Jimny won’t start.

Moin people. I’m back with a new problem. My Jimny FJ 1.5 Diesel doesn’t start any more. He always has the problem that when I was already driving he doesn’t start the first attempt. Mostly only on the second attempt, but sometimes it also needs three. Then suddenly he didn’t want to be in cold condition. I noticed that the lamp of the pre-glow system doesn’t even light up. But at some point then already and then he ran. So on the speedometer left from bottom to top the oil pressure lamp, a red engine control, a yellow engine control and above the pre-glow spiral. I noticed that only the oil pressure lamp is shining and the other three are not. Nevertheless, started, but does not start. Had this four, five times until now. If I make the ignition on and off several times, all the lamps are shining and it starts. Now after easy 20 attempts the two motor lamps and the pre-glow spiral still glow nic can anyone tell me what’s wrong with it? I’ve already tried the spare key. Does he have an immobilizer?
