Dave,
What wiring diagram are you using?

The headlight relay may be bad. Suggest you start a new thread on the headlights, if they are still failing. (You do have the ignition on, right?)

"and a spark later and the pump started"
You mean there was a spark at the jumper that wasn't there before?

"also can't get intank pump running just the main"
You mean with the 4-6 jumper? Or when running? Or both?

"Also i have no power to the #5 fuse"
On your car (they vary by year and world market) #5 isn't used. Neither is #6 although its input side is powered (6-10 always hot, remember?)

Power path to tank pump is:
Battery=>25A fuse=>Fuel relay 30(in)=>Fuel relay 87-2(out)=>4-pin plug under glovebox**=>Fuse#4 left(input)=>thru fuse=>Black wire at 2-pin plug feeding pump.

** This plug also carried Main pump voltage

"Could my problem be the ignition switch or the computer?'
Anything is possible. The switch maybe, FI computer, hardly likely.
