Found myself trying to decide between a fuel pickup issue and electrical problem for my Triton V10 that keeps dying during sharp turns into parking spots and tight corners. The engine drops to approximately 500 RPM before completely shutting down, though it restarts immediately without codes. This occurs on a 2006 F53 chassis with 43,000 miles.

The stalling pattern is consistent with power loss during low-speed turning situations, creating safety concerns due to loss of power-assisted braking and steering. Engine performance is otherwise normal during straight-line driving and highway operation. Need systematic troubleshooting methodology to identify root cause - what are the primary diagnostic steps for V10 stalling specifically during turn scenarios? …more

Woke up this morning hoping my 1995 F53 motorhome with the 460 7.5L would run smooth after replacing the ignition control module yesterday, but it's still stalling randomly. It keeps stalling every time I come to a stop - literally dies on me at around 5mph just as I'm braking. The power steering goes out and it's a real struggle to get stopped safely.

I can restart it immediately and it runs fine as long as I keep giving it gas, but this happens at EVERY stop sign and red light. Currently, it won't start at all - just cranks with no spark. I previously had an EGR code 334 that went away after replacing the EVR sensor.

My fuel pressure gauge was showing 30-32 psi at idle and about 40 psi at wide open throttle. When I tested the vacuum line on the fuel pressure regulator, no fuel spilled out and the pressure didn't change.

I've already replaced many parts (including distributor cap, plugs, wires, EGR valve, ICM, fuel pressure regulator) with only 2,000 miles on them. I discovered that swapping the ignition control module seems to temporarily fix the issue - it starts with a new ICM but dies when I return to the original one.

I'm really concerned about potential highway driving with these intermittent starting problems. Is this a common issue with these 460 engines? …more
