I have gas in it and pretty sure that the battery is good, but the car will turn over but won’t start at all.

Hi,

A crank no start is usually the result of either a loss of ignition spark or fuel. Here is what I need you to do:

See if the engine will start with starting fluid. If it does and then stalls, we know it is fuel related. If there is no change, then we need to check for spark at the spark plugs.

Here is a link that explains how to check for spark:

If it does start with starting fluid, we need to check the fuel pump pressure. Here is a link that explains how that is done. You will need a fuel pressure gauge, but most parts stores will lend one to you.

Let me know what engine you have so I can get you the correct manufacturer's fuel pressure specifications. There were four options. See pic below.

Let me know.
