Renault Kangoo I 2004 diesel. No start! let's fix it! or can we?? 

One thing to check, there is a round red light on the dashboard, when you turn key to light dashboard, wait a bit and that light may start blinking faster. This means it doesnt recognize key radio sequence, immobilizer is on and will cut the fuel to the car. If it happens only sometimes, can be caused by coil next to ignition key, or the key circuit in the plastic part is weak. It is known that the keys circuit becomes weak after a few years. You have to take the key to a shop to clone your circuit, needs to read the code from old one. They also have some small bar, its a circuit in a chip, that can replace the entire old chip board in the key. Once cloned, your key should work, for a few years, anyway. For emergency, there is some sequence of buttons to press, that will bypass immobilizer, but works only once, you have to repeat when you start car again. It involves pressing central locking buttons in a certain sequence, you can google about kangoo immobilizer bypass. Even if you change ECU, it will still need pairing with key and still may not work if key radio is weak.

I had the same problem with my Kangoo 2005. After 2 weeks of trail and error it has now run perfect for over a year :D For me it was the connection to the EGR valve.

It’s nearly always the injectors on the kangoo, worked on a lot of them with this starting problem and 9 out of ten times it’s the injectors

This car is more practical for delivery services.

Where is the fuel replay located and how do I know the fuel relay

My old Renault Kangoo, has been sitting on the same place for 6 months, and now when I have my chance to restart it, it won't. There is sometimes a click . This sounds like the starter. Problem is, I cannot locate the starter on this low to the ground Renault kangoo. It is a 2002 1899cc diesel. Can anyone tell me where I might locate it after much patience and seeking it. Many thanks

You can solve the problem by using a 12 volt 74 amp battery.

How much ECU cost ?

Excellent. My kangoo has this EXACT problem. Camshaft & immob error code but everything checks out ok, but it will start only after 4 or 5 attempts. I will check the ECU contacts.

Pump in tank

I have exactly the same issue with the same van, same age and 235k mileage. It doesn't start but when I spray it with easy start it will drive all day until I stop and have to spray it again and it works! If you find a fix please let me know :)

Mine will start 10% of the time on its own and 90% of the time with easy start. Once it’s been running then it usually starts every time for the rest of the day unless it’s a long drive. If it’s a long drive and I stop to get fuel or food, it makes a strange knocking noise and doesn’t work until I leave it for 10 minutes and spray it so it will work again. Any ideas please?!?!
