As if my car problem wasn't as complicated and stupid enough, I now have
yet another random tidbit of information. On the front right hand side of
the engine, almost right below the distrubutor, there is what looks like a
ground strap from the engine block into the main wiring harness. I found
out today that if I disconnect everything EXCEPT that ground strap and the
EEC, then the 4.5 amp short is present, without either the TFI or the VSS
connected. If I disconnect that ground strap, and just leave the EEC, it
So I checked the continuity of all the wires in the EEC harness to that
grounding strap, and pin 59 was the only one with continuity at all, and it
was something like .3 ohms, which is a good sign. The 89 diagram from the
chiltons book shows that pin 59 gets spliced out to Fuel injectors 3, 5, and
6, and then gets spliced back into the three other injectors, a couple
sensors, and back into the relay module.
Anyway, the newest theory is this: Since the line goes from pin 59 of the
computer, out to three fuel injectors, then back into a line into the relay
module, which is unplugged, it's a good bet that somewhere between those
three fuel injectors is a pinched wire, touching the block, going to the
grounding strap, and creating the 0K Ohm short.
If anybody has any comments or flames regarding this, i'd certainly like to
hear them. I'm going to get out there probably this weekend and start
pulling off the intake and the the injectors.
