My 98 K3500 truck has not been starting that great lately after sitting for awhile. Today I hooked a fuel pressure gauge up to the port to see what kind of pressure it had after sitting for a couple of days. It had about 5 psi.
I turned on the key and let the pump prime to see high it would get. It went up to 58 psi and then started dropping slowly. About two hours later we are at 45 psi. I know that these engines have issues with injectors as they get older so I'm assuming that either some of them are leaking or that the FPR is.
I know you have to take off the upper intake to get to them. Has anyone here done this repair before and is there any tricks or procedures to make it easier? I understand that the EGR valve tube can be very difficult to get undone if it comes undone at all. I've been spraying it down occasionally for the past two hours in hopes that it will eventually come apart.
I've watched a couple of YT videos and they make it seem like a not very fun job so I'm not sure I want to tackle it or not. Thanks.
