Check to make sure you installed the fuel filter in the right direction for flow, if the vehicle was working fine before hand then your problem is located in something you replaced, if not have the fuel pump checked for flow rate it may be starting to get weak and needs to be changed.
Can you hear the fuel pump hum when you turn the key to on? If it will start on starting fluid, you definitely have a fuel problem. The pump being stuck or bad, or the filter being plugged, or vapor lock (try loosening the fuel cap, does it pull in air?)
Your starter may be bad. Try hitting the starter. Use a long heavy screwdriver. Place it on the starter and wack it a good time with a hammer. If the brushes are bad this will make contact again. Try to start car. This may or may not work all of the time. Chances are your starter is bad and needs replaced.
Wait, first check the fuel pump, fuel filter and the ignition coils. If your fuel pump goes bad, it will start to heat up a lot and **** the voltage from your alternator, indirectly lower your battery voltage and can also be linked to coil failure. It will act up more when there is less than 1/4 gas in the tank. you can check the coils by getting a new or used coil and using the process of elimination (very rarely do all 3 go bad, if your car finally turns on and shakes so much that it feels as if will turn off but never does and your voltage goes way down then its at least 1 of your coils). The fuel filter should be changed if it hasn't been changed in the last year ( I recommend it for these cars as bad gas causes much damage) and check to see if fuel is getting to your engine. These cars also have fuel leaks around the front of the car especially where the 2 metal fuel lines meet under the front passenger side (the rubber connector wears out). If you're fuel pump is bad I then recommend changing your fuel pump relay as voltage and pressure will adjust. I hope this helps. Good luck
