Car will not start, however will start with starter fluid?

Hello,

It sounds like you might have an issue with fuel delivery to the engine. It could be the cause of a faulty fuel pump, fuel pressure regulator or a clog in the fuel line.
Can you hear your fuel pump come on when you turn the key to the on position?
If you can hear the pump then you know the pump is getting power. So the issue can be a clog in the line or a bad regulator.
If you cannot hear the pump come on, then it could be a bad pump or an electrical issue like a faulty relay or module.

There are 2 relays for the fuel system. One is for the fuel pump. It is located in the fuse box inside the trunk. The second one is for the fuel injectors. It is located in the under hood fuse box
