I have a fuel pressure gauge on my sled, after i shut the sled off the fuel pressure drops. It never did it last year at all, but now it is. Its a 98 zr600 EFI. Its hard to start some mornings when its cold out, i end up jumping a battery to my fuel pump to get it building pressure. Other than that, while im running im at 36psi. Would this be my fuel pump back feeding? or my regulator is pooched? I blew my sled up today(not fuel related) and i would like to get this sorted out while shes all apart. Thanks for any help guys and gals.
