Re: 2000 Ford F53, V10 cranks but not starting, & solution
tommykelly: The relay is in the power distribution center, a collection of fuses and relays in the engine compartment. On my F53 chassis it is right in the middle, at eye level, hard to miss, and it is relay number 6 I believe. Try the picture now, I tried to change the properties.716Views0likes0CommentsRe: 2000 Ford F53, V10 cranks but not starting, & solution
"And the rest of the story", as Paul Harvey would say. I got the rig home and still had the bad relay in the tool box. I decided to open it up before tossing it to see if I could see what went bad. What I found surprised the heck out of me, ANTS. The whole case was full of small red ants, the little fire ants found in South Carolina. They were between the contacts and completely filled the inside of the case. Photo of relay716Views0likes0CommentsRe: 2000 Ford F53, V10 cranks but not starting, & solution

Another thing could be a kill switch. I don't know if rv's have them but cars do. When they get in accidents the switch kills the computer and has to be reset. ZMAN-AZ. Had swapping the computer power relay and the heater blower fan relay not cured my problem, I think a bad computer would have been the prime suspect. But I don't know how to test it, or where to locate it. What I needed was a step by step trouble shooting process to solve a no start problem, but I couldn't find one. I bought the RV used and the only manuals I have are what I could piece meal from online and print out, not complete by any means.715Views0likes0Comments2000 Ford F53, V10 cranks but not starting, & solution
2000 F53 V10 not starting, and solution. I am posting this in hopes that it will help others, and to invite comments as to what I could have done better. I am sorry for the length. If only interested in the solution, skip to the end. My RV is a 2001 Pace Arrow, on a 2000 Ford F53 chassis, with a V10 and 65000 miles. I had just filled the tank with non ethanol fuel 3 weeks ago, and still have approximately 70 gallons on board. We used it three weeks ago and then stored it at the campground. On arriving for a long weekend, temperature in the upper 80s, found that the motor would turn over fine, but it would not start. And the steps would not extend. After trying it several times, wiggling fuses and trying it again, I towed the RV with my pickup truck to our reserved site, set up, and with the A/C on, pulled out the manuals while the family headed to the pool. I did have internet service, one reason I reserve this particular site, and proceeded to read several posts online that indicated a probable fuel pump issue, with the pump being in the tank. I did a quick check of fuses with an ohm meter and found all seemly OK. Looking at the fuel tank, I realize there are not only 4 large straps holding it in place, but also another cross member bolted in to support the rear jacks that would have to be removed to drop the tank, and the jacks removed as well. I took a five mile trip to O’Riley’s Auto Parts and bought a fuel pressure gauge, a battery charger, and a can of starting fluid, all the time thinking about the campground’s policy of no repair work on the property, and would it be conceivable to cut an access hole in the floor. After connecting the gauge to the fuel rail, I confirm I have zero fuel pressure. Continuing through the manual and finding more information on the internet, I check the emergency power switch to the fuel pump, located right where it is supposed to be, beside the steering column. It is OK. I swap the relays for the fuel pump and I think the driving lights or horn, which are both in the power control box under the hood. The status remains the same. After trying to start the motor again, the steps starting working. I discount this, as I have had a couple minor problems with the steps in the past, so I believe this is a separate issue. At this point, our guests for the weekend arrive, so I put the testing aside for the evening and regroup. The next morning, with a freshly charged battery, and trying to figure out how to confirm there is power to the fuel pump, I get around to trying to start the motor with the starting fluid. Nothing, no popping, backfiring, or even a hint of fire. I pull the number 5 coil pack and put a spare spark plug on it and confirm, no spark. I am dismayed that I have another problem, but at the same time happy that perhaps the fuel pump is OK. Back to the manual and internet. I find that a PCM module controls power to the fuel pump and ignition. I check the fuses to the PCM. It is OK. I swap the relay that provides power to the PCM with the relay for the heater blower motor. This time, the motor fires up in 5 seconds, music to my ears! And better yet, the fan blower now does NOT work! Finally, I have a bad FAOB-14B192-AA relay5.3KViews0likes12CommentsRe: What did you do to your Class A MH today???
Last weekend - drained all the antifreeze and sanitized the water system. Repaired the power mirrors (thanks mike), found they were wired into the power window circuit, and that fuse was missing. Repaired the monitor panel, found the circuit board dislodged from it's plastic holders inside the cover. Installed a Prodigy trailer brake controller. Began storing things removed from the previous toy hauler, into the basement compartments, guessing where they should go. First trip is just over a month away and we can't wait!! Next weekend, tackle the non running generator.363Views0likes0Comments
