[arnie]

advise please. from cold it starts fine but when warm it takes about 20-30 seconds. its as if its out of fuel, we took it to a garage today and they quoted £300 to supply and fit new diesel injectors. can anybody tell me if this is the problem. ive seen a similar post on here but there was no replies, i was hopeing for some advise before going ahead with the work.

any help appriciated, simon.

How do they figure it needs new injectors. What checks did they do?
For the cost you quoted there ie £300. That sounds very very cheap. Those injectors are probably £200 each!!

it runs great and plenty of power. but when you turn it off it won't start again untill it gets cold, we've had it on a diagnostic machine the result was no faults found. also had the injectors cheaked (pressure tested). from cold it starts fine, but a short trip to the shops it nearly flatens the battrey before it eventually starts.

any help is much appritiated.

does anybody know what this problem could be. we've had it on 2 machines both say no faults found. fitted new injectors and still the same. car runs great when it eventually starts.

never seem to get replys on here.

Have you had a second opinion on the diagnostic?

If its still showing no fault then the problem must surely be a basic mechanical one?

One which is made worse with heat / warmth.

Is something expanding with the heat and blocking or restricting something perhaps?

Are the injectors good? £300 seems too cheap, even for recons.

its been on 2 machines both say no faults found. we've fitted new heater plugs, had the injectors pressure tested, new cam and crank sensors and its still the same. dads on about scrapping it now.

What machines were used? Have you seen the fact there are no codes. It would be total guess work to identify the injectors based on nothing. Not to mention there are many places that will plug a car in and just take the money. Fault code diagnostics is not the only way to find a fault. You need to make the most of the live data readings from the ecu when the car wont start. I have experienced this with a renault espace DCI. Never kept the car long enough to check for the fault fully. The problem with it was it would loose pulse duration to the injectors upon cranking for ages and then would kick in.
