Default Adjustable fuel regulator problems

I have a mini ram intake with the adjustable regulator with a fuel pressure guage on fuel rail. I change the adjustable regulator out for a new one when the new guage was showing false readings and would not adjust properly. After installing the new regulator, when trying to start the car the gauge would show 45lbs and drop down to zero. If turn the swuth off and back on again the pump will energize and the gauge will do the same thing again. The pump is working correctly when I hot wired the pump. I'm noticing that I dont have spark at the plugs when cranking. I change the module in the distributor as well but there is still no fire at the plugs. Thanks guys for any help you can give me.
