roachy Posted October 31, 2010 Share Posted October 31, 2010 Im hoping for a bit of help please? My truck has been gradually losing power and has now got to the point where it struggles to climb over a house brick with 35"simex's. For a while its been struggling to do anymore than 50mph on the road and slows on hills. The engine was rebuilt by turner's approx 20000miles ago so should be strong, there's no smoke and its boosting well so its gotta be fuel. Ive removed the pickup strainer in the tank and fitted a new fuel filter, the lift pump is nearly new and it filled the filter up in no time so no probs there. It starts and runs well so i dont think the timing is out. Im thinking its got to be the FIP or injectors? anyone got any different ideas or know how to check these? thanks in advance Quote Link to comment Share on other sites More sharing options...

Other than that make sure no air leaks in fuel supply lines and renew leak off pipes. After that it gets expensive Quote Link to comment Share on other sites More sharing options...

cackshifter Posted October 31, 2010 Share Posted October 31, 2010 If you had a leak/blockage in the feed to the boost diaphragm or a duff diaphragm could that cause this ? The pump would think you had no boost even though you did. Its the pipe that runs from a connection at the turbo outlet to the pump.
