If you don't hear the pump running, try giving it a couple love taps with a dead blow or rubber hammer. Prior to condemning the fuel pump though, you should do a pressure test.

I recall attending a Sportsmobile rendezvous in Kamas Utah and one of the challenges was to find your the diesel reset button.......they are activated if your involved in a collision and the shock shuts down the fuel system.
I have the 2003 SMB EB50 7.3 any one have a clue where it's located?

Test your fuel pressure. I know the 7.3s of this era have an issue with the cam position sensor. Not sure if your motor uses the same part. But the problems you described was just how mine were when my CPS went out.

By the passenger foot well behind the plastic on the right.

Just an fyi. The CC models have the switch above the brake pedal
Newer flex fuel Van's don't have one at all. The restrain control module signals the fuel pump driver module to shut off when there is a big impact.

Are there other "things" I should be aware of, failing due to age?
I recall the Army maintenance unites had a sign which read:

"Preventive maintenance Prevents Piss Poor Performance".

Along the line of preventive maintenance consider replacing the two high pressure oil lines that go to the fuel rails on the cylinder heads. The Injectors use very high oil pressure to open, when the line blows your left dead in the water and have a completely oil soaked underside of your van. Had it happen to me on my previous 7.3 van, luckily it went when the van was parked in front of my house, but the week before was out running around Death Valley with the family on a solo trip. Would not have been good if it went out then, got very lucky.

Thanks everyone. I'm leaning towards " its the fuel pump". When I turn the key to the on position 5 or 6 times I hear the fuel pump turn off and on. Then immediately turning the engine on it starts right up. I let it sit for awhile then come back and try to start it , it just cranks.

It could very well be the pump, but replacing it on hunch may not fix the problem. It's far less expensive to do some pin point testing as outlined in the factory manual. While the pump may be shutting down, there are other things that could cause it to not run. Starting with checking the fuel pressure is inexpensive and may or may not point to the pump. Logical trouble shooting rather than simply replacing parts can end up saving time and money. The procedures are outlined in detail in the factory manuals which are available on Ebay and Amazon. I never leave home without mine. My last 7.3 shut down due to a faulty injection pressure regulator. It would run then die. Best of luck
