Car cut off and will not start

Since spraying starting fluid in the car it runs, tells you that the problem is fuel related. You need to check the fuel system step by step completely. It seems you have done some of the checks already, but you don't say weather you checked if you get fuel on both sides of the fuel filter. If you only get fuel on the inlet side and not the outlet, your fuel filter is clogged, so replace it and recheck. If no fuel on either side and you say the fuel pump works check the fuel pump relay. Don't just replace the computer before all checks are made the relay, fuse and grounds, etc. This can be tiresome but can also save alot of money if you check system and don't skip steps you'll find your problem.

Might want to check the anti-theft security system. do a google and you will find many articles describing how you can splice in resistors that match the ohm of the chip in your key. I believe the anti-theft system disables the starter and fuel pump

Ok, so because the car starts on starting fluid we know the problem lies in the fuel system. You need to check the fuel pressure in the fuel rail because if there is insufficient pressure when the injectors open no fuel will be sprayed out. If you press the little schrader valve on the test fitting on the fuel rail you should get a little instantaneous squirt. If you can hire a pressure test gauge from a shop that would be great but the alternative would be to use a small pressure gauge from an air regulator or anything you can find with the same thread. If you screw in a pressure gauge remember to take out the valve core first. You should have something like 35 to 40 psi. If you don't have fuel pressure when the pump has run, suspect the fuel pressure regulator. You should also have a flow of fuel in the line going to the regulator (dont confuse the return line though). If you have the fuel pressure the next thing to do is make sure the injectors are being pulsed. You can do this by unplugging the injector connector plugging in a noid light. You can get one of these at the auto parts shop for about $20 and it flashes when the injector is pulsed. This should be enough for the time being....report back and I will help further if I can.

The Method with the Starter Fluid, Diagnosed your broblem. This Showed that ENGINE NEEDED Fuel to Start and You need to Replace the FUEL PUMP. BUT BEFORE you Do BE SURE That the Fuel Pump RELAY is Working Properly , This is When You Check for POWER @ FUEL PUMP with a TEST Light, The PINK WIRE W/ Black Stripe is the Power Lead To Pump IF YOU DO HAVE POWER AT THE PINK WIRE The Fuel Pump IS BAD.
