D21 starts with the injectors outside

Hello friends,

I have a 2001 Nissan D21 2.4 double cab single cab gasoline engine that won't start no matter what I do. When I remove the injectors and move them about 3 cm away from their position, it immediately starts when I put them back in. Two days ago, I had the injectors cleaned and the fuel filter and lambda sensor replaced. It was running perfectly, but now it's dead again. What should I do? Any help would be greatly appreciated.

Based on what you're saying about it flooding, what I would do is remove the injectors and send them to a test bench to see how they work. If they don't close properly, it's sending a constant flow of fuel, just to make sure they're working correctly.

I already sent the injectors to be cleaned and I imagine that when they clean them they should calibrate them too, but I'm going to have them checked anyway.

Another symptom I observed is that all four injectors work at the same time; I don't see the 1-3-4-2 sequence.

Hello friend, did you manage to solve the problem of your Nissan D21?
