96 Chevy K3500 with the 5.7l It has about 215K miles. I am trying to diagnose a fuel pressure issue. My truck first started to run rough like it had a miss. Check engine light came on. I had codes for both banks being lean. I cleaned the MAF sensor with no change. I checked for vacuum leaks. I hooked up a scan tool and checked the LTFT for both banks. They are both at 25%. I hooked up a fuel pressure gauge to the rail test port. Key on engine off it is around 45. As soon as the pump shuts off it almost instantly drops to 0. I am trying to figure out if I have a bad check valve in my fuel pump or if my FPR is bad. Before this all started, I noticed a loss in power. It could barely get a trailer up the slightest incline. I was trying to see if I could find out the difference in the speed of fuel pressure dropping when the check valve in the pump is bad and when the FPR is bad, to try and isolate the issue. -
I just recently purchased an 82 s15 gypsy edition roller and it was setup for a 327. I want to put a 1996 350 vortec or a 2003 5.3 in it and a t5. I’m having a hard time trying to find a t5 out of a 90s s10 but i can easily find t5s out of 90s mustangs. I was wondering what would it take to use a mustang trans in this truck. Any other tips and tricks are greatly appreciated as well. -
So I did the mpfi upgrade. Finally got the upper intake back on and go to start putting the studs down and torque them. But I got a new phone lost the photos I took of where each stud came from and brackets. I have maybe 3 give or take studs that are shorter then the other and I’m not sure if it matters where any of the studs go back in or not. I also have two brackets that I have no clue where they go and can’t find anything about it.

I've got a 96 yukon slt. It's got a 5.7 LG SGI vortec engine. Bearings ate into the crank and I need to know what's the best replacement to go with. I also want to put a bigger cam on it.
