Hi. I have a 2003 Pontiac vibe with a new battery and starter it has been running great but for some reason now it won't start all of the dash lights up and I hear a slight click but it doesn't turn over everything that I read and every place that I have talked to says it's the battery starter or relay but their all good please help if possible I bought the car new and it's been a great runner but this issue has me banging my head on the wall.

Thank you for your time.

Update the problem with a bad ignition switch thanks all for the help

Update the problem with a bad ignition switch thanks all for the help

Thanks for posting back with the fix!

With a No Crank I like to start troubleshooting at the Starter Relay because you can split the circuit in 2. The Load Side and the Control Side. 

Knowing which side of the circuit is causing trouble really helps to narrow it down.

You know where your starter relay is and the easiest way to get to it is to pry off the vent plate (it's just clipped in) and access it through there.

Like I said, now you can split the circuit in 2 and this is what it looks like that way.

(I highlighted the Load Side in Violet and the Control Side in Blue)

((I don't agree with those starter relay pin assignments in the diagram but that doesn't matter. The wiring is correct so I'll refer to those relay pins as labeled))

Grab a test light, hook its alligator clip to good ground, pop out that relay and begin probing those 4 relay sockets.

The one labeled #2 in the wiring diagram will have power at all times from the 30A Main Fuse. Use your test light to probe all 4 relay socket terminals. The socket that lights the test light will be #2.

If none of the relay sockets have power then check for Power on the "Violet Side" of the diagram at that 30A Main Fuse)

The one labeled #5 in the diagram will have Power with the transmission in Neutral and the key HELD in the START Position. Use your test light to determine which of the remaining 3 relay socket terminals is that one.

If none of those remaining 3 relay sockets light the test light with the key in Start begin looking at the components on the "Blue Side" of the wiring diagram. (15A AM2 fuse, Ignition Switch, Park/Neutral Position Switch).

The one labeled #3 in the diagram is the Ground for the Relay coil. It will be  the socket across from #5. Switch the Test Light's alligator clip to Power and probe that socket. The test light should light up. 

If the test light doesn't light up, you'll have to check Ground Point G200 on the "Blue Side" of the wiring diagram.

The one labeled #1 in the diagram will be that last remaining relay socket. It will be opposite #2 and it goes to the Starter Solenoid.

But what if all the relay sockets check out ok? Then grab a piece of wire or a paperclip and jump relay sockets 1 and 2. If the Starter spins it's a bad Starter Relay.

If the Starter doesn't spin it's a problem on the "Violet Side". Battery, corroded (inside) battery cables causing voltage drop, poor battery cable connections (either Power or engine Ground), the wire going to the Starter Solenoid from relay socket #1, or the starter/solenoid.

 

edit: To explain why I don't believe the relay pin assignments in the diagram it's because it shows the Load Side of the relay on pins 1 & 2. 

But the Load Side is almost always on pins 3 & 5. 

The Control side (relay coil) is almost always on pins 1 & 2.

Sounds like you got a defective starter.

I took a voltage tester and checked

You need a load test. They're free at Autozone or a battery dealer.

Test the battery with a battery tester - if it is bad, replace the battery.

Or you can just try to jump start it, if it starts up when jumpstarted - it's the battery.

(Be careful if jumpstarting - follow the procedure as shown in the manual)

 

Scotty has a video on the subject:

 

And yes the Vibe is a good car, pretty much a Corolla.

Thanks for the help and sorry if bothering but I put in a new battery and still nothing so I took a voltage tester and checked the cable's and they were good also I forgot to add that about two weeks ago it did the same problem and I thought it might be a ground issue and all I did was kinda check it out and got into the car and it started it sat for maybe five minutes and fired up and has been running great until the it not starting now so I'm baffled please help in any way that you can. Thank you for your time

@dewhittier, see the excellent, detailed diagnostic procedures that @jack62 has already provided in this thread.

We’ll have you tried jumping the starter?
