right guys, did the diagnostics check and it came up with fault code 14 which is ignition signal, but i 18month ago i replaced the whole system (ht, sparks, dizzy rotor arm) as it started missing and this solved it but i never cleared the fault code so i cleared the system of codes tonight started it, tested the system, no faults, took it for a drive and it played up again so went home did another diagnostic test and its showing no faults still even though its still playing up so going to put my standard fuel pump back on tomorrow night as i never had any problems with that in, i only changed it preparing for the td04 conversion. so hope it is that then i can get in touch with dave a td and get a new 0ne sent out as its only 2month old and still in warrenty and hopefully be fixed for free, but the one thing its stil doing is the rev needle is sometimes all over the shop and sometimes says what the engine is actuly doing and i carnt see the fuel pump affecting this??? cheers for the help guys il send everyone a chocolate orange if it gets fixed!
