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.
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!
