For about a month now, it has had a hard time starting. It would take a couple of tries and then work fine. Now you can crank it and it sounds like it wants to start but if you shoot starting fluid it wants to start. I already replaced the fuel filter. When it did start in the past the car would run just fine. The engine would idle really low and almost sound like it wanted to turn off

To determine if its fuel or spark issue-do below and see what happens

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
