Intermittant starting problem,
05. May 2011 at 16:16

Problem starting sometimes,engine cranks over,plenty of battery power,but will not fire.
Seems that there is no fuel geting through,but if I bump start it,it fires up straight away,I'm pulling my hair out trying to suss out the fault.
Like I said this only happens now and then,its really a pain in the butt trying to pin it down,no engine management lights on.
Could it be the fuel pump? .

If it is a hot engine and diesel, it could well be hot start issue... If it is anytime (either petrol or diesel), then get your codes (paperclip trick in maintenance guides) and expect to see code 19 for the crank sensor...

Crank sensor was replaced about 2 yrs ago,no smell of petrol when it refuse's to fire,hot or cold no different.As I said it only happens now and then.
I'll try the paperclip test over the weekend,I've never done that before through.
It only needs a tow a few yards before it starts,so it's really baffling me.
Thanks for suggestions
Alfie.
