1991 3.0 5 speed Fuel issue

[M2116x6]

A few days ago I stalled at idle at a traffic light. Didn't think too much of it until it happened again later that day. Progressively got worse. On the weekend I changed the fuel filter. Minimal dirt found in it as it was only 2-3 years old. Now, it takes 4-6 tries to start it. After each key turn it will fire for two seconds and then die. On the 4th to 6th try it will stay running. The fuel pressure regulator has no fuel in the vacuum line. IAC valve had minimal carbon before I cleaned it. Would this be a fuel pump issue? I've replaced two other pumps on this truck in the past but each of those just flat out died. Have never seen these symptoms.

It does sound like the fuel pump is on it’s way out. There have been a few times others on here experienced similar issues.

Before you spend the money, make sure power and the wires are good. It could be as simple as a fuse with some brown stuff on the prongs. The last part is what killed my fuel pump but it was a straight up sudden die.
