Morning chaps

its been a few days since i have had the rs on the road and now i am having an issue with the car starting After any short or long journey. We had this issue before the new alternator was fitted. We found that the car wouldnt start altogether due to a faulty bulb in the dash clocks!!! got it all sorted and Since we put that on it wouldnt start after i got it back home so had to get it bump started and took it for a long drive. the next day it was fine. I have just nipped down to get some petrol at work and low and behold the car wont start so again had to get it bump started to get back.

I have done some reading here and there and noticed the subject of the starter motor overheating?? possibly something to do with brushes or a solenoid?? I wouldnt be too bothered if it didnt start after a few minutes but last night i had to wait over 20 minutes after having a quick stop to replace a tail light bulb before it eventually got going again. Im dreading going to fill the car up for petrol as i can see it pissing a lot of people off!!!!

the engine has just been fully rebuilt and is on 170 miles of its running in at the moment. going to buy a new starter motor on saturday and see if that helps. If anyone else can shed some light on the matter i would most appreciate it.

thanks all

Get yourself a test light or voltmeter and next time it doesnt start, get someone to crank it while you check to see whether you are getting voltage at the solenoid exciter wire. If so, and it still isnt starting check the main cable from the battery is good and making a proper connection and the same with all the engine earths.

Its worth checking all these things first before you condemn the starter. You cound replace the starter and still have the same issues.

I don't know how accessible the starter is on the car but if you can just bridge the input and output,(two large 13mm nuts) with a 50p piece this will spin the starter but not engage it, so engine won't turn.
the old trick sometimes works of just whacking the starter with a hammer etc, this often jars it into life if it is sticky.
It is the case that these do suffer overheating due to close proximity to the exhaust manifold, but if running in, and not ragging it should be ok for this.
The actual starter faults are normally either worn brushes, or laquer peeling off inside surface of the solenoid housing and physically jamming the actuator rod/piston.
A old bit of knackered 100 grit oiled up can be used to clean the inside of the surface to sort this problem.
If it's brushes it's still dead easy to do, but if it's had a hard life might as well get a recon.
As said though check all leads etc, especially earth connections.

Crank sensor, not producing enough voltage to trigger coil when hot..hence when you bump start it, engine turns faster, more voltage, fires the coil. either a crank sensor issue or a cranking speed issue
