If I left the high pressure pump wired to a switch would it cause any problems?

I have it wired to the battery and a 15 amp fuse on the hot wire tied across a toggle switch in the cab right now.
I agree I would prefer it oem its cleaner.To get yourself out of a jamb... Absolutely.
Just don't consider this the solution.
It is indeed a 87. And that's what I have on mine I'll be soldiering the wires to the pump this weekend. Your not missing much just a bunch of trouble shooting and suggestions. Fortunately for the truck (and my sanity) all the people here helped me get it sorted out.So I didn't read the whole thread. I'm guessing you have the 87 in your avatar name. The frame rail pump connections right at the pump, under the rubber boot, have given me problems on every one that I've owned. Now as a matter of course I remove the stock crimped on connection and replace with a new female spade terminal on every pump of that era. Keep an eye on the 2 ends because one terminal is wider than the other. I'm not sure if mixing the 2 would damage the pump but why take a chance.
Well that would certainly cause low fuel pressure... glad you found the fault.
Sure seemed like a fuel issue to me.
But maybe the poor connection at the fuel pump was your vacuum leak. Stranger things have happened!
