I'm going to looking at a 91 F350 that's not getting fuel to the motor.

Seller says he replaced the hi/lo pressure fuel pump and glow plugs. He says it cranks but won't run.

First thing I thought was fuel filter and pick up tubes in the tanks.

Any other suggestions?

I'm going to look at it after work. He said it cranks but won't start and stopped putting money into it after the fuel pump.

I might get a can of silicone and see if she'll run spraying that in the intake.

I'll need an automatic for about a year after shoulder surgery then I can get back in the 5sp

I'd lay off the ether if you can. These engines are not that hard to get started. As long as you are getting fuel to the injectors, enough voltage on the batteries, and you have moderate compression, it should run.

Using ether sparingly is always a good idea with these engines. Also make sure to disconnect the glows when you use it.
Having said that, if your glowplugs aren’t working, or if there’s air in fuel lines, low voltage in batteries, etc., these engines don’t just start up like a Cummins. They are very difficult to start if these components aren’t up to par. The reason why they are somewhat difficult to start is because of the indirect injection system that these engines are equipped with.
Your engine will not start in the morning if your glowplugs (all 8) are non functional, even with a new rebuilt engine.

That's interesting on the glow plugs. Most of my experience was with 6.2 Chevy and it started with a bit of plugs unless I plugged it in. The 91 7.3 is my first Ford.

So if it's getting fuel check the relay?

I'm hoping its something stupid simple. The trucks at a great price, sight unseen, but with shoulder surgery looming I don't have time to mess with it.

First thing, push in the schraeder valve on the fuel filter while cranking. No fuel spraying out = make sure you have fuel in the tank(at least 1/2 tank full), make sure that the lift pump is connected etc.

Agreed! It’s kinda like the guys that say nitrous blows up engines, like D.F says, nitrous doesn’t blow up engines, people do!

It’s all in how you use it...

Unfortunately I didnt get a chance to look at the truck last night. Going to try again tonight after work.

Figured the first thing I'd do is check the tank levels then Schrader valve. I'm not going bleed his injector lines for him. If I get it running the price might go up...lol

Does anyone know a good mechanic in Spartanburg/Greenville SC?

You should really bleed the injector lines if you can. If you know you can get diesel to the injectors, then you know you have a functioning IP. That's important, because if the IP is busted, then you'll have to drop a grand for a rebuild.

Don't worry about the price. The seller just wants that "piece of junk" gone.

And on your shoulder surgery, rotator cuff I guess, see if they will do the nerve block. You'll get over the hurt a LOT faster.
No pain pump, they mess up too much.

I'll see about that. Honestly I'm more worried about tearing it again after it stops hurting. I'm not the kind to slow down. I'm used to going 200mph with my **** on fire

I've seen magazine article that talk about people who use nitrous when build their computer controlled diesels for drag racing or sled pulling. I can't remember if any even said how much they were running. The nitrous itself doesn't really give you much power. It's an oxidizer that releases oxygen into the engine which allows you to burn more fuel. Of course a turbo will perform a similar task except that a turbo will get you more oxygen into the engine by shoving more air into the engine. The more fuel that you can completely burn, the higher your cylinder pressures will be. My opinion is that if you have a turbo that feeds a lot of air into your engine (not a "stock one) then you probably couldn't run a lot of nitrous before your cylinder pressures will be too high and you lift a head. It's all a balance. Air/fuel versus clamping the force of your head fasteners.
