New to the forum, I'm looking for an ecu for my 02 OZ rally. The ID# is mr578519. I've searched all over eBay and every other part distributers with no luck. I can't justify buying an ecu for a Grand when I bought the car for $1500 a few years back. The ecu is taking a dump and isn't getting spark to #2 and #3 cylinders. So I'm hoping maybe one of you fellow gear heads have one sittin on a shelf in your garage somewhere. Thanks -Tank

 

Anyone know if there's a way to possibly refurbish the ecu I have? I'm guessing its not as simple as spraying some dust-off in the pins.....

 

Auto or manual?

 

Manual 5 speed. Anyone know of an interchangeable ecu compatible with my application?

 

Its not the coil packs, not the wires, I have a feeling its either the ecu or a burned wire somewhere in the harness. Has anyone had this problem before?

 

Anyone?

 

Anyone know of another reason why I'm missing on two cylinders? A wiring diagram for the coils would be a huge help. I know I'm getting fuel. I've tested all the injectors. Im getting spark from two wires. But the other two are dead. I've tried switching the coils to see if it would follow the "bad" coil (if there was one) but it didn't. It stayed at the #2 and #3 cylinders. Any ideas? Thanks.
