hi every one, i have a disco td5 that has a terrible starting problem, hard to explain all the problems but i will have a go.
when i go to start it from cold you can hear the fuel pump whining but the engine just keeps turning without firing, you can hear it trying to fire but with no effect, if you pump the peddle hard it then starts to fire and runs like a bag of s...! as great large clouds of smoke ( blackish) come from exhaust, sometimes you get better results not pumping the peddle or priming on key first, depending on the mood its in!!
its also a bugger to start when warm doing same thing and sometimes fine, or sometimes your running down road ok engine running well, then you have to brake and it will cut out and be a sod to start again, but as a rule when engine is running it goes like a dream, no power lose, sounds good and fuel consumption ok.
i have changed fuel pump/ sender unit, replaced washers and seal on injectors, had fault code readings checked with no problems, checked delivery pressure ( ok )
changed airflow sensor and checked all induction. i did have to take head of about a year ago and when putting back together i broke the fuel pressure regulator and had to replace this, and the problem started about a week later.
any help or ideas would be of help,
at your mercy, butcher boy.
