Some sort of moisture from sitting around I guess or the last owner had water in the fuel
That would be the fuel going off and forming varnish. Not much to do with moisture.
Average 91 fuel goes off in few weeks to few months. Then becomes varnish not long after that. I had it happen to a ford that ran on gas, all the normal fuel system was full varnish. All 6 injectors were totally stuck and unusable.

its a stocker from a wreckers ,, so who knows .. it fires using start bastared i dont have o2 sensor connected as i need a 2 wire one but should still start added a in line fuel reg i had laying arround have 60 psi fuel pressure .. have a log here doesnt mean a lot to me but will load for you to look at if i work out how to
could bew worth pulling the plugs all off, wind it over a few times, then remove the spark plugs, see if they are all wet or not ... might give you an idea as to if an injector isn't firing.
No matter what the question is, the answer is always more horsepower!

Good to see! Im not sure what you have been doing with your tune but I believe that the VP engine takes quite a different spark mark compared the S1, so thats worth considering.
