blown up part in 1995 geo tracker computer

The symptom was originally a poor running 1995 tracker 1600cc 16 valve engine. The symptom was tracked to #3 fuel injecter not operating. The injecter was tested and found to be OK. I was able to track back up the
wiring back up to a blown power IC of some sort in the computer module. ( smoke got let out!) The device looks like a transistor or FET and has the number D2422 on it. Does anyone have a generic part number or device description for a replacement? It appears to be the only device damaged that I have been able to find in the module.
Thanks

Check with Motorola and see if they can cross reference the driver, i had a similar problem with a Isuzu but it turned out to be a open in the injector harness. -- George S.

Thanks, I went electronic cross references manuals and found somewhat simular number that eventually translated to a radio shack TIP3055 NPN transistor. Its rated for 90 watts so I figured what the hey, installed it and it seems to be working, at least at in town speeds. I dont expect it to last forever. Like you, I also found a severe problem in the wiring harness, but I was able to temporarly rewire and rebuild that too. I believe that this happened when the young ones left the headlight on, then had to get a jump to get it going. I suspect thats when the computer got damaged. Next thing they know, its running real poor, the a backfire blew out the EGR valves and directed hot exhaust toward the harness. That kind of melted the rear half of the harness. It was an expensive lesson for them to learn. I still picture a trip to the boneyard to get a good set of spare parts such as a wiring harness, computer etc before I consider this vehicle fixed.
Thanks for your suggestion!
