Why does the fuel pump run for 20seconds with the key in the run position before you try to start the engine. I just replaced the fuel filter and thats when I noticed how long the fuel pump was running. The truck has 163000 miles runs good and starts goods I just want to know if you think it is a fuel pressure regulator is going bad?
have the same problem?
