Banjo Posted December 4, 2009 Share Posted December 4, 2009 Hi, I have two 300tdi's, one fires along sweet goes real well the other is gutless and carp. I've turned the fuel up but cannot get it to smoke (ie make power) for some reason its not getting enough fuel, now ive swapped injectors, ive checked all waste-gate pipes and inlet and boost pipes, the diaphragms been swapped, ive changed the filters and even run it up the road with a gery can for a fuel tank to eliminate the tank and nothings working. I've changed the lift pump but it still wont pull past 3k and its very slow and doesn't smoke ever, it starts on the button and is normal to drive just vv slow! Help! What are the symptoms of timing being out? Any other ideas? cheers Banj Quote Link to comment Share on other sites More sharing options...
BogMonster Posted December 4, 2009 Share Posted December 4, 2009 Are they both mechanical injection, both EDC, or one of each? Quote Link to comment Share on other sites More sharing options...
disco_al Posted December 4, 2009 Share Posted December 4, 2009 was it a brand new lift pump or just swapped from another one? Quote Link to comment Share on other sites More sharing options...
Timmy511 Posted December 4, 2009 Share Posted December 4, 2009 imo, its a fuel problem somwhere along the fuel line. when you rev hard it from tick over and then let your foot off the pedal does it seem as though its about to stall? if so check all the fuel lines and connections for leaks, theres a bowl filter on the chassis, these rot, get perforated and allow air into the system. this can also happen at the tank on the sender unit. wire brush all metal pipes and check for pitting, if it is pitted/rotten the chances are thats your problem.

JohnL Posted December 4, 2009 Share Posted December 4, 2009 Have you flushed out the intercooler? The difference between a clogged one and a clean one may amaze you. Cheers, John Quote Link to comment Share on other sites More sharing options...
Banjo Posted December 4, 2009 Author Share Posted December 4, 2009 Both mechanical, brand new lift pump from lr. Yes it does nearly stall if I rev it from idle. Flushing the intercooler today. Its really annoying me now as I can hardly get up hills! Banj Quote Link to comment Share on other sites More sharing options...
Banjo Posted December 4, 2009 Author Share Posted December 4, 2009 Have now flushed the intercooler out and checked everything its def not enough fuel, have checked the sender area pipes and drained the sedimentor jobber, do I have to take that off or is draining it enough? Any more ideas? Quote Link to comment Share on other sites More sharing options...
Banjo Posted December 4, 2009 Author Share Posted December 4, 2009 OK been to a derv specialist and he reckons some springs inside the pump can break? Gonna nip the pump off and have it apart. Are 200 and 300 pumps the same apart from the egr stuff? Quote Link to comment Share on other sites More sharing options...
Banjo Posted December 6, 2009 Author Share Posted December 6, 2009 All sorted got a pump off a 200tdi in the scrappers they are the same as a 300 but without the egr tps, goes a good un now, thanks for not helping me Quote Link to comment Share on other sites More sharing options...
BogMonster Posted December 6, 2009 Share Posted December 6, 2009 thanks for not helping me Perhaps nobody knew the definite answer (I have been around Tdi engines for 13 years and have never heard of springs in a pump breaking, nor have I ever tried to fit a 200 pump to a 300) but with a reply like that, more 'not help' is probably guaranteed Quote Link to comment Share on other sites More sharing options...
JohnL Posted December 6, 2009 Share Posted December 6, 2009 ... goes a good un now, Good to hear ...thanks for not helping me Uh... I hope you just forgot to add the smiley as a few here helped you. We may not have had the answer but, nevertheless, it was still freely given help. Quote Link to comment Share on other sites More sharing options...
