1997 Ford F53 V8 460 Crank No Start
Help. She cranks but will not start. Battery is good, terminals replaced, inertia switch is not activated, I hear a click from the relay, swapped relays anyway with no joy, performed fuel pressure test with cheap Harbor Freight gage and got zero pressure. As I was about to start looking at the fuel pump, I started probing all fuzes in the distribution box with a test light. No power to fuse 11 (Starter relay coil) not even with key in start. The 30amp fuze is good but no power is supplied to the fuze. Now I'm scratching my head.

If it cranks fuse #11 and power to it is OK.
Sounds like a bad fuel pump.

It does. I will first try a fuel filter and I still have no pressure, swap pumps.

My 93 did the same. dropped the tank changes pump but before replacing tank tested the new pump, would not run. Checked power in harness all was good. Being an electrician started tracing continuity from pump back. Found the terminal on top of the tank was bad and not sending voltage thru to pump connection in tank. To keep from hunting down a new 3 pipe plate I drilled the plate and inserted a plastic covered crimp sleeve in the hole and made the connections then sealed the sleeve with gas resistant silicone on both sides. So far so good.

I was hoping it wasn’t the pump. I replaced the fuel filter and tested the inertia switch. Switch wasn’t functioning at its beat so I’m going to replace it. I don’t want to drop the tank with 60 gallons so I’ll have it towed to a repair place. I really just wanted to isolate it to the fuel pump. There’s no fuel pressure and I had my wife turn the key while listening at the fuel tank, no sound. Just waiting on my income tax to get her to a shop.

Before puling tank, check under hood fuse box. If horn works, switch horn and fuel pump relays. This fixed my fuel problem. Eddie Elk.

To drop tank containing fuel, Go on Youtube. Buy 2 heavy crank straps, put around fuel tank and frame braces, unbolt and slowly lower tank. Guy did it on Youtube. Eddie Elk.

I try and ignore Youtube howtos, too many talking heads with zero qualifications. Just changed my pump. Half full 70 gallon tank. I put a piece of plywood down and threw my motorcycle jack under it. Let down and jacked back up, easy peasy. I don't think I'd like using load straps. Cheaper though I expect. Different strokes...
My jack I already had as a father's day present. It came from WalMart but it's basically like this one. https://www.harborfreight.com/1500-l...BoCODQQAvD_BwE
I'm not big on loaning out tools but if I knew a neighbor was faced with such a job, I'd have my jack right over to them.

Thanks, I checked the relays and distribution box fuses but will double check. I ordered a new inertia switch to see if it’s that. I want to read voltage at the tank. If that doesn’t work. Replace fuel pump.

Looking at that jack. Makes the job seem like I can definitely get it done. My next concern is rusty bolts. Maybe I’ll spray with WD40.

WD 40 is not a rust penetrant. Get a good spray penetrant instead.

The last few years I've been using PB Blaster. It stinks but seems to have some actual penetrating value. It's paraffin based and mechanics have been using paraffin for such for well over a hundred years. so there's that. I find that if it helps, it does best if left overnight. I've tried about every other penetrant out there and found them useless. PB at least seems to help sometimes.
