Issue is with my 94 B4000 truck, 4.0 ohv, 5speed.
When I turn the key to start it, it will crank and crank and finally barely start running weakly until I bump the pedal to give it a little gas, then it roars to full running condition. Is this fuel pump, or something else?
When I’m driving, it drives relatively okay under a little throttle foot, but if I give it more throttle to accelerate or get up a slight hill, it will have hesitation, like no power for a split second, every couple seconds.
Overall, it seems to me like it doesn’t get enough gas, both when starting and when hesitating on the road.
I did replace the fuel filter.
Do fuel pumps get weak? I thought they either ran 100% or they didn’t run at all. Is this a sign of a slowly failing pump?
Or, possibly a vacuum issue? I do have a few of the smallest vacuum lines broken.
Trying to figure out which direction to look towards.
