chimaera 450 somtimes wont start

[collingbroon]

I have a chimaera 450 98 which is working well apart from when it wont start.
It seems to only happen when its warm, i can put the immob off and can hear the pump prime but when i turn the key nothing happens doesnt even turn over, if i leave it for about 20 mins she starts no problem. It doesnt do it all the time just now and again.

Anyone got any ideas?

Might be worth fitting the Modwise hot start kit plenty of info on here about it

I've just had this on my 450. Ut was an early warning sign for the starter motor packing up. I've now replaced it and fitted the mod wise hot start kit.

I have got the Modwise kit fitted and my starter was replaced by a Dream Machines about 2 years and 15000 miles ago. Battery is a Bosch one about 18 months old which is connected to an Accumate when in my garage.
It always belts over quickly on the starter when cold. Today after a run and having been turned off for about 5 minutes the starter turned very slowly then suddenly went faster and it fired up. Not the first time its done this, think I need to investigate it before it lets me down. No problems with the fuel pump priming.
Its a 2000 450.
So that would be the thick positive cable from the battery to the starter or the earth?
Won't have time to view this again today and off on hols to Italy tomorrow in the tin top (50mpg diesel sorry folks!). Hopefully some replies when I get back?

I had the same problem with mine. I would put money on the starter motor. When they get hot the armature in the motor expands and this stops it turning. I usually had to leave it for 20-30 minutes before it cooled down. The TVR garage advised me that this is a common problem, as the starter motor is close to the exhaust. They said they have tried to shield this in the past, but no joy. When I knew what was causing the problem it wasn't so bad. Although, it was a pain in the ass when it happened on the garage forecourt!!!

sorry to say that is not true, there would be smoke pouring out of the motor and cabling. Putting a relay BACK onto the selenoid circuit, the sucess rate is 99.9 percent on over 400 cars! I normally finish a topic so !!!!

If the motor itself had seized that's certainly true. But it could easily have happened to the solenoid (and people have reported clearance problems in the past which have been cured by a bit of careful sanding).
