Astra 1.7TD - Faulty Fuel Pump? - Skell
I have problems when accelerating over 70mph, driving with a load, or with less than 1/4 tank of diesel. Car hesitates, looses power and goes into limp mode. Occasionally ECU light comes on but no fault codes are showing. Local dealer changed the MAF but problem is still there.

I think it may be the fuel pump as my MPG is also getting worse. Usually a tank will do 530 but struggled to get 510 miles out of it this time with same driving conditions. Car had done 73,000 miles.

Anyone else had this problem?
