Results for "stalls"

RV cranks for 10-15 seconds before finally firing up, and it's getting worse each week. Used to start on the first crank every time. Fuel pressure seems low at the rail but I'm not sure if it's the pump, filter, injectors, or something else entirely in the fuel system. …more

According to my troubleshooting so far, I've replaced the fuel filter, cleaned the fuel lines, checked all the connections, and even swapped relays — but my 1999 Pace Arrow F53 still won't get fuel to the engine. The original fuel pump has been operational for 27 years, exposed to gasoline storage conditions throughout this period.

Given the extended service life and potential for roadside failure, I'm evaluating whether proactive fuel pump replacement represents sound maintenance strategy. Seeking technical assessment on replacement timing and expected performance outcomes with quality aftermarket units from established suppliers.

What are the documented results from similar preventive fuel pump replacements on this chassis configuration? Is the investment in preemptive replacement justified based on reliability data? …more

Replaced multiple parts but I'm still standing in the auto parts store aisle staring at diagnostic tools with no clue which one I actually need for my RV's stalling and transmission issues. When I'm cruising and let off the gas, sometimes the RPMs drop like a rock, other times they just hang there until I slow down more. That's weird enough, but here's the real kicker - every now and then the whole engine just dies on me when I'm rolling up to a stop sign or red light. Maybe happens twice in 600 miles or so, so it's not constant but definitely not normal either.

I'm wondering if these two issues are connected somehow? Like could whatever's causing the stalling also be messing with how the transmission acts when I let off the throttle? Really hoping someone has seen this combo before because I'm in Germany and finding RV-specific help is tough.

I'm looking for any insights from folks who might know what could cause this - hoping to get to the bottom of this before it becomes a bigger problem! …more

Turned the key in our "new" 1990 Fleetwood Tioga E-350 and my wife immediately said "that's not starting, honey" — now I'm completely stumped. The engine turns over like it wants to start but just won't fire up. I've already replaced the fuel pump inside the tank, but I'm wondering if another pump might need replacement. I don't want to just start throwing parts at it. What's the best systematic approach to figure out why my Tioga won't start? Are there common failure points I should check first on these older E-350 based motorhomes? …more

Our '04 Southwind with the Ford V10 started with minor hesitation last month but now it's turned into full P0171 and P0174 lean condition codes. Engine runs fine otherwise - no rough idle, no hesitation, fuel economy seems normal. Just these annoying codes that keep coming back.

I've heard the V10 has some common issues that cause these dual lean codes. Already checked the obvious vacuum lines and cleaned the MAF sensor, but wondering what the most likely suspects are when you get BOTH banks showing lean. Is there a systematic way to track this down, or should I just start throwing parts at it?

Really don't want to take it to a shop if this is something with known failure points on these engines. What would you guys check first? …more

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

The mechanic wants to replace all my fuel injectors on my 1996 F53 460 motorhome after I installed a Banks Power system with Accel 24 lb, but this sounds like complete overkill. injectors. It's been running rough, especially at idle, and I'm getting intermittent check engine lights. I don't want to make things worse by guessing or doing the wrong repairs.

I'm honestly a bit intimidated by fuel system work - I've heard horror stories about people causing expensive damage. The injectors I installed were Accel 24 lb., and I want to confirm if these are correct for this engine. I'm planning to pull a plug soon to check my fuel mixture, but I need some expert advice on the safest way to diagnose whether my injectors are actually the problem. I want to be absolutely sure before I start throwing parts at it or risk damaging something else in the fuel system. …more
