Intermittent loss of power P38 Diesel 1995

Intermittent loss of power P38 Diesel 1995

Hi all,

Any ideas or help would be very much appreciated, on my much 1995 P38 Diesel.

I have a intermittent loss of power, as like running out of fuel, suddenly your driving nicely a long and lose all power at the throttle peddle? Cars still ticks over, and if I wait a while some times it just comes back and all it well until the next time it goes, I have just change the throttle actuator on the throttle peddle at the cost of £250? As I thought it might be that, by after fitting it I had only driven about 15 miles and back came the fault, so I guess there goes £250 replacing a part that was ok? I wonder could it be the ECU. And if it is, could I just replace it for a second hand one? Or could it be the faulty pump? Not sure what make it is on mine but the throttle actuator was Bosch just wonder if any has the same thing happen to them or knows any else that has

Many thanks Mike

have you tried changing the fuel filter as a first step.

Could be something simple like a blocked breather to the fuel tank creating a vacuum, Slack off the filler cap and see if you get the same problem. A blocked filter or pipe at the tank will produce this kind of problem, I have found bits or rag in tanks!! Also sometimes bacterial growth in the tank causes a black sludge that blocks the fuel pipe. Go for the cheap and simple first. Duff in tank pump is a known problem. Then there is the the needle lift sensor on number 4 injector etc etc etc before you get to the injector pump.
