Hey guys my truck turns on good and idles good but right when I give it gas it starts stumbling and sputtering and has turned off on me. Changed allot of sensors and still nothing. Once truck warms up it would run better even on take off. But now going around 45 and giving it gas its sputtering. Didn't do that before would only do that on take offs. If i turn key to on position to build up pressure on fuel rail and press fuel valve it only drips a little bit of gas. Checked fuel pressure and when i turn key forward fuel jumps to 52 psi and then falls to 0 psi is about 8 seconds. Running idle the psi is at 45 psi. Weak fuel pump? Any ideas?
