Turns over but wont start. changed fuel pump, filter, plugs, cap and rotor. car been sitting for about 4 years before i bought it.also bought a new battery required for the car

Sounds like it could be a bad starter solenoid.

Check fuel pump fuel pressure , if no pressure change fuel pump .

Have you tried having the fuel inject.'s cleaned or replaced?
Or new distributor cap, plugs and wires?

fuel lines hook up backwards problem solved...

If it's been sitting for a year with the same fuel, drop the tank and flush it and the fuel lines completely. Also take out the fuel pump and replace the fuel pump screen and don't forget to replace the fuel filter as well. Fuel WILL go bad sitting for that long.

are you sure the wires were put on correctely?????

Here is a list. Bad timing,dirty air filter,cheap gas,old spark plugs,bad spark plug wires,bad fuel pump,bad fuel regulator,bad exhaust system meaning full of holes,dirty oil and oil filter,dirty fuel filter.

Change fuel filter, check air filter, if that doesnt help check fuel pump pressure and if you have more than 50,000 miles change spark plugs

Check your cold start injector, sit on top of intake.

You must have the plug leads in the wrong place on the distributor.
Firing order is 1-3-4-2
Remove the distributor cap. There is a tiny mark on the aluminum body where the cap sits on it. Turn the motor clockwise by hand until the rotor lines up with this mark. #1 plug lead should be in the distributor cap hole closest to the rotor in a clockwise direction.
If the motor still does not start rotate all the plug leads 180 Deg.
