Good point. The fuel pump control circuits in any D-jet brains would
be the same. >>
Ok, I installed the t-3 "D" brain I have here, and now the pump runs, and I
hear the front relay energize. I guess that means the T-3 ECU is good, and my
T-4 wiring is good. : ) I guess this also means that the T-4 brain that I had
installed is bad. I seem remember reading on STF in the FI forum, that if the
D-jet brain gets wet, it can short out internally. This one might have had that
happen to it sometime in it's life. Oh well, at least I didn't have too much
money into the T-4 FI brain and wiring harness. :O Now I just need to get a 0
to 60 gauge so I can check the fuel pressure and set it if it needs to be set,
and then check the bleed down of the fuel system. It's getting closer to
running now. : ) Just have to wait on the new T-4 ECU, and then install it.
Thanks for the help.
