Car will not start after cleaning corrosion off terminals
I have the same problem, i first notice some corrosion on my terminals and decides to clean them. After cleaning them and reinstalling the old battery, the car wouldnt start and no sign of power. The next day I went and bought a new battery and there was sign of power but the car didn't start. Went to autozone to get the old and new one check and both test good and they gave me back my old one. Put the old one back in and again no start, got the car jump and it start. HOORAY, no not really, decide to drive around the block, as soon as I turn the corner the car shut off. Then attempted to put the car in neutral to move it somewhere out of traffic, the shifter was stuck and could not move it into neutral. Then I jump started it again and again it start, let it run for about 20 mins and cut if off, thenr retried to restart, again No LUCk. Is it a battery problem only or could it be worst?

Take the car, or the battery, to a car parts store and have it tested. Usually the problem is a bad battery, unless it is a problem of corrosion on the terminals.
Understand that corrosion can not only prevent starting, it can prevent the battery from taking a charge to recharge it from the starting draw.
The terminals must be not only clean, but "metal-shiny-bright :" on the posts and the terminals themselves.
God bless your efforts.
if you had corroded battery terminal look around the battery +ve terminal to see if there is another smaller guage wire that may have corroded through and fallen off. The big cable you cleaned powers the starter , the other wire powers the ignition and may need connecting.
Aftermarket parts houses have replacement battery cables for some cars. For other cars, there are replacement battery cable terminal ends available. You cut the existing terminal off of the battery cable and the replacement terminal will clamp on to the end of the cable with bolts.
NOTE: Nothing on your car works without the battery. I have had many vehicles towed into my shop because of improper cable end replacements. Make sure the connections are clean and tight and free of corrosion.
The battery could be charged... how do the terminal connections on the battery look? Are they clean? Is there signs of corrosion? I would remove the battery terminals and clean them with a battery terminal cleaning brush... even a light coat of corrosion can screw up your electical connection and the "click" can be from not a good solid clean connection. One trick in a pinch situation I've had success is to take a small sheetrock screw and screw it into the crack between the battery terminal post and the battery connector.... if this improves the situation, then pull the battery terminals and clean them. Also make sure the battery ground is properly connected at the other end of the ground cable (usually the negative on the batt).
If for some reason your batt is fine, and the starter is just unable to turn the car over due to possible tightness of the motor from sitting, take the spark plugs out and squirt some Dexron type trans fluid in the cylinders... not too much but enough to coat the top of the piston and soak around the rings... let it soak overnight and then try to turn the engine over with the plugs out... ... let me know what you find... hope this solves your issue. let me know after. k
Just try to keep the gas and drive for at leat 15 min HWY if possible. Yes, it will turn off if you let go the gas, but it will restart and stay on as long as you press on gas. Just keep on driving and the computer will readjust the emission inputs and will get back to normal.
POSSIBLY STARTER MOTOR SOLENOID WORKING OF AND ON INTERMITTENTLY OR DIRTY TERMINALS ALSO CHECK BATTERY TERMINALS ARE CLEAN AND TIGHT IF BATTERY TERMINALS ARE ALL GREEN WITH CORROSION CLEAN WITH HOT SOAPY WATER SMEAR WITH VASOLINE AND WHILE AT BATTERY CHECK WATER LEVEL INSIDE AND TOP UP JUST SO INTERNAL PLATES ARE COVERD HOPE THIS HELPS GLENN
