diesel will not start.

i have a small problem with my v reg diesel rover 75,after a run when you stop the car say to fuel up or go shopping etc.on the very odd occasion the engine will not re-start and you have to wait 5-10 mins.then it will start and run fine.i have just serviced it so it has all new filters.any ideas please,many thanks.

Dodgy fuel pump perhaps

trebor · 1st October 2009, 07:16

could be the fuel pumps as said but poor warm starting on a diesel normally points to the cam sensor, cost around £60 from memory, and easy to fit yourself, located just under the engine cover.

Cam sensor or under bonnet pump, but I'd plump for the sensor.....

Easy way to check, is if the car won't start, take it out, pop it in the freezer to chill it and try again.

Your symptoms seem identical to those I had with my previous 75 and it turned out to be the cam sensor.

Best place to start I'd suggest.

I had this problem also changed cam sensor 2 weeks ago and no problem yet. Sensor cost me £65 and is dead easy to change. good luck.

If it's not any of above, almost certainly one or more of your injectors are suffering from "leakback"

Aye, have to agree with Jules. Alan at Lynx Diesels refurbed my injectors and did a great job. So if it turns out to be a 'leakback' problem, give alan a ring. He's helped a few out on the forum.

Cheers, JRT.

have a look at rover rons site zthome, this will tell you how to check for leak back , rather than trying this and that

thanks everyone for the advice.if the wife will let me have £65 i think that i will try the cam sensor first and see what if that cures the problem.:lol:
