starting problems

Hello, I have the next problem, I have a megane 1.4-16v and sometimes the start fails, it does not always do it only and the battery is fine, what can it be?

You do not explain what kind of failure it produces, as if I had no strength, it does nothing, and after several attempts it starts without problems ,,,, you should specify a little more interest Pelated cable, excess fat in the boots of the starter engine and arrives enough current, and if here everything normal ,,,, disassemble and change brushes, check the induced and the rotor, review the rotor that part where the copper material has some crack quotes that are filled with gray matter, or black

hahaha But it is what usually fails more often, unless they are things from another planet hahaha

The problem can be in the same starter engine or in the starting relay (located just above the starter engine and also called "automatic")

either because the dirt in the starter of the starter engine prevents the current from circulating correctly causing failures, of the type spin the key and does absolutely nothing or does some click but does not turn the engine.

Well because you are running out of brooms in the starter engine in which case the same would happen to you.

or because it is the starting relay itself that does not close the electrical contacts that feed the starter engine (the gordote cables behind, one comes from the battery and the other is very short and goes to the starter engine)

in any case it is up to you to disassemble it, for it and very important:

first the battery dough

after having removed the start of the car, clean it well and disassemble it. What's wrong with him.

Another option you have is to go with the dead start to a spare parts house and request a repaired and reviewed starter engine, in which case they will pick you yours and previous payment will change it for another and with guarantee.

Another cheaper but more risky option is to go to scrapping and bring you a starter engine, there are scrapping in which the pieces have three months of guarantee but not all.

I hope I have helped you.
PD looks at the post "or you help me or I stay without a car" of Michelker because exactly the same thing happened to you but in a 92 Ibiza.

Thank you very much I will do so.

Well -known is your renault's problem, it is a preschool failure.

I would quickly tell you that you replace the detonation sensor that is just above the CJA of changes and all fixed, but beyond this, I would also tell you that it is a problem already solved by Renault itself and the solution is not the collector that mentions, if not its plug.

Do not give so many laps to your Arranke engine or masses that there is no.

Do a real workshop and tell me.

It is an ultra cheap repair, it is not a repair is a substitution.
