Mine did 55 psi with key on, 45 psi running. Very hard start, but did fine when warm. It did hold pressure. The low pressure would give a lean code bank 1 and 2. Replacing the pump this weekend. Great video. FFI, take off the brackets that hold the fuel lines in the frame rail. The very front has flex lines. This way you can lower the tank and get to the top of it way easier. Also, the tank can sit on the ground hooked up and test the pump.
@@KNKRNR I replaced the fuel pump today. Solid 55 PSI and fixed the issue. My friend owns a shop and said it should be between 55-60 PSI while running.
Should hold full fuel pressure minus 5-10 lbs max for 10 minutes so no less then 44 lbs key off @10 minutes. Sadly most aftermarket fuel pumps bleed back after 30 minutes. /K&K
It's a safety factory, liquid fuel is safer to work with then a tank full of vapor. It's not to bad to remove a tank with fuel in it but going back up is a different story. Other issue then you gotta store siphoned fuel in 5 gallon tanks. These new EPA fuel cans are just awful to work with. /K&K
Normally you would jump at the relay being its the load side of circuit and the direct path to the pump. You have to know which pin to jump or you could burn up the PCM. You should use a wiring diagram for that year and do pin point tests to find the issue if power is not getting to the fuel pump. /K&K
