Re: cranks but no start
Yes there is a fuel regulator but i will recomend you to inspect and or replace fuel pump relay, and fuel pump fuse, also have some one to be close to the fuel tank and turn the ignition switch on, he or she should be hable to hear the fuel pump coming on for 2 or three seconds, if not there is an electrical problem, posible fuse, or relay, but if it does then repace the ignition module inside the distribuitor

Check all fuses first, then with an assistant, check for spark with a spark tester. if there is spark at 2 plugs, check for fuel pressure at the fuel rail with a gauge. Engines need three things to run, fuel, spark, and compression. If there is spark and fuel, do a compression test, if the timing belt jumped/broke, you won't have any
starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi
Signs of a Bad Fuel Pressure Regulator the vehicle will not start, if a bad regulator. Usually, this is a problem that is encountered in the morning when you start your vehicle. Many a times, the engine starts, but stalls shortly after starting. check the fuse and relay for pump. also remove line to fuel pressure regulator and if fuel in line, replace fuel pressure regulator. check for spark and also the timing belt. its one sign of not starting. if car runs fine on spray, I would not say its the timing belt or chain.
It's all process of elimination. Since you checked fuses, first thing I would do is spray some starting fluid in the intake hose to see if the engine starts for a few seconds. If it does you know it's fuel related. Meaning not getting fuel for any reason. You replaced the pump, but perhaps the pump is not getting power... or the fuel pressure regulator is bad, or the filter is clogged. If the engine DOES NOT start when spraying starting fluid in the intake, then you know it's ignition or ECU related. Start there and report back to us.
I think you should check the air filter or air intake. It seems like it's not gettin and air to start since when you spray the starting fluid it's runs but stop and it stalls. I think that it's the air supply for the car.
more than likely your fuel pump went out. it's in the tank. you can try spraying carb cleaner in your throttle body and have someone crank it. spray small amount of carb cleaner beware of backfire. do not acclerate while cranking. if vehicle turns on its your fuel pump
