Mech fuel pump, the scanner wont even power up. I took the harness off the PCM and with the key on or off I took a test light to all the pins and got nothing????????? Now what. I need to figure out why the PCM is not getting power. I cant go any farther until I find out what the fuse layout is. Theres no books anywhere! I even went to the dealership and asked them for a print out and they told me that the guys hand them in there books but I could not get it printed out. I hand to leave there before I got arrested! Is there any where I can go online? I cant believe I have to wait one week to order one. By the way to **** is stupid that they dont have the panel cover labeled or the fuse block numbered!

Go here and download the Owners manual for your truck.
It has both fuse panel diagrams.
I found one for a 1996, it should be the same because you have a mechanical fuel pump.
You might need to contact the maker of the bus portion of your van. You actually have
a van/chassis as far a Ford is concerned. Ford may have provided an up-fitters fuse panel
for the maker of the bus part.

Your 98 is electric or mech fuel system? (late changed)
Did you transfer all the wiring from the 98 to the 97? Your 98 is a splitshot motor and the 97 is a singleshot (4 gpr wires). The 2 extrawires are for the Gp monitor system. Your 98 should of had a shunt bar on the GPR.
First mission is to see why the WTS lamp is not on.
Get the meter out and test fuses, relays, fuse links as a starter.
Then move onto keyed power to PCM,IDM
The sign of no WTS lamp is a 12v control ckt out, bad ground or bad PCM.
Then you can move on to trying to start.
Fill the HPOP. It should start but will run like crap until you change the injectors or have a chip burned to run the singles.
Come on Rog Test yourself! Iam shure you can find what is up.

You are right they are split fire injectors. I got the thing to run but it is pretty choppy and alot of white smoke. Is there any reason to assume that it would be anything but the mismatched split fire electronics on the single fire injectors that would make it run like that? I was thinking that wouldn't I be able to just change the IDM to the 97 IDM?

Neal already covered this above:
It will run but to run properly the PCM has to match the injectors. I know a single shot PCM will run splits but not sure if a split shot PCM will run a single shot as in your case.
