When you say nothing, is the engine at least cranking? If so, see if it starts with staring fluid for a couple seconds. If it does, the problem is fuel related. If it does not, then check to see if there is spark to the plugs. At least that way you will know which system to focus on first.

Tried starting fluid. No good. Checking plugs tomorrow. And yes it turns over fine. Something just quit working. I drove it to the store and when I got back in. It started and shut off.

If the sensors shut off fuel system, how does it know when I have fixed the problem?

If it doesn't start with starting fluid, then it is ignition related and not fuel. Check to see if you are getting spark. Let me know what you find. Also, if there is spark, make sure it is a blue snapping spark and not orange or white in color.

When you hear the click is the engine cranking over?

It sounds like the starter has gone bad. Lets use a test light and see if the starter solenoid receives a signal when the ignition key is in the crank position.

This guide will show you how check out toward the bottom.

Please let us know what happens.

No. Starter works great. Engine turns over easily. Just no ignition. Jumped fuel pump because lines are dry. Next I'll jump the pump relay.I have no diagnostic tools so doing it old school

When engine stalled, are you able to restart immediately?
Does keeping your foot on the accelerator pedal keep engine running?
Any repairs carried prior to this occurring?
Which engine do you have?

Can you keep it running with starting fluid? If so, it isn't getting fuel or proper fuel pressure. Since you replace the pump, have you checked fuel pressure? Are you sure there isn't a problem with the fuel pressure regulator?

So I can start my car fine and drive it but when I turn it off I can't restart it for at least an hour because it won't start. It will sound like it is starting but then won't. I have noticed lights on the dash and the cig lighter quit working so i think its electrical but how do i check that?
PLease help

Does the engine turn over and not start or does it not turn over until it cools down?

Only after I have already started it successfully and then turned it off and thats when it sounds like it is turning but yet does not start. I am afraid it is something that I won't be able to fix. I am pregnant and need a reliable car and hopefully this is something i can fix so it won't cost a fortune.

Unfortunatly Brandi, you are going to have to do some testing under the hood to find out why it wont start if it is cranking.Need to see if it has spark and fuel pressure to figure out where to start.

Normally diagnostic will be around 1 hour of shop labor, and if you have them repair it they will blend it in with the cost of the repair
