I thought about bringing an old thread from a couple of months ago back to life, but too many of the details have changed since then. So, here we have part II. Tommorow morning, I will be picking up a 5.9 from a 1994, complete with harness, PCM and all accessories. The EFI portion of it, and eventually the whole engine will be going into my '78 Power Wagon. I currently have a 5.2 Magnum that is carb'd. I have a few questions, so hang with me...
1) Will the 5.9 PCM supply the correct pulse width to the injectors to make my 5.2 run smoothly, or do I need a 5.2 PCM?
2) My PCM is from an automatic trans. truck. I have a manual.
A- Will the computer run the engine even though it doesnt "see" the transmission or
B- Can my PCM be re-flashed to delete the auto trans configuration?
3) I want to keep my stock gas tank as-is. Is there an inexpensive, inline fuel pump that self regulates to appx 49 psi? (also double checking to see if that is the correct PSI I should be running.)
4) Has anyone built this type of system before and if so, any tips?
5) I understand that the pre 95's require a return fuel line? Double checking that as well.
6) I have detailed diagrams and schematics from a '95. Is that all the same gear as the '94? Same info apply?
Thanks in advance guys, Scooter.
