cylinders,normally associated with high miles.
could also be valve seats/spark plug gap/dirty air filter,there are a few more but start with the cheapest to diagnose and work up.....

2004 Chevy Van 2500 turns over but wont start

Try spraying starting fluid into the intake. Remove the air filter to do this. If it starts for a few seconds then you have a fuel delivery problem. If it does not, then you have an electrical problem with the ignition. there are 3 things needed for an engine to run if it turns over. Air, Gas, Spark (fire). No air filter solved the easy air issue. Add starting fluid answers the fuel issue. Only leaves spark after that.

My 93 plymouth laser wont start

If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.

If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.

If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.

In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.

2001 ford escape suddenly will not start. Battery good, sounds like engine turns over but will not start. What do I need to check next?

Does it try to start at all? Is the engine turning fast enough to start? Does the engine sound like it might be turning faster then it did before?

If the engine is turning over like it usually does, try spraying some starter fluid in the air intake to see if it'll run for a couple seconds on that. If it does, then you know you have a fuel issue.

If the engine is turning over faster then it did before, you probably have a broken timing belt.

If it doesn't run on the starter fluid, then check for spark. If it has spark then you probably have a broken timing belt.

Check these things first and I'll be able to help you more after you post the results of these trouble shooting tests.

My car runs great, but when i turn it off and try to drive it again in a minutes it wont start .i have to let it set for a while before it will start again

crank position sensor, camshaft position sensor or an injector with too many ohms resistance. when you turn the key to the on position you should hear the fuel pump come on for a few seconds. if not suspect fuel pump relay or fuel pump

you will need to determine if it's a no spark issue or a no fuel issue.

When the car wont start spray some carb cleaner or starter fluid into the intake and try to start. if it does start and run for a few second then the problem is with the ignition side

check for spark by removing a spark plug lead from a spark plug and putting a good spark plug in the wire, use a jumper cable and clamp one end to the spark pug thread and the other to battery ground. Turn the engine over and you should see spark.

is the check engine light on? if so get the computer scanned, autozone will do it for free

I have a 1999 gmc Yukon it is getting fuel and spark i even sprayed starter fluid in the intake but it still wont start it turns over good but wont start

ok make sure you have good fuel pressure
you must have good spark must fire a spark tester
if all that is good then check compression
and don't use STARTER FLUID on a GAS ENGINE it can blow a hole through the piston
hope this helps

1995 Jeep grand cherokee, drove fine yesterday. No signs of anything wrong. Now this a.m. starter engaged and everything seemed fine, but would not ignite and turn over.

The engine needs 3 things to run: fuel, spark and compression. It is most likely either no spark or no fuel. You can check the spark by taking out one of the spark plugs and ground it out on a piece of metal on the engine. Have someone crank the engine and watch the spark plug for a blue spark. It is easier to see if it is in the shade or it is dark. One way to check to see if it is a problem with no fuel is to get a can of starting fluid. Gain access to the intake by taking out the air cleaner. Spray a shot or 2 of the starting fluid in the intake while someone cranks the engine. Don't keep spraying the starting fluid for a long time because it can wash the oil off of the cylinder walls. If the engine is getting spark but no fuel, the starting fluid will cause the engine to run for a few seconds. If it runs for any time at all then you will know that there is spark and the problem is with the fuel system. After you determine if it is a spark or fuel problem you will have to diagnose what part of the system is causing your problem.
