Shifting issue

So many issues. No codes appear on scanner. Except DTC fault on dash a week ago. I have been working on car for 2 days now. 2002 Jaguar Xtype 3.0. It was running but would die if I didnt unhook the battery over night. Toke it advance auto parts confirmed it was the alternator, overcharging.
Had time so started 2 days ago on it. Changed altenator. In doing so. I acidently ripped wires from the plug thats connected (i believe its called) throttle position sensor. The plug is connected to Deson 198500 3300 sensor.
I tried rewiring with it back together from pics on internet best I could. Now did that cause more problems by wiring it improperly and trying it all kinds of differnt ways. I checked all the fuses one 10 amp was blown, not sure if that was old or new. Engine will start with starter fluid run for a second and die or just continue to crank. I hear the fuel pump kick on before start. I dont have a preasure guage, I tried the thing where you take off cap and insert a screw driver. And NO there was no fuel that comes spraying out. The original semi good Altenator is back on.
Agin it was running before I attempted all this I dont think its a clogged fuel pump or lines. Im attempting to locate the fuel kill switch? How can I find the correct way to rewire plug? Figure out if fuel is getting to engine? Any help would be so so appreciative. I so defeated.
