My 2000 5.3 Tahoe has started to have a random long cranking almost wanting it to not start problem. It started happening a week or two ago. At first it was maybe once every 10 starts then got to be a little more frequent but then it will be ok for a little while. One of my buddies suggested EGR but then after hearing it he said probably not. I figured it was with the fuel and another buddy agreed with me. Possible fuel filter and or maybe shortly needing the pump (and if it is he already knows he is gonna be helping with it.) I've tried looking for the specs on the fuel pressure and have found no real good help. Anybody know what the specs are for the fuel pressure? It started to bug me tonight because I have so much going on right now with the house and all that I put the gauge on and took some readings at 11:45 at night. Off course as we all might know, with me looking at it with a gauge it ran fine and had no problems any of the 20 some times I started it.
The readings I got
Key on Engine off ~ 50 psi
Cranking ~ 56 psi
Running ~ 48 psi
Truck off after running ~ 45 psi
