 Topic: Hey,,this might be the best time,,,,,
Posted: 20 Feb 2022 at 10:27am |
Since our Good Buddy is busy doing his long anticipated Retirement plans,,,I'ma sneak this FORD request seeing as how he has that slight dislike for them great trks,,,,,,, On my 2000 F150,,I'm bout to go batty trying to figure why it keeps stopping on me. It done it on me on the way to the dump with a full load of shingles,,,and stopped right of the friggin intersection,,,,!!! cranked til battery almost gone and finally did start. went and unloaded the trailer and the SOB died again on way home. Let it set and after 5 mins it started up and I got home. Next day,,it done it again,,, Got on internet and suggestions were the CRANKSHAFT POSITIONING SENSOR, so I replaced the one that been in there since trk was new. (That was a heck of a job!) Trk fired right up and thought issue solved but next day Son called that it stopped in town! He gets it going and come home. It ran ok til next day, the SOB stopped on me again on way to dump with another load of shingles. This is getting very OLD,,,,
I hooked up my fuel pressure gauge on the fuel rail and fuel pressure was on 25#,,,but trk was running ok,,,? I kept thinking fuel pressure was suppossed to be around 35# - 40#,,but trk was running good when of a sudden it stopped again,,,,, WTH? I checked the switch behind passenger door and it had NOT tripped
When engine stops, it's just like you turn key off. Jamie changed fuel filter and after a few trys,,it starts up again,,,,!! Somebody in a ford forum told Jamie that it was the FUEL PRESSURE REGULATOR,,so we install a new one and it starts right up,,,and then DIES after bout 5 mins of running fine,,,! SO, I come here on sore knees (from roofing) for some fool proof suggestions as to what problem could be,,,,right now I'm thinking FUEL PUMP but I aain't pulling the frigging gas tank til I know for sure When it dies,,it just like you turn key off,,like it may be electrical,,? (I gotta fix it before ole Shameless gets back on here,,,,,) Any suggestions,,,??? (remember I'm on sore knees)

Not sure, but could be your ignition module opens up internally when it gets hot. Should be to trouble shoot with volt ohm meter.

Joe, there is a schrader valve on the fuel rail, probably where you measured the pressure.. When the truck STOPS, push that little needle in and see if it SQUIRTS... You have some pressure when running, but you need to know what the psi is when it WONT RUN... The "regulator" will maintain pressure in the line overnight so it starts in the am.. So you can get a reading, WHEN OFF...... Also, when you turn the key "ON", but not "START" , the fuel pump runs for 3 seconds to prime the line to make sure it starts.. See if you can hear the pump............. or put the gauge on and leave it on... when MOTOR STOPS, open the hood and see what is on the gauge.
I would guess on a 20 year old truck, if you have not changed the fuel pump in 10 years, that is a good bet.

the pump puts out about 50 psi... that little regulator you replaced is set about 32 psi for idle... and it has a vacuum tube on it... when you hit the throttle and vacuum drops, the psi goes up to about 40. ........... if your regulator is NEW, then probably your pump cant put out more than 25 psi........ pull the vac hose off the regulator when running and see if the PSI moves.

How sloppy is the ignition key/switch?

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

Had basically the same problem on my '99 F150, turned out to be the fuel pump.

HMMMM... I'm going out on a limb here, FoundOnRoadDead, have you checked the blue oval fluid???  The main thing these newfangled computer controlled vehicles are for is to nearly force you to go to a dealer to keep from chasing your tail trying to fix a problem and liberate you from you bank account. Often when one sensor goes (say a CPS) it will take out others in the control circuit it works with.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

When I had to replace my fuel pump, I called the dealer and asked if I bought the pump would they install it. She said, yes, they do it all the time.
I bought it new online (Motorcraft) and took it into the dealer with the truck and had them replace it. Took all of about an hour and it was done. No way was I going to drop the tank or remove the bed. IMHO, this is a shop job.
So if you're sure it's the fuel pump then you might want to consider this as an option.

Last time i was at a Dealer Service Center was in 1989 when valve cover on a new truck started leaking.. I was out of town... Dealer did it under warranty for FREE... Other than that i have never had a major problem that needed Dealer........ Maybe its because i only drive FORDS !!!

what was weird was the pressure gauge on the fuel rail would hold 24# but of a sudden,, would fall to 5# and engine would die. We finally decided to pull tank and the filter on the bottom of pump was very full of black chit, so I told Jamie to go get a new pump and he just left to town,,,,so we're calling it a GW Bush for now,,,,,,, MANY THANKS for all the ones that helped and also the ones that worried along with us,,,, BUT,,BUT,,I wasn't quite thru,,,,I'f like to know what year the ford trks changed to the computor driven engines. Also for the cheys, I am so sick of the electronic BS, I am going to find one of the last year computorless trk models and rebuild, repaint and re everything ,,prolly settle on a mid 70's F150 with the Race track trim or one of the square body Chevys soon's someone tells me which years ,,,,,,I've had it with fuel pumps in tanks and all kinds of sensor Bull Chit,,,,,,

Joe, i bought a NEW 1989 F250 with a 351-V8 that had 8 fuel injectors... I almost passed on that truck due to the "NEW FANGLED STUFF " in place of a carburetor... So i know you got to be a few years prior to that to get rid of that... It also had TWO fuel pumps. One in the tank, and out outside the tank... Didnt have a "computer" or " PATS keys"... but it did have fuel injectors !! ........ ( i guess it has some type of logic, because SOMETHING was firing those injectors!)

Joe, the first tire service truck I had had a darn 460 in it. That dam think would just die whenever it felt like it. This was before cell phones. I walked many a mile looking for a phone to call a tow truck. Every time, the tow truck would hook on to the dam thing and drag it back to the ford dealership. It would start and run every time. I cant begain to count how many times this hunk.of junk did this to me. One day I pulled the air cleaner and looked in the carb. No gas, the dam fuel pump had been checked out just a couple days before. I knew it was good. I had a 1-3-5 lb hammer in the truck. I came real close to whacking that dam carburetor with the 5lb hammer but I used the 1 lb instead. I heard a "tink" sound. The dam thing cranked and started. The stinking float was sticking closed. They had to put a new carb on it to cure the problem. It was the only one of the 6 or 7 ferds I owned that didnt get the motor and transmission replaced. It got one or 2 trannys and at least 3 torque converters. Along with a new radiator and all tranny lines.

Ford changed some models to EFI in 1986-87, I believe they were all EFI by 88. Prior to that the 82-86/87 models used the Dreaded Feedback Carburetor (DFC) that used a computer-like contraption to control modified carburetor. THe DFC system cleverly combined all of the worst features of carburetors with all of the worst features of EFI and used none of the good features of either.
I drive an 85 F-150 with a 300-6 and granny tranny; the DFC has been removed and replaced with an old-school Carter YF carb and DS2 ignition. It suits my needs, but my needs are pretty simple.

So........the only vehicles worthy of buying are a minimum of 37 years old.
Well......I could see keeping an engine and tranny running that long and even longer no problem. In this neck of the woods, that's all you'd have though, is an engine, tranny, and tires. The rest will be gone, including multiple folds in the frame.

They exist.....but they're getting rare. One thing to be the first owner and keep at it. Can't imagine going shopping for anything that old and use for a daily driver. Good thing "everybody" doesn't want one!

Steve I can change your luck, just send it out here for one summer and let me use it on the farm. I’ve owned them all and for some reason I always find the weak link. Although drivetrain seems pretty good in all. I will say this these new GMs only take about 20,000 to plug a fuel tank vent. Talk about pissing you off when you fill fuel. Especially when you drive a 6.0 and your foot limits fuel mileage to 9mpg that’s more than a once a week cussing.

Ford started wired atuff in 82-83 with feedback carbs n such. The trucks became cheap garbage. Known as a Bullnose. In 85 they started EFI on the 302. That chit don’t like old age. In 1979 the last very good Fords rolled off the line. You’d do well with a pre throttle body Square body Chevy as well. The Chevy will drive better but the Ford is much tougher.
