Hi Guys,
Have had a weird problem rear its ugly head recently. Details below:
-car will start 1st time every morning with no issues
-after driving the car and getting it up to normal operating temperature (oil temp 95C and above) the car will not restart once it has been shut off.
-the car will only restart after the oil temp has dropped into the min-high 80s
-with the ignition on and the clutch pedal in you can hear the starter relay click when the start button is pushed but the car does not turn over
I have done the following:
-replaced starter relays
-brand new starter motor installed
Has anyone else had the same issue ? If so what could it be?
thanks in advance
Dave

Re: Intermittent starting issue
Is the heat shield installed next to the starter motor? My mate had the same problem, changed the starter, still did it.
Then he installed the heat shield (which was somehow missing) and that fixed the problem.

Re: Intermittent starting issue
Sounds similar to the issue I had.
I've come to the conclusion that when the under bonnet temps are high, the amps on the starter wire from the ECU drop for some unknown reason.
You can start it by shorting the starter wire with the positive terminal, there's a connector right next to it. See pics.
For the time being, I've put a relay on the starter circuit which lets the starter pull the power from the positive terminal when starting.
Not a had a problem since.... touch wood...

Re: Intermittent starting issue
Just make sure you short the side of the connector that goes to the starter, not the ECU

Re: Intermittent starting issue
Morning,
I had a similar issue a while ago, does it have an aftermarket alarm fitted by any chance?

Re: Intermittent starting issue
Problem solved - replaced the starter cable from the plug at the battery terminals all the way to the starter solenoid, used extra heat sheilding and changed the location from where it was originally run near the headers. Have not had an issue since.
