Well friend Ivan CD22, we could have started there. As it is a Crysler, or Dodge, in this brand of vehicles you have to know applied science in them. I hope not to give you the can, but this insurance information will serve other automotive technicians. Since electronics were applied to the Dodge or Crysler car, the engineers determined that the 12 volts food sources involved in the operation of the engine will be controlled from a central unit. They determined that they will have a source of power and a source of control. When the vehicle is made, this source supplies 12 volts food to all motor control peripherals, ignition and injection system. Each separate output. This is how it was created. Then at the beginning of this, they came with a source of power on a card, and a source of control in another, but very much from another. Later, they joined them in a single box, which on the one hand had the power unit and on the other side of control. Later he continued to evolve, and integrated into a great targeta, and so it is until these days. That is, within the ECU is the source that supplies the food of 12 volts of the coil, and the Automatic Schut Down, feeds the injectors, so that anyway depends 100% on the ECU. As a sign, you can see mainly if you have check Engine on the panel. If it is not, unfortunately the unit is not acting, which could not be fuse by fuse or cut cables, which is little possible, or that the stabilized source of the computer does not work, beaming the entire control system below. The solution is to repair ECU, which someone should do in the matter, since you have to disarm the unity that has a sticky gel, which makes disarmament difficult, and long in time.
I, the first time I repaired a Crysler, did it with a Stratus, 2.4 Cyl engine., And it was a childbirth disassembled ECU, and repair it. It had an oscillator transistor of the power source that regulates the internal food and cutting voltage. I changed the mosfet and a matter arranged, but within a few days the ECU of the transmission stopped working, and re -disassembled the second ECU, which is in front of the transmission, next to the injection. But well, after that, with my partner we became experts in recovering Crysler in my region, and today many reach us with bad computers, and they are a common failure in these cars, which in the US the units are low cost but in Chile they reach the price of gold, and makes them recover them is a good business.
If you were here, I would offer you to repair it, but I can only give you guidelines for you to do it.
Finally, and as a recommendation, change spark plugs in time, change spark plug wires, distributor and distributor rotor tapas, in the models they have, it is vital to maintain electronic units working in good condition. Many eccus, ignition modules, coils and captors are saved by these small changes, since the sparks that do not reach the spark plugs, are returned to their places of origin, producing a counter-electromotríz force, which makes electronics break, or passive elements such as ignition coils.
Anyway, the manual is here in the Crysler archive, from there I lowered it, and I am waiting for some comment about how it went, or willing to answer any questions, that my experience can contribute.
Greetings and Suerde ... Valdiviano, from Chile.
