1.7 TZD cold start problem
Hi, My TZD won't start on all four cylinders first thing in the morning. It starts but shakes around on 2 or 3 for a minute or 2 pushing out grey smoke all the while. If I use the heaters 3 times it will start on all 4 OK. Once it is running it is 100% OK. No smoke , no missing , no water loss, uses no oil. I have checked all the heaters and they all look the same , all heat up in the same time . This has only started since I changed tge head. Any Ideas?

By checking the heaters do you mean you have removed the glow plugs and watched them heat up with 12V applied? Your symptoms sound almost classic of one pot not firing up when cold - which the first port of call would be the heater plug and its connecting cable.
Someone really needs to do a nice post that we can use as a "sticky" for diesel starting problems - any takers? (Dave Burns where are you?)

Sounds like glowplugs to me, you can test them after removal by holding them with a jumplead and connecting (touching) the terminal post onto a battery,(the jumplead being connected to the other terminal) if they arent glowing/smoking in three seconds then theyre dead.

Sorry for not reading your first post carefully the cold start misfire might be air in the fuel or dirty injectors, if you have a fuel priming bulb (depends on year) try priming the fuel system before the cold start, a shot of injector cleaner may help too. I have had similar symptoms which have cured themselves.

You say this only started when the head was changed?
I had an identical issue with a 19 n/a some time ago that was always fine, then I had to change the head (gasket went), fitted a skimmed head and it started like a bag of s*!t when cold, but was fine when hot.
That turned out to be the valves not seating fully and allowing a touch of blow by which cured itslef once it had been running for a few seconds....
I take it the cold start on the pump is working properly and the timing is ok?
Cheers

Smokes lots, because enough's enough already!
