Cold start problem

[eno0708]

Hello every1...i have a 2006 corolla verso 2.2 diesel d-cat and only in the morning especially when its cold it have problem starting....sometimes it turns of and need 2-3 other times to start...but mostly it starts with 1 time....the problem is that the rpm needle for 10-20 seconds go up and down and then it stops at its normal position... ive checked the injectors and are ok...i know maybe are a lot of other reasons for this problem  but i want any opinion  from you!!...thank you!!

Can't help with the rpm needle issue, but with a diesel engine having difficulty starting from cold, my first action would be to check the glowplugs, rather than the injectors

Yes that might be also the problem ... Or all the spark plugs..thank you
