90 GT help

So I bought my car last year drove it straight home and started a upper engine build. Here is the engine work that I have done. Trick flow twisted wedge 170cc heads, comp cams roller lifters, trick flow push rods, PRW stainless steel 1.7 roller rockers, APR head studs and bolts, comp cam stage 3 Xtreme Energy XE270HR camshaft, comp cam double roller timing chain, BBK 76mm mass air meter, BBK adjustable fuel pressure regulator, BBK 190 lph fuel pump, ford racing 24lb fuel injectors, Accufab 70mm polished throttle body with polished EGR spacer, Elderbrock 5.0 lower and upper intakes, BBK shorty headers, hooker mufflers. I got it done right before winter and only drove it maybe 50 miles. It sat all winter and now its time to get it back on the road. I drove it the other day and had several issues. I turned wiper on and they move slightly then stopped so I turned the wiper switch off. A little further down the road they moved all the way to up position and stopped then finally went back to park position a few miles down the road. Cruise control would not work. Temperature gauge would not work and the power windows were really slow. All of which worked great before I did engine work. Temp gauge worked through out the cam break in process too but not now. I'm thinking maybe its a grounding issue. Any suggestions?
