Hey all, three things.

1. This is my first post. Nice to meet you all
2. I'm super new to vehicle repair in general. Picked this up as a new hobby because the winter is killing me.
3. I'm hoping you might be able to help me out with a fuel problem I'm having.

Problem:
- 2007 3.0 has trouble starting. Usually takes two or three tries to get it going. Discovered that priming the fuel line helped.
- Cylinder 4 misfired. Engine light came on. Cleared it and it hasn't happened since.

Hooked up a fuel pressure gauge. First turn to the run position outputs almost no pressure. Turning it 4-5 times gets the pressure up to about 10psi. At this point it turns over and we're good to go. Once running, the pressure sits consistently around 65psi. When I kill the engine, there is a rapid pressure drop. Back to 0 in seconds and then we have trouble starting again.

Hoping for a little help to get me on my way.

Thanks!
