Thanks for the fast reply Moparman. Garage just called he unplugged the edge juice last night but the pump wire is still attached and fired instant this am. So the edge must be defective. He put it outside its -15C today and hes going to try it again tonight at 5. i did notice one time the edge screen was black said communication error or something when i turned key on during the cranking.

Hi All I have searched high and low and didnt seem to find anyone with similar issue. Just bought a 2002 6 speed with an edge juice and fass ddrp lift pump rebuilt VP at some point. The issue is sitting overnight it looses prime between vp and injectors. Parked nose downhill so front bumper was a good 2 feet lower than rear. Same thing only low pressure fuel to #4. After muchhhh cranking dribbles at 1 and 3. It will eventually fire up like nothing happened no smoke. pulls hard on road absolutely no drive ability issues fp 13 at cruise on level 3 and 17-18psi idle. Tried unplugging lift pump to test for bad diaphragm and it still didn't start. Sits for 2-3 hours and insta fire. Its at the shop now and they tried to start it after sitting overnight and same thing no high pressure at injectors. Fuel at vp inlet no air. They hotwired the vp and instant high pressure fuel at injectors. Plugged harness back into vp and boom insta start. They checked the pin thats not supposed to have any power only after the key goes off and all was fine. No codes either. Ecm issue ? Is it possible sticky rotor in pump and that the power from battery to the vp is stronger then what ecm sends ? Thanks

I tested mine today with the Ac 20V setting. Came out 0.01
