    my 66 'stang has the same problem, liquidss are topped off, new fuel filter(fuel is getting through just fine), new spark plugs, new spark wires, rotor, and distributor cap.

    engine will crank but wont start up....

    what else can it be?

    I have been having a similar problem in my 1966 mustang 289 2v. i rebuilt the carb, but that did not help. i have checked to make sure that the fuel pump works. we took it to a mechanic about a year ago before the problems started and im pretty sure they replaced the spark plugs and distributer. The car has always had a rough idle when its warming up. We don't start the car very ofte. When i try to start it, it turn over and tries to start. sometimes it wil start for about 30 seconds and then it dies. i was thinking it could be a fuel mixture problem.

Guide to starting a dead horse!
1- Spray a little starter fluid down the carbuerator. If it tries to fire, your timing and ignition is probably OK. This could indicate a carb or fuel pump problem.
2- If it doesn't fire, check out the points, condenser, coil, distributor cap and rotor. Look for condensation inside the cap. Check that the high tension wire from the coil to distributor is in good shape and not touching the engine or any brackets,etc.
3- Verify that your timing is correct. You may have a timing train problem (Worn or broken).
4- The distributor may have come loose and changed positions. Check for proper timing.
5- It may be a compression problem. If it has set long enough for the oil that coats the cylinder walls to drain down, you won't have enough compression to allow firing. Check your compression and if this seems to be the case, remove the spark plugs and squirt a little Marvel Mystery oil, or similar light weight oil into each cylinder. When it starts, it will smoke for a few minutes, but that will go away.
Hope this helps and if not, get back to me.
Have a super day!

You could clean out the carburator or it could mean that theres no oil or very little oil, and if it does have oil, try spraying carb cleaner in the opening in the carb, and then try to start it then rev it up for like 10 minutes to get everything moving again, then after that it should start right up. Another possibility is theres no spark, I would recomend replaceing the spark plugs (all of them not just one or two) Hope it helps!

There's two possibilities. No spark, or no fuel getting to cylinders.

I would change the plugs regardless. If you haven't driven it in a year and it was parked with fuel still in the carb. You will probably want to pull the carb and rebuild it. The old fuel is likely gummed up inside the carb.

The car wont start

You probably blew a headgasket and now there's water in the combustion chamber. It's a condition called hydrolock. You can't compress water and the engine won't turn over. Remove all the spark plugs and try turning the engine over for about 30 seconds. That should blow the water out thru the spark plug holes. Try jumping the battery with another car or get a car battery charger to juice up your battery.

1996 5 speed honda accord. sat for a year. put in new battery. everything lights up, but car wont start. never had previous problem.

Are you saying the car turns over (cranks) but it does not start? Or, the car is Not turning over?
If it is cranking over but not starting, and it ran fine before sitting for the year, it may be water/moisture in the gas. Try some dry gas, and/or Carb-fuel injection cleaner in your gas tank.

1966 Mustang won't start after sitting for 3 years - new battery

If engine wont turn over it wont do you any good to mess with the fuel filter or the carb. You didnt say if the car is an automatic or striaght stick if it is a automatic check the nutral switch on the transmission. car wont normally start if trasmission isnt in nutral or park. May want check the starter it may be drawing to much voltage

1966 mustang has not been driven for over a year. put new battery, water in radiator, gas. the engine turns over o.k. but it wont start. please help.

Did you check the oil? Often when it sits too long, it kinda gumms up from condensation in the engine, also check your alternator, and I would bet on your spark plugs. get the new platinum tipped ones, they last forever, you can get them at autozone, advanced, and probably good ole WalMart.Good luck.
