RE: F53 460 Engine runs very poorly when heat soaked

Lots of F53-460 fuel pump problems, and threads,on the net. 2 things you can try,cheap and easy,replace the TFI and the fuel pump relay. Other things to try- at your risk- when it acts up,1-loosen or remove the fuel cap 2- when it acts up, throw trans in neutral, turn off and restart engine. I tried the TFI aka Ignition Module which is located on the front apron between the left headlight and radiator. So, not exposed to engine compartment heat. Bottom line, it did not resolve the issue. Thank you. TFI is only one part, there is the ECM (Engine Control Module) which is the "computer" or "brain" that controls ignition timing and fuel delivery to the engine. ECM has predefined fuel and ignition maps and uses a variety of external sensors (some which you have replaced) to determine timing and fuel delivery.. ECMs where often mounted in the engine compartment near the windshield, not sure where it is on a Chassis build.. Failing ECMs can affect engine performance.. ECM on OP's chassis is on the inside of the fire wall, just in front of the steering column. Not exposed to engine heat. Richard Richard, As it turns out, I didn't replace the TFI Ignition Module. The module that is on there looks really dark gray or black. It says Motorcraft on it. The dialectric compound is dry and powdery. I will get a new TFI but not install it until I get the problem to come back. I will then, immediately replace it. If the problem goes away that should be my solution. Either way since you suggested that i use a new gray one, I'll just leave it in. After all, the one in there is 26 years old. Richard, which brand do you recommend?

RE: F53 460 Engine runs very poorly when heat soaked

And the Check Engine Light stays unlit? YES. No check engine light. The CI light did come on 4 years ago when the fuel pump failed. It comes on briefly when starting then goes off once engine is running. (Normal)

RE: F53 460 Engine runs very poorly when heat soaked

Sounds like it could be bad catalytic converter My F53 Motorhome is 17,000 lbs GVWR. So, no catalytic converter installed from factory. I even confirmed this myself.

RE: F53 460 Engine runs very poorly when heat soaked

When you say full throttle, was the tachometer pushing 7-8,000 rpm's? If it was....you have torque converter problems....not engine problems. Throttle pedal to the floor. Engine speed about 1800 to 2000 rpm in low.

F53 460 Engine runs very poorly when heat soaked

My 1995 F53, 460cid runs poorly after being heat soaked. When engine is cold it runs like gang busters. After a fuel stop and the engine has soaked up the heat due to no airflow through the engine compartment, there is virtually no power at full throttle. Once above 3000 rpm it starts to get power but misses and hesitates. Once up to highway speeds the engine smooths out and runs fine. I bought the unit with 60,000 miles on it, 6 years ago. I have replaced the following: fuel pump, spark plugs, ignition module, both coolant temp senders, IAT sender, water pump, radiator, timing cover, thermostat and all related coolant hoses. I replaced the fuel pump in 2017 because it would only go 35 mph. I was able to hobble it home and make the repair. It was a very easy task, once the fuel was off-loaded. The fuel pump solved the main issue and it runs well until I let it sit for 30-40 minutes during refuelling. One other note, it tends to do better in cooler climates. Not much problem at all in winter months, here in North Idaho. Most recently, we were coming home from California and our road has one portion about 3/4 mile that is about 7-8% uphill. I could not get past 5 mph using full throttle. It usually pulls the hill at 20-25 mph. If anyone has any ideas, I would appreciate it.

Repair and electrical manual purchase and download

I own a 1995 Fleetwood Flair 32W on a Ford F53 chassis. It has less than 85,000 original miles. It is in terrific shape except for neglect issues with the previous owners. (2 previous owners) I would like to purchase and download a repair and electrical manual for it. I would appreciate any and all suggestions. Thank you, ahead of time. Donald UPDATE: I found a website that sells factorymanual downloads. Factory-Manuals.com , has factory manuals for download. I paid $49 for the Ford Factory electrical manual for the 1995 F53 chassis. I found the information within minutes, and was able to partially solve my issue. When I get home from vacation, I will make the permanent repair. Thank you to those of you that replied to my post. Happy Trails Donald
