no start of key, if towed starts straight away. checked timeing, injector leak off,all ok at intake manifold theres a glow plug come injector poss a cold start device. these are not getting any power but plenty of fuel can any one shed any light on where the control module or relay is for these items.

On all ten I work on none of these are wired up.they are connected when they are,to the starter solonoid.My text book lists them as a CAV designed mark 1 or 3 thermostat.And states "gravity fed adaptor,heater coil "Thing actually ignites fuel!What i have had with these is on three of them is compression loss due to valve clearances which was a pain cause local dealer would only supply shims in packs of 5.Even less help was the range of sizes.Had to resort to removing valves and shortening stem length on a snaped belt rebuild,laborius.Anyway all three starting problems were solved.If your equiped I'd try a compression leakage test.on mine this showed comp loss of 15-20% on holding pressure,could'nt get a feeler gauge into several exhaust tappets.Not suggesting same as your's as i never tried tow starting them as it scares the crap out of me .but worth a look.good luck
