Fuel pump runs and kicks off after a few seconds before I try to start it

 

[faztbullet]

What is the fuel pressure?

 

[robert evans]

What is the fuel pressure?

I haven't checked it yet that's next on my list

 

[robert evans]

I don't know what fuel pressure should be it checks about 2 pounds

 

[faztbullet]

Should be 35+psi when fuel pump is running, if not pump or regulator is bad

I went to harbour freight purchased new pressure gauge presser is 35 on new one I noticed that the primer bulb has a leak in it could this possibly be my problem
