So, having put my new transmission in, the car is now blowing MFI (MPI / EFI) fuses non-stop. So, one fuse could have been a fluke but 3 is a problem.
I'm actually leaving town tomorrow for 10 days so I'll be hit-and-miss checking this and I won't be able to do anything hands-on until after I get back but I thought I'd go ahead and throw this up to get peoples' creative juices flowing.
Clearly there's something shorted in the MPI circuit but I don't really know what's on that circuit or how it all ties together. I'm hoping we can generate a list of what pulls power from that fuse and any dependencies between those components. I know that the ECU, MFI relay, ISC, and possibly something alternator related are all pulling power through the MFI fuse. What I don't know is what talks to what and who gets power from where... If you have any insight please post up.
Thanks,
-Roger
