IH 454 problems, possible fuel ejector pump

Ron TN · Sep 1, 2008

My Dad has an IH 454 diesel. It will start if he chokes it and run for 20-30 seconds then dies. It won"t take fuel. I see the injector pump but can"t find any info on it. I found a couple places selling a "fuel pump" that says its for a IH 454 diesel but I cant find anything on Dad"s that looks like the pump they show.

It appears fuel is pushed from the tank by gravity to a fuel filter with drain on right side then sent to another filter on the left then to the injector pump. Please give me any advice or thoughts. Thank you

What do you mean by "choking"?

Sounds like either a badly plugged fuel filter or bad piece of fuel line. My 484 had a little short piece of rubber fuel line go bad and it did pretty much the same thing. The line looked pretty good from the outside, but the inside had collapsed so the engine couldn't get proper fuel.

What confuses me is when you talk about "choking" a diesel, do you mean you place the lever in "cold weather start"?.

pushing the choke lever down like you would to stall it out. He has to originally do this to start it then pull the lever up.

It will also start up if he is turning it over and I break loose any injector screw or bleeder screw.

yes cold weather start

I don't think it is your fuel pump. The original fuel line on my 484 was metal braided rubber and only a few inches long going from the fuel filter up to the steel fuel line, but the inside had collapsed. If the tractor sat for awhile, then it could be started and it would only burn what fuel had managed to get through the line and then quit. I think I would start with that before paying for an injector pump.

Check for a plugged return line from injction pump or fuel rail return back to the tank.

Don't know anything about a 454 but if he has to cut off the fuel first before it starts and lasts for 30 seconds , is he building up fuel while it is off, releases the fuel for a start and then no fuel to continue. I would look from the tank to the cut off lever,.. just a thought.

don't replace the expensive equipment first, but prove it is faulty.
Do you have a fuel pump[ worked off the camshaft] before the injector pump/.if so ,is it working.??
remove fuel line at injector pump and watch flow while cranking.

I would look for clog in fuel tank first. Undo line going to primary filter. Fuel should pour out of it. I have unclogged it by taking fuel tank cap off and blowing air back through line.
