i was checking checking the resistance on my fuel pump the other day and it read around 1.5 ohms and in the FSM it says it should be 0.7ohms. is that a sign that it could be bad? lately i think my car has been running lean since i saw white deposits on my spark plugs and on hot days (around 100 degrees) the car struggles to stay on when left off for a while after a 30 min drive as if the car wasnt getting gas. now if the fuel pump is bad i was considering getting wahlbro 255lph fuel pump. but since its a higher pressure fuel pump will the stock fuel pressure regulator be able to handle 255 lph? i would appreciate any help.

when you touch your pos. and neg. probes together what resistance reading do you get?
