Where is the cylinode located? I was told that I had to replace the fuel pump in the back of the truck when instead this happened due to a problem located in the front of the truck (front engine - driver side). There was a rusty stain on the driveway that corroded the color away.

Try replacing the cold starting valve. Also, it would save the battery and starter by cranking a couple of turns then stop. Wait a few seconds giving the fuel time to run into the engine and crank again. It should fire right up. Count to ten.

This is if it is an internal filter, if it is not you still have to pull the whole bottom of the back seat out and look for the inspection plate.

i just had to replace my fuel pump. it was doing the same thing. my mechanic told me to tap on the pump located in the trunk for the 97 j30 while someone cranks. Before it went completely out this would work to start it.
Let me explain real quick the fuel pump circuit, when you crank to start that is a straight circuit to the pump via a fuse in most cases, when the engine starts and you release the key the fuel pump relay is energized and keeps the fuel pump running, it sounds like the fuel pump run relay may be the problem with your car, replace it or bypass it to test, if you don't understand how a bosch relay is wired don't jump it yourself, you can burn up the wiring.
