Ford F53 7.5L RV Won't Start: Fuel Pump Relay Voltage Drop Fix

Woke up to my 1996 Ford F53 7.5L motorhome eating through my patience and wallet with this no-start issue that keeps coming back. It cranks strong but absolutely will not start, and I've been chasing this problem for weeks now. The engine ran fine for about 3-4 minutes one day, then just died and hasn't started since.

I've already done quite a bit of diagnostic work:
- Replaced PCM and distributor
- Fuel pump works when powered directly
- Battery is fully charged
- Checked fuses and relays
- PCM relay voltage drops from 12.2V to 9.3V with key on
- Fuel pump relay only shows 3.3V at pin 86 (should be 12V)
- Inertia switch tested at 1.7V at connector
- ANL 178 fusible link fluctuates between 0.3-0.6V

The engine will only start with starter fluid when the SPOUT is removed. I'm getting only 5.5V at the fuel pump connector.

Has anyone dealt with this specific issue on an F53 chassis? I really need to get this RV back on the road and I'm running out of ideas! …more

Ford E450 V10 Reliability: Expected Mileage and Longevity Guide for RV Owners

Nobody prepared me for staring at this 2018 Jayco Greyhawk 29MVP with Ford E450 chassis showing 54,000 miles and wondering if I'm looking at a money pit. The unit appears well-maintained with quality features including auto-leveling, fiberglass roof and nose, plus J-ride suspension. However, the odometer shows 54,000 miles, which exceeds my initial target range.

I need to assess whether this mileage represents significant wear on the E450/V10 drivetrain combination. What is the typical service life expectation for these engines when properly maintained? At what point should mileage become a primary concern versus overall mechanical condition? …more

Ford V10 Triton Engine Maintenance Guide: EGR Delete vs Regular Service Tips

Spent years doing regular EGR maintenance on my old gas motorhome without issues — but this 2007 Fleetwood 31' Tioga with Ford V10 Triton has me second-guessing everything. I keep reading conflicting information about EGR delete procedures on V10 engines, and I'm worried I might make things worse if I mess with it.

Is the EGR delete modification actually necessary on this 2007 3-valve V10, or am I overthinking this? I don't want to void any warranties or create problems that weren't there before. Would I be better off just sticking to regular maintenance instead of modifications? I'm looking for reassurance that I'm taking the right approach to keep this engine running reliably for years to come. …more

Best Cummins 6.7 Scan Tools for RV Diesel Diagnosis & DPF Regen (2024

The internet seems to give me six different answers about which scan tool actually works with my 2019 Fleetwood's Cummins 6.7L—am I missing something obvious here? Need comprehensive coverage for reading and clearing fault codes, monitoring engine parameters, and performing forced DPF regeneration cycles.

Considering several options including the Foxwell HD500, Ancel heavy-duty scanners, and various BlueFire/Inline adapters available through different suppliers. Price ranges vary significantly from budget OBD2 adapters to professional-grade diagnostic equipment.

Looking for detailed comparison of available scan tools specifically for Cummins 6.7 applications - both professional-grade and DIY-friendly options. What are the key features, compatibility considerations, and real-world performance differences between the various diagnostic solutions for this engine platform? …more

Safari Motorcoach LPG Tank Refill for Stationary RV Setup

Between my toolbox and the YouTube tutorials I've watched, I'm ready to tackle the LPG tank refill setup on my permanently parked 2000 Safari Sahar 32-footer. Since my wife and I live in California and visit several times per year to help her aging parents, the RV serves as a stationary dwelling with full hookups for shore power and water.

The challenge is that the coach won't be moved to drive to propane filling stations, so I'm exploring on-site refill options. I'm specifically interested in potentially transferring propane from a standard 40lb grill tank to our RV's fixed tank. I want to understand what type of fitting our Safari Sahar has and what safety considerations or special equipment might be required for liquid-to-liquid propane transfer.

Since we'll need heating during colder months and my wife will sometimes be at the RV without me, I want to ensure a reliable and safe refill method. What are my options for refilling the LPG tank without moving the motorcoach? …more

Remote RV Diesel Fueling: Complete Guide for Campground Fuel Strategies

Last night at 11 PM I'm staring at my diesel RV's fuel gauge showing nearly empty — need to figure out remote campground fuel strategies before we head out this morning. With a 5 gallon Harbor Freight stick transfer pump, I've been able to add fuel when truck stops aren't convenient, but I'm concerned about static electricity risks.

My current setup involves using the pump to transfer diesel with the fuel can on a camping table, since my RV's fuel inlet is located under a slide. I pumped 10 gallons successfully, but I'm wondering about the safety of this method.

I know there are static electricity concerns when transferring fuel, and I'm curious about the specific risks with diesel. How safe is it to transfer fuel when the can isn't directly grounded to concrete? Are there best practices I should follow when manually adding diesel in remote locations? …more

RV LP Gas Detector False Alarms: Complete Troubleshooting Guide

Already tried everything but my RV's LP gas detector has false alarms in the garage, keeps beeping at random times, AND won't reset properly. Even with the LP tank completely shut off, the alarm still goes off within hours. It's located in the bottom of the fridge cabinet.

I've checked everywhere for actual leaks - can't smell anything, and all my appliances still light immediately when I take the RV out. The detector seems fine outside but becomes a nightmare indoors. I'm wondering if it's the sensor going bad, poor placement, or if there are other things that can trigger these detectors besides actual propane leaks?

I really need a complete breakdown of what causes these false alarms and how to fix this issue once and for all. Should I be looking at replacing the detector entirely, or are there troubleshooting steps I'm missing? …more

Ford F53 Motorhome Key Programming Guide: Security Features & Programming Tips

Apparently my 2008 Ford F53 motorhome is 16 years old and starting to have key programming issues — should I attempt DIY programming or call a locksmith? I just dropped $176 on two new transponder keys for my 2024 Windsport 34R (2022 F53 chassis) because I only had one set and didn't want to get locked out in the middle of nowhere wearing my pajamas and fuzzy slippers (again).

The Ford dealer quoted me another $140-170 to program these fancy chip keys, insisting I'd need to haul my 35-foot house-on-wheels down there for the programming. But the parts guy said "try them first" - and wouldn't you know it, both keys fired right up without any programming!

So what's the deal here? Are these unprogrammed transponder keys going to mysteriously stop working next Tuesday? Did I just dodge a bullet, or am I missing out on some important anti-theft features that actually matter? I'm feeling pretty smug about saving that programming fee, but also slightly paranoid that my motorhome might strand me at the worst possible moment! …more

Sony VCB-62MH RV Camera Monitor Replacement: Complete Installation Guide for RV Coaches

Already cleared my Saturday schedule to swap out this Sony VCB-62MH RV camera monitor — what tools and prep work should I have ready beforehand? The Sony VCB-62MH rear view camera monitor in my 2008 Phaeton finally died, and of course Sony doesn't make them anymore. I've been searching everywhere for a replacement but everything I find is either way too big for the existing dash opening or doesn't work with the Sony cameras that are still perfectly fine.

I really don't want to replace the entire camera system - that would cost a fortune and the cameras work great. I just need the monitor replaced. Has anyone successfully found a workaround that reuses the existing Sony cameras and wiring? I'd love to keep the automatic switching feature for the side cameras when using turn signals if possible, but at this point I just need something that works and fits in the dash opening. …more

Ford F53 Chassis Firewall Wiring: Finding Brake LED Through-Holes

Opened up my 2022 Holiday Rambler 36DB for spring prep and once again I'm staring at my 2021 Ford F53 chassis firewall wondering where those brake LED through-holes are hiding. I need to run the brake indicator LED wire from my toad to the dashboard inside the motorhome, but I'm having trouble locating the best firewall penetration point.

Rather than drilling a new hole through the firewall (which I'd prefer to avoid for obvious reasons), I'm hoping to find an existing through-hole or grommet that I can utilize. I've heard that Ford F53 chassis typically have several factory access points, but I'm not sure exactly where to look or which ones would be most suitable for this type of low-voltage wiring installation.

Can anyone provide specific guidance on where to find existing firewall through-holes on the F53 chassis that would work well for routing brake indicator wiring? I want to make sure I'm using an appropriate location that won't interfere with existing systems and will provide a clean, professional installation. …more

Ford V-10 Misfire Codes P0305 & P0307: Complete RV Engine Repair Guide for Motorhomes

Turned my compression tester on cylinders 5 and 7 and got 150 PSI readings, but I'm still pulling P0305 and P0307 misfire codes on my 2001 Ford E350 V-10. The engine runs smoothly overall, but the diagnostic codes are persistent.

I have replacement spark plugs and ignition coils available but want to ensure I'm following the proper troubleshooting sequence before investing time and effort. What is the recommended diagnostic approach for simultaneous misfires on cylinders 5 and 7?

Given that multiple cylinders are affected, should I prioritize certain components over others, or is there a systematic order that typically yields the most efficient resolution for this engine configuration? …more

Ford E450 V10 Spark Plug & Coil Replacement Guide - RV Engine Maintenance Tips

After handling coil swaps on my old Chevy like they were nothing, this Ford E450 V10 setup has me completely intimidated and second-guessing everything. I've heard cylinder #3 is particularly difficult to access and I'm scared I might break something or use the wrong tools.

I tried using a 7mm wrench like some sources suggested, but it doesn't seem to fit properly and I'm afraid of stripping the bolt heads. I'm also concerned about how to safely reach the coils without damaging other components.

Can someone please walk me through the safest approach and tell me exactly what size wrench I should be using? I'd rather ask for help than risk making an expensive mistake. …more

Ford F53 Chassis Misfire Problems: Early Spark Plug & Coil Failure Solutions

Walked out to my 2021 Class A motorhome this morning facing the third Ford F53 chassis misfire this year and I'm done throwing parts at it blindly. We've got less than 20,000 miles on the odometer, but recently experienced rough running and got a check engine light. When I took it to a Ford dealer that services Class A rigs, they diagnosed misfires in two cylinders and recommended servicing the entire fuel system. I ended up having them replace all eight spark plugs, plug wires, and ignition coils since we were already dealing with failures.

The coach now runs better than it ever has since new, which makes me think the original components may have been subpar from the factory. What's really bothering me is that we shouldn't need major ignition system work this early in the vehicle's life. I'm curious if other owners of 2021 or newer F53 chassis motorhomes have experienced similar premature failures with their spark plugs, ignition coils, and plug wires? Is this pointing to some kind of quality control issue with Ford's ignition components on these newer chassis, and should I expect better reliability from aftermarket replacements going forward? …more
