Fuel system problem?

[Psawangj90]

I have a 95 eclipse gs and I believe I have a fuel system problem. Long story short I hooked up my battery backwards rushing in 3 degree weather and fried the ecu. I replaced it and all the relays and blown fuses too. The car still wouldn't start. My dads friend is a "mechanic" although right now I wouldn't call him one since he can't figure out the problem plus sprayed starting fluid in the intake..which made the car start but it wouldn't stay running so I believe I have a fuel system problem. The fuel pump kicks on too. So i have no idea what it could be and yes it has gas in it. Please help!

I would check for spark and fuel. If you have fuel to the rail and spark and still no start then I would check the injectors.
