Default HELP!!! Car not starting!!!

My 07 GT/CS stopped starting yesterday. Once I turn the key and push the clutch I get nothing! No Cranking or Clicking. The lights come on but that's about it. The only noise I'm hearing is a clicking from the fuse box under the hood.

I had the battery and starter tested. Both passed. Has anybody had this problem? Any info would be greatly appreciated!

How old is the battery? Did they do a load test or just check voltage?

Safety neutral switch could be faulty.

Have you tried either another battery, or just having jumper cables hooked up to be sure?

You said you heard a faint clicking sound from the BEC/BJB? That is likely the starter relay, if it clicks on when you hold it in start, then clicks back off when you let the key back to IGN then your fuses and such are fine at least up to the BEC/BJB.


1. (if you can verify that relay is going clicking on and off as I indicated, ignore this one)Workshop manual for diagnosing this(last page), Check the PATS indicator on the cluster.

PATS uses a visual anti-theft indicator located in
the instrument cluster. The indicator proves out for
3 seconds when the ignition key is in the ON or
START position under normal operation. If there is
a PATS concern, this indicator either flashes
rapidly or glows steadily when the ignition key is
turned to the ON or START position
. PATS also
flashes the anti-theft indicator every 2 seconds when
the ignition key is in the OFF position to act as a
visual theft deterrent.
2. After that, the manual refers you to 303-06.


Here is the starting/ignition system wiring diagram.
Whip out the owners manual for an easy to read diagram of the BEC and SJB fuses, first to check would be F4 in the BEC(30 amp), next F21 in the SJB(10 amp).

That should just about cover it...

If it's an original battery from 07 I don't care what test say replace it there is a better chance then not that is your issue.

Get a volt meter and check the battery voltage during cranking.
If it goes below 12Volts, I would suspect the battery.
Testing batteries can be done several ways.
Some are better than others. What method was
used when 'they' deemed it to be 'good'.
It it is an OEM 07 battery, I would replace it just because.
And they removed your starter and tested it and deemed it to be good as well?

Sounds like you have a bad relay in the BEC under the hood. It clicks
but does not send the voltage to the starter telling it to engage.

Get your owners manual out. Look for the relay and fuse placement
diagram for the BEC. Find Fuse 4 and the starting relay.
Check Fuse 4. Replace if bad. 30 Amp. Then swap the starter relay
with your fog light or cooling fan relay to troubleshoot the problem.

Guys! Thank you so much! So after hours of frustration I was able to get to the root of the problem. It was a combination of things..Bad Starter, Bad Relay and bad safety neutral switch...I was able to fix everything for under 200 bucks...my baby is back!

You stated you pressed the clutch in your first post, you don't actually have a safety neutral switch if you have a manual transmission..

Good to hear you got it working again, but I am still curious as to what the actual cause was, for future reference. Unless you're like the unluckiest SOB on the planet I'm doubting it was more than 1 of the things you list.

not if the relay in the fuse box is clicking. That relay is after the NSS.
