Well, as the cam uses a woodruff key you can check if 180 out by looking at the crankshaft marking on the bottom pulley/block and the arrow on the cam pulley (think it points straight up for standard timing IIRC). Ign modules can fail without warning and are quite cheap to replace so may be a good starting point. 1342 anti clockwise firing order, make sure rotor arm points to number 1 when engine is at TDC to verify cam in right position. Do you have all the induction pipework on? Without it the flap in th emetering head will not be lifted therefore not allowing pressure/flow to the injectors. A compression test might be wise to validate everything is spot on as expected.

BTW, as an ex owner of 5 Mk3 3i's I think your project is the best one I have ever seen. It is an absolute credit to you and I admire the way you have stuck to keeping it original. Not that there's owt wrong with modding of course. Hats off to you mate - hope you enjoy it

thanks pal yeah I wanted the car to be totally standard no mods has all the original ford leads n water pipework with ford logo etc...


regarding the timing, the rotor does point to 1 come to think of it as checked this yesterday so that would be correct on the cam wouldnt it ?... wonder if it is the flap in the metering head not lifting ? all t he vac pipes etc are on also... hmmmm ..

a little update - the engine as fired and ran - abeit for a few seconds each time only.! ive stripped cleaned all contact points and rebuilt the dizzy today, refitted and tested for sparks on one of the leads on the head and it wanted to fire up first turn , after i removed new fuel pump relay so to clear overfuelling in engine , quickly and optmistically i replaced said relay and it was back as before just turning over - no hint of a splutter. remove relay and after a few cranks the engine wants to start up after the fuel starts to disperse.... finally does runs for 5 - 10 secs then dies, like it runs on fuel in the lines but wont with a pump relay in the loom. It also dies straight away when its running and push relay into pins.... ?!now bearing in mind that ive never tried to start it without a relay in as i also replaced the pump as wasnt getting fuel to engine , so maybe the dizzy thing has nothing to do with it ... as I had a good blue spark before.... so what could be the cause of this - too much fuel into engine - too much pressure ? bearing in mind ive not touched the co mixture screws at all ? any ideas that i can try ? also can someone confirm that it is indeed a pink replay that the mk3 xr3i uses as thats what was in it and what I bought to replace it....thanks
