check yer ground... there are some threads in the 911 tech section that cover this pretty well and is what I used for reference when I did mine. however, a quick test is to put power to the gauge, walk around to the engine and pull the wire off the top of the pressure sender. ground that to the block (I used a short piece of 12 gauge copper I had laying around to make it easy). if your wire is intact all the way to the gauge, the needle should drop to zero. really hard to see if you're doing it alone, but in a quiet garage, I could hear the needle drop (grounded) or peg (open loop/non-grounded). if there is no change, there's most likely a break in your sender wire and the sender is still good. pray it's your sender and not the wire (unless the break can be seen). let us know how it turns out
