Hey everyone, been on the forum for a while now getting advice on building my 460 for my 69 torino. Anyway, I've been needing a truck for a while and I ran across this F350 4x4 I really liked, turns out it has a 460, E40D, so I snagged it. It mainly a parts hauler.

The salesman said the motors been rebuilt but I see no visual evidence of it. Its got a ton of miles (225k) and still runs very strong. I've been driving to and from work for the last few days just make sure its sound. I've fixed a bad ground causing starting issues, fixed a vacuum leak, tension pulley was shot and some cosmetic stuff. Basically visually inspected everything and checked fluids.

Problem is, this morning couple of times the engine has just cut out while cruising, rpm drop almost to zero, come back up, check engine light flickers when the engine cuts, then everything is fine. I ran my obd-I code scanner on KOEO, everything came out 111,1,111,1 . Which I read means all is well. Its not running rich, and the only time its burning oil is morning startups

I suspect fuel filter? maybe pump? Does it have a pump for each tank? and a single fuel filter? Im not to schooled on these trucks and dual tanks. Plugs and wires seem to be in good shape.

p.s if this engine craps out, I'll use the efi and tranny for the Torino

It does have a pump in each tank. U have to buy the assembly. Does it come back to life when u switch tanks. I have one go bad on my 94 when it was still a fuelie but the truck never fluttered, just mad no top end power on the ont tank. I also had the switch go bad in the same truck that swithced tanks. Next time it does it try the flicking the swith from tnak to tank, may be bad contact in swith on the dash. There is no swithing valve in the frame on these trucks.

Any chance you can borrow a fuel pressure tester from someone. Look it to the rail and see what you have. I cant remember what they are supposed to have but you would see the pressure be in-consistant if its a pump. One more thing would be the stupid impact switch behind the passenger side kick panel could be screwing around.

Thanks for the response. When it happens it only last a couple of seconds, then its fine. I dont do anything but natuarally give it gas since I was slowing down in traffic.

I just ran new KOEO and KOER test's

KOEO test gets:
211 - PIP erratic or missing (which explains the engine cutting out)
542 - Fuel pump open, bad ground or always on. Power / Fuel Pump circuit

KOER test gets:
311 - Air system not working.

I didnt check the impact switch, is that the fuel cut off valve? Also, I havnt even tried the other tank, I hear the pump run and its empty, I just got the truck so havnt had a chance to flip it over to that tank.

Nice truck I have a 93 5 speed, you will want to figure out the bugs on yours and keep it as a parts hauler or other use. They do not make them like this any more, full floater Dana 60 front is very stout and can be made stronger with simple parts.
Get a competent friend to work the switch in the cab while you check the power leads to pumps, fuel press gauge on fuel rail, test light and volt meter you'll figure out the fuel pump issue in short time if that is where the problem lies.

Mine would cut out and loose power when I drove it warmed up down the road at 55+, turned out the "economy" distributor cap terminals where the rotor contacts where having a
small overheat problem and causing spark to jump all over. Replaced with a MSD BRASS terminal cap and rotor, really woke it up. Not saying this is your issue just check it.

see ya,,,

Thanks, im sure enjoyin it, truck is built like a tank. I drove it about 15 miles yesturday and it never happened. I do plan on swappin out the carp and rotor, and throwin on some headers, another thing im working if the dent in the bed (big dip in bed) may be making contact with the pump??? I wouldnt think the problem would be speratic if this was the case but who knows.

I'll see what I can figure out. I wish I had more details on that code its throwing though.
