Motor turns over but won't start

Only two things can cause this (1) not getting gas and or (2) not getting spark.
Have someone crank while you hold spark plug wire just of off spark plug, if you see spark from wire too motor block then put a little gas into carb and see if it fires if it fires then look for a gas line or gas tank problem.

may have a air blockage in fuel line take one of the plugs out and add couple drops of gas try again.

Your factory motor is the 3800 V-6 for your model. You can get the firing order from your local parts store...(Auto Zone will print this for you for free) then you just need to identify the #1 cylinder spark plug and follow the firing order...if you have a friend with the GM 3800 V-6 (popular GM motor) you can also compare the firing order (plug wires) Hope this helps.

ok, turning over and cranking are the same thing, what your saying is it won't fire, so , 2 things make a motor fire, electric and fuel, so starting with the easiest remedy , remove the distributor cap, and inspect the rotor and connection points that are inside the cap, check for any debris built up , sometimes you can clean them good enough to get the car to fire up, if it does , normally you would replace them , ( not that expensive) remove the number one cylinder spark plug, and once out put the spark plug wire back on it, ( your going to need help with this step) with insulated pliers , hold the plug and place the bottom of the plug against a grounding point (any bolt on the motor will do,, but try and keep it away from the carb as its Hopefully going to spark) have someone try and turn the car over as if to start it, look for spark at the end of the plug, if you have spark,, replace the plug and try and start the car , if it won't,, move onto the fuel problem, you need to make sure that the car is getting fuel, remove the fuel line to the carb turn the key for a second, you should see fuel splashing out, if yes ,, you should be able to start the car , if no,, check the fuel filter first , then the fuel pump,

Have you checked for spark first? Sometimes a car won't start due to no spark. This condition is usually caused by: Security system, bad ignition module, crankshaft sensor, camshaft sensor. You check it by pulling a plug wire and putting a screwdriver in the wire to see if it arcs. If it is getting fire look for the fuel pressure release valve usually located on the fuel rail, looks like a tire valve stem. If it shoots out gas, and you hear the fuel pump prime, check the fuel pressure regulator. It could also be the timing. There are four things needed for a car to start: fuel, spark, timing, compression. As for your question, as far as I know there is one fuel pump, you have to drop the tank to fix it. Hope this helps.

When it ran out of fuel there may have been damage to the fuel lines. I would suggest getting it looked at by a mechanic to be safe

Did you do a tune up on the vechicle? Does it sound like it wants to start? It could be the spark plugs.

Sorry about you luck. but here goes how to check it. Pour a little gas in the air inlet ( take the hose off the thriolle body.) crank it and you got fire up briefly then you know you got spart but no fuel. If it runs the fuel pump and the amount of gas in the tank are to be checked. Fuel pump fuses and relays, amount of gas in the tank. Let's say it didn't do nothing but crank, Maybe it doesn't have spark. Take a plug wire off the easies plug you can get to put an old plug or a screwdirver in the end of the wire lay it on metal and crnk it and watch for spark. ( don't hold it in your hand as if it is working it's shock you bad enough to kill you, In the worst case) You see spark and it still won't flash start with extra fuel added. Then you'll have to take a plug out to see whats going on in there. With the plug out it could be soaked with gas, antifrezze, oil, or anything else under the sun. But it could be dry and normal looking too. Test this plug in the end of the wire laying on the exhaust maniflod. If no spark your back to that or it sparks your back to gas. But let's say you still can't get it to pop off any. Maybe it over heated and the engine has little or no compression. ( with the plug wire and the plug out of the way put your finger over the hole the plug came out of and crank the motor if it blows your finger out hard its good but if you can hold it it's bad) ( blown engine ) Your not done yet ,! Put a little motor oil in the plug hole and crank it again if the pressure picks up lot it might start if you do the same to all the cyclinders and then with it all put back together start it. (It'll smoke like crazy so be ready for that) But it still might nor start. The timing chain could have skipped and the timings off enough that it won't start. Most likly it doesn't have sprk and the dist. cap is behind the water pump and it's hard to check as you need to remove the water pump to get to it. The coil wire can be removed first though and check for spark at it. No spark and the dist is turning the crank senser and or the ingition module could have failed. Take the module off and that it to the auto parts store and they can test it and sell you a new one if its bad. If you find no spark first then get the module tested before you do anything else. If the crank senser is bad you can unplug it and cross the wires the are in the plug with a paper clip on off on off and the coil should fire with a good module and the key on. If it does change the senser and you have spark and it'll run if you put everthing back together right. The cap and rotor are bad about failing on this car and they're expensive. The coil wire will fire even with a bad cap and rotor so don't jump to this till you getr good spark at the coil and not at the spark plug. Coil wire can fail too. The cars old enough that all the parts are in question till their proven good.

Lots of reasoons for a no start this answer is as if it was running OK just the other day and was starting OK. The gas tank has gas? Spinning real freely indicates to me that the timing belt broke. The oil cap off the valve cover look in there to see the cam and crank engine you should see it turn. The fuel pump may not be coming on. The fuel filter could be frozen not letting the gas go though. The spark may not be happening as A senser or also a plug wire or other wire off inspection of these things something off can be the only problem

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.
