Battery is good, wont turn over

As long as engine turns over and starter proves good would suspect bad connection or corroded wires

has your car got a aftermarket security system ? sounds like the ignition and/or the fuel pump is being isolated by a security system fault

Can not nor should you jump a dead battery

You need a good battery or fully charge yours
& then check fuel pressure with a gauge at fuel
rail port

SOUND LIKE ALTERNATOR NOT CHARGING BATTERY.CHECK BATTERY VOLTAGE SHOULD BE 12.6 VOLTS.MAY SURE BATTERY CABLES CLEAN AND TIGHT.WITH ENGINE RUNNING CHECK ALTERNATOR OUT PUT AT BATTERY.SHOULD BE 13.5 - 14.5 VOLTS WITH ENGINE RUNNING.IF ALTERNATOR FUSE GOOD AND ALTERNATOR BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES OKAY NOT DAMAGED.DRIVE BELT NOT SLIPPING OR BELT TENSIONER NOT DAMAGED.ALTERNATOR MORE LIKELY FAULTY.TURN OFF RADIO FIRST.BEFORE REMOVING NEGATIVE BATTERY CABLE TO KEEP FROM LOSING RADIO CODE.

LIGHT ON IN THE THE GLOVE BOX,TRUNK,STUCK BREAK LIGHT SWITCH,,, LOOK AT IT AT NIGHT WHEN ITS GOOD DARK. OR IT COULD BE A BAD BATTERY

Cars that are idle for a long time are often difficult to start.

One solution is to tow them in gear (not so hard on the battery).

Was the battery checked before it was sold to you? Batteries will lose their charge over a period of time even when not hooked up. If you have a voltmeter it should read 12.8 volts on a fully charged battery.
Have you tried to boost the car with cables?
I suspect if the car was working OK 3 months ago it should start. Which leads me to suggest an undercharged battery.

Sir,

ou should put some marvel mystery oil in each cylinder and turn the engine over by hand.. Of course you have to remove all the plugs first and leave them out until you get the engine ready. let sit for an hour and repeat the process. Make sure the water and oil are changed. after you have repeated the oil in the cylinders three times. You are ready to try and start the engine. check all wiring and battery for proper function. turn the engine over with the starter. Replace the spark plugs (recommend new ones) and then try to start the engine.

The best way to start any engine that has been sitting for any time longer than a year is to flush the old gas out. Gas that has been sitting for too long will go bad unless a gas preservative was added to it. Then change the oil and the oil filter. The coolant in the engine block, and the radiator should be flush out, and only clean water she be added without the thermostat. A lot of sediment from the iron in the block and from the radiator will build up and the coolant. This a also a good time to examine all rubber parts for cracks or leaks. It's would also a good time to change the spark plugs and wires. Examine the carburetor make sure its that it free of debris spider webs or any thing else. It would ofnot hurt to change the fuel filter pre-carburetor. All this with a fresh battery, and lots of luck you're good to go.



Thanks
Good Luck

Appreciate to rate as "Fixya"

you need to try a new battery sounds like your battery has gone bad

Does it have a distributor??? If it does,take it off and spary the inside of the cap with WD-40. It sounds like you have moisture built up in the cap from just sitting there. You might also need to put a battry charger on the battery to bring it back up to fully charged. Cold weather sometimes play a tole on cars sitting around, especially Batterys.
