Fuel issue?

[Ultimatefit23]

Im actually messing with it now. I haven't started it for about 3 days, so naturally it fired right up on the first crank fuel pressure was at about 52 maybe 53-54. Let it run 15 mins. When i turned it off psi went up to 60. 3 mins later it was at 40, 7 mins later 30. Im still watching it now. Will let you know.

So you changed the fp regulator on yours?

12:31 its at 20psi. Been there for 3mins, looking to be holding there.

Alright, you are onto it now. Does that motor have the "spider"?

Yes it does.

Boom. Good question.

Yes it does.

Well, I don't know anything about the "spider" but I would want to see if any of the injectors are leaking, if the fuel pressure regulator is leaking and if neither of them are and there are no leaks, then the fuel pump is bleeding down.

Let's wait for the guys who own these to show up and tell you how to best inspect the spider.

Anyone with the spider injector system? Im having problems as mentioned above. Would love to get your input for my truck.

Also have a new issue. Yukon wont go past 110 degrees at running temp. Let it run for about 30 mins. Same temp, it doesn't move. This just started. Wirked perfectly before. I removed thermostat to see if that'd help. No dice.

It sounds like the gauge temperature sender is not connected. I'm thinking the gauge sensor is on the driver side head and the computer sensor is on the intake near the thermostat.
