I need some help figuring out what is happening here. I have a 1987 samurai with (supposedly) a 94 tracker engine. The 1.6L 8v. Last summer I went a bit too deep in a puddle and a bit of water got in to the engine and the ecu/ecm ended up under water and not working. So I had to rebuild the engine, that seemed to go smoothly. So I got a new ecm for a 94 tracker, and tried to start it, but it wouldn't work. Has compression, spark, and fuel only up to the injector. But the injector won't let fuel past it, and into the throttle body. I checked the injector and it's fine, and then figured out that it wasn't getting power from the ecu. So I checked the ecu and realized that the old one and the new one are different. Completely different. The old one is the one that used to work, but after running the serial number its telling me it's from the 89-90 tracker, and that it's incompatible with the 91-95. So either the engine is a 89-90, or I don't know. So I don't know what route to take. I'm thinking I should just buy the ECM for the 89-90 and see if it works, but don't want to waste more money on something that won't even work. Or maybe I could find somebody to rebuild it for me? The serial number for the old one that worked is 33920-60A32. I just need some opinions on what to do.. help me..
