JEEP Cherokee Classisc begins but does not turn on

Before the purchase I had to try everything now you said that you changed the ECU SENSOR OF SUSPERAÑAL BUJIA but you have not tried the distributor and the coil remembers that the distributor carries a captor to me it happened to me with an equal one that is mine and it was the captor to final

I have very good information about it, I also change an ECU and I couldn't start a Cherokee Limited, but that was 8 cylinders, what model is yours ???

But to begin, check the fuse "number 12 of 10 amperes" inside the board compartment, not in the engine compartment, "Eye" the 12 -fuse is not marked on the lid (you have not registered to be inscribed to be used) but this is a feed fuse (I do not remember if it is a revealing or direct to the ECU), to access it, you must remove a couple of fuses of 10 amp that come in a fuse. kind of yellow insurance. I explain myself ????

That fuse burns and for more that you are going the troca will never turn on, and for more Ecu's that installs it will never ignite, I have a diagram that I can facilitate, but to start checks that fuse and comment.

Good compa, well, this is quite sensillo. First look if the check Engine light lights on the instrument board of your vehicle, if not, replace the ECM fuse. Once you have turned this light, turn on when you give the contact you will follow the following steps to scan the computer and this will tell you where the problem is. As a clarification, you must start a couple of minutes without disconnecting the vehicle's battery so that the computer stores the DTC of the failure. Here I attach how it is done, it's quite simple, luck !!!!
