No power to fuel pump.

No power to fuel pump.
My 2001 truck lost power and quit while driving. My son and i towed it back home.
1) I have a pressure gauge. It is showing no psi when i cycle the ignition key. I checked the #30 fuse in the cabin (it looked good) and even replaced it, still no psi.
2) I removed the pump thinking it was bad. I tested it with direct power in a bucket of fuel. It pumped and worked great. 3) I connected a test light to the pump wires and cycled the ignition several times, no light-no power.
4) I have felt for the reset button on the passengers side . I can stick my finger in but feel no button . I apparently need guidance with the reset.
5) I will disconnect the bowl heater tomorrow (just to do it) and retest for power.
Suggestions of where to go from here?

I am supprised at the lack of responses, unusual for this FTE family.
Well 19 was/is blown. I had one spare new 20 amp fuse.
I cannot look and see an obvious difference between the good and bad.
I got my meter out and got nothing on the one from the box -blown- and a slight reading from the new fuse. Installed new fuse and test light lit up. Cycled several times and lit each time.
I re-installed the pump and the truck did start and idled but still no psi. I shut the engine off. I reattached test light-nothing. Retested new fuse-nothing-blown.
Removed pump from truck again. Powered it up in the bucket, held my finger over the outlet and i can stop it. It takes effort but i can stop the fuel flow with just one finger.
Should i be able to hold and stop the fuel flow with my finger? Is fuel pump bad because it is too weak? Weakness causing fuse to blow?

I had the same issue it was a 30amp maxi fuse under the hood that blew because of the fuel bowl heater. Same issue. No power at fuel pump but jumper wires from the battery made it go. Triple checked all my fuses and found a bad one. Solved my issue.
Before that I tried the reset switch. Couldn't feel much so I took out the plastic panel there and didn't see much more than when the panel was still installed if I remember correctly.

I agree with Joe. When your pump builds up to much resistance internally it will blow the fuse. Clay (in my sig) has an oem one for around $208 iirc. Dealer would be about double that.

It looks like i found the real problem. I also guess i invited the problem.
I did buy a new pump but the old one (Airtec E2236. Made in the USA.) did not cause my failure.
After the purchase, i decided to do one more run-through of the likely causes of no start/no run.
Years ago i added electric heaters to my fuel lines utilizing a relay. I powered the on wire to the fuel pumps power source. That wire got moved when it was being repaired last year (i overlooked it ) and it worked its way to an exhaust manifold which burned through the insulation and grounded out.
Maybe my finger is stronger than i thought.
I re-installed the old pump and with test light also connected i started the truck. The psi returned to 60 plus. Everything is operating back as usual. I let it run for about 10-15 minutes excellerating it a number of times.
Now, to keep the new pump as a back-up or return it? Decisions, decisions.
Thanks to those who responded.

Put on the new pump and keep the old one as a spare. That's what I did.
My reasoning is I may never have to change it.
