Thread: Hard to start TDI 300 Disco

Gday, there was a similar thread last week or so, few people including me have the same problem. I have new injectors and glow plugs to no avail.

Cheers.

Battery? It is geting colder & batteries dont like this.

At start up, it will belch smoke its a 300Tdi

What he said, new battery= easy start, old battery= harder starts especially when its cold,
have just replaced mine again got 4 years out of the last one, but it too was doing what yours is doing.

the smoke on startup is typical disco 300tdi , thats how you know everything is working fine, fuel.injectors injector pump etc.

Have you ever cleaned the earth strap connections?

Had same problem, just replaced the battery.. no longer have the problem

Had the exact same problem so replaced my 550cca battery to a 750cca and no more probs in the morning. Got a yellow top optima battery which is great!!!

See, I don't understand this.

I have 1200cca to work with (i.e. 1 x 550 and 1 x 650cca). Batteries are less than two years old. SURELY that's enough grunt.

Yet, the old girl starts like a pig on cold mornings.

Cleaning terminals and earth straps before I shell out any hard earned I think.

Interesting thread(s).

Will advise.

I reckon its a combination of tappet clearance and pump timing as i dont have any problem starting mine with a 2 yo 670cca main battery, and although it should make no difference at all but since fitting a new alt it seems have had a power injection.
