Look at the fuel lines see if there’s fuel , just in front of the drivers side rear tire, mine had rotted through the vapour line. Chugging and hard starting, low 50’s fuel pressure.
After replacing the fuel lines, back to full normal, starting, no chugging, no fuel odour.

It's DAMP with fuel at the connector. I didn't poke any further with fear of making things worse.
Oh boy- now to find fuel lines I guess?

So, I found a nylon replacement on Ebay?

or should I go back to steel from RockAuto, I'd have to buy the whole kit.

Any thoughts on the injectors after posting my fuel pressure readings? Or do you think this could be attributing to the P0172 code as well?

So, I got the fuel line replace/repaird midway up the car last night.
It runs better for sure. Startup is "better" but still chugged just a slight bit upon startup after sitting.
Is there a procedure to confirm the fuel pump is slowly dying? Starting to think I'm just "replacing" parts.
When running, it's at 60psi.

How long does it take for the fuel pressure to pump up? I noticed my fuel pump taking longer to pump to pressure when I turned the key to on , but not to start. It should take a second or two, I changed the fuel pump , then found the fuel line leak afterwards.
