My 1991 Chevrolet caprice classic sat for 5 years, and now wont start, it has a new battery. It turns but won't turn over. Checked oil, looks good..|||First off you are attempting to start the engine with 5 year old gasoline. Drain all of the fuel and add about 5 gallons of fresh gas. You may also want to change the fuel filter.





Yes, you siphon the fuel if you can. However some cars are difficult to get a siphon hose into the tank because of the baffles in the tank. If this is so with this car you may need to remove the fuel tank. However try to siphon first.





Gold Eagle makes a product called "Start Your Engines". This is a fuel additive intended to help start an engine that has been sitting for a long time. Read the instructions and add enough of this product to treat the 5 gallons of fuel you just added to your car. It may be a good idea to add this product to the fuel before you put the gas in the car so it can be properly mixed.





I believe the engine in this car is the throttle body style fuel injection. Remove the air filter cover and look at the fuel injectors located on top of the throttle body. Have someone crank the engine. Do you see fuel coming from the fuel injectors? If no fuel this will need to be investigated. Most likely either a problem with the fuel pump or the fuel injectors are plugged with dried fuel.





Make sure the engine is getting spark. Take a known good spark plug. Disconnect one of the spark plug wires and connect it to this good spark plug. Lay the plug on a metal piece of the engine where you can see the electrodes. Have someone crank the engine and see if there is a good strong spark. If there is no spark this will need to be checked.|||change plugs, wires, cap and rotor, and fuel filter any car that sits that long should have all this changed in addition you should also have the cooling system flushed and possibly the thermostat changed out since it sat there and rusted for 5 yrs, probably should change the belt too, its probably begin to dry rot|||The motor turns over but won't start? Get a mechanic if you can find one that wants to work on that POS.
