Renault Kangoo rapid 1.5 dci Start problems, first starter, then …

Hello. My name is Michi. I’ve already read opener here. But now I have a problem myself. My kangoo bj. 2004 1.5 dci. Has start problem. It takes place as follows. First my starter was defective. I then replaced it. Then it was great again. Then the glow control in the cockpit started to light up and the start behavior became bad. I then changed the glow candles. The bad start behavior remained. I tested the removed glow candles and the newly installed. A ll glow. So that wasn’t it. Now it’s as follows. The car only starts after a long 5-10 seconds organ. I mean that it starts better when I pump the accelerator a few times before like with a carburetor engine. (What can actually bring nothing). This morning I wanted to work and he cared and didn’t jump on. He orgs without a load as if he had no fuel. After work I tried it again. The same thing. Long organ don’t jump on. Then I have to ch pressed the pumpball 5-10x and it jumped on. The immobilizer’s control light is permanent. What is rightg!? I also tried both keys. Does anyone have one? Thanks for all the information.
