Ford RangerMore than two decades ago, the Ford Ranger debuted as an answer to various compact pickup trucks being made available by Japanese automakers. The Ranger was cleanly styled and offered with a choice of a 6-foot or 7-foot bed. Ford boasted that the Ranger had more interior room than the best-selling imports and that 4-by-8-foot construction material could be carried in the bed.
My manual says my working fuel pressure should be 35-45 PSI.
My fuel guage reads 31-32 PSI when it is running. Is that enough pressure? When I try to start the truck the fuel pump does not stop running. When the truck was running right, you could hear the fuel pump come on then turn off after a couple of seconds. Now it does not turn off. Is their something in the computer that tells the fuel pump relay to turn off when you first start the vehicle, or is there something else that controls when the fuel pump should shut off?? Thanks!
Yes the fuel pump should always be on when the engine is running, but when it's first started you usually hear the fuel pump run for a second then it stops. I went ahead and changed the fuel filter and found a little water and trash in the filter. I removed the fuel tank, cleaned it and installed a new fuel pump. Fuel pressure is over 30 PSI and it still has a hard timestarting. What stops the fuel pump from running when you first crank the engine? I noticed when I turn the key on and the fuel pump does not stop running, the truck has a heck of a time starting. As soon as the pump stops when the key is on, the truck starts right away. The check engine light does not come. So it is not putting out any codes. Suggestions? Thanks!
